Pozycja Open Access Alleviating Effects of Ascorbic Acid on Lead Toxicity in Goji (Lycium barbarum L.) in Vitro(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Krupa-Małkiewicz, Marcelina; Kruczek, Arleta; Pelc, Justyna; Smolik, Beata; Ochmian, Ireneusz; Department of Plant Genetics, Breeding and Biotechnology, West Pomeranian University of Technology, Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology, Szczecin, Poland; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin, Poland; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology, Szczecin, PolandLead (Pb) is the most common heavy metal pollutant in the environment. The objective of the presented study was to investigate the ameliorative effect of exogenous 1 mM ASA on key growth and biochemical parameters in Lycium barbarum seedlings under heavy metal (Pb(NO3)2) stress in vitro. Nodal cutting with an axillaries bud were used as an explants. The results showed that lead accumulation in goji explants had negative influence on morphological parameters of plant growth, such as shoot and root length. Lead caused a significant reduction in chlorophylls and carotenoid content, increased lipid peroxidation and induced significant accumulation of proline in goji leaves. Addition to MS medium 1 mM ASA greatly alleviated Pb-induced growth inhibition and Pb-induced MDA and proline accumulation. Presence of ASA in the MS medium under heavy metal stress increased plant fresh and dry mass with no significant effect on plant water content.Pozycja Open Access Cane Pruning IntensityoOf Vine as a Substantial Factor Influencing Physico-Chemical Attributes of Berries Cultivar ‘Regent’(Wydawnictwo Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Pachnowska, Kamila; Ochmian, Ireneusz; Department of Horticulture, West Pomeranian University of Technology Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology Szczecin, PolandThe research were focused on the assessment of quality attributes of berries cultivar ‘Regent’. The vines trained on Single Guyot training system were pruned at three intensities of 4, 6 or 8 buds per cane. Berries were harvested in three consecutive seasons (2013–2015) at the research station of West Pomeranian University of Technology Szczecin in Poland. ‘Regent’ grapes were analysed in terms of physical and chemical attributes, i.e. weights of clusters and 100 berries, total soluble solids, titratable acidity, pH, polyphenols, nutrients (Ca, Cu, Fe, K, Mg, Mn, N, P, Zn) and heavy metals (Cd, Pb). Our results showed that cane pruning intensity of vine cultivar ‘Regent’ had significant influence on the quality of berries, with the exceptions of cluster weight, titratable acidity and pH. Weight of 100 berries, total soluble solids and most of elements increased as the intensity of pruning increased. In turn, the lightest pruning treatment led to the greatest polyphenol, K, Cu and Fe contents in berries.Pozycja Open Access Comparison of Processing Fruit Quality of Several Grape Varieties Cultivated in Climatic Conditions of Poland and Bulgaria(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Angelov, Ludmil; Stalev, Bojan; Ochmian, Ireneusz; Mijowska, Kamila; Chełpiński, Piotr; Faculty of Viticulture and Horticulture, Agricultural University in Plovdiv, Mendeleev 12, 4000 Plovdiv, Bulgaria; Faculty of Viticulture and Horticulture, Agricultural University in Plovdiv, Mendeleev 12, 4000 Plovdiv, Bulgaria; Department of Horticulture, West Pomeranian University of Technology, Szczecin, Juliusza Słowackiego 17, 71-434 Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology, Szczecin, Juliusza Słowackiego 17, 71-434 Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology, Szczecin, Juliusza Słowackiego 17, 71-434 Szczecin, PolandWine producers have been working on selecting the most suitable grape variety for specific regions and therefore improving wine production technology for numerous years. Climate changes lead to change in grape quality; in the future these changes will have to be considered by the vineyard owners as they will affect cultivation methods, harvest dates and vinification process. The aim of this paper is to compare the quality of several grape varieties cultivated in different climatic conditions. Research material was collected from vineyards situated in the Szczecin Lowlands (Poland) and Plovdiv (Bulgaria). The study focused on three grape varieties: Cabernet Sauvignon, Cabernet Franc and Pinot Noir. Measured characteristics included contained physical parameters: ruit weight, bunch weight and length and firmness as well as chemical composition: soluble solids, acidity, pH, ascorbic acid and nitrates levels, anthocyanin index. Analysed fruit was also examined in terms of colouration and must colour changes during maceration. Climatic conditions of the crop location had significant influence on the chemical composition of fruits, for example Bulgarian fruit featured higher levels of extract and pH combined with lower acidity. The Cabernet Sauvignon variety, regardless of crop location, had the highest levels of extract and organic acids. The juice obtained from Bulgarian grapes was darker (L*) than the juice from the fruit harvested in Poland. On the other hand, the juice of Polish fruit had more blue pigment (b*). It was also found that a* and b* fruit colour parameters are highly correlated with the anthocyanin index.Pozycja Open Access Comparison of propagation method in in vitro and in vivo condition of Lonicera caerulea L.(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Krupa-Małkiewicz, Marcelina; Ochmian, Ireneusz; Smolik, Miłosz; Ostrowska, Krystyna Maria; Department of Plant Genetics, Breeding and Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Plant Genetics, Breeding and Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, SzczecinThe aim of the study was to determine the effectiveness of rooting of blue honeysuckle of ‘Wojtek’ cultivar in vitro. Moreover, suitability of different soil substrate for rooting the lignified herbaceous cuttings in vivo was evaluated. The process of disinfection was the decisive factor in the process of preparing the explants for the propagation. Among the disinfection solutions used for sterilization of ‘Wojtek’ microshoots, the best results were obtained after application of 10% NaOCl solution. Initiation and propagation of blue honeysuckle proceed with the highest efficiency in Murashige and Skoog (MS) medium, and no positive effect of BAP cytokine on this process was reported. Proper selection of composition of the medium guaranteed high performance of rooting of explants in vitro – lack of plant growth regulators (PGRs) in MS medium led to a decrease in the percentage of rooted plants. The addition of auxins to MS medium had a stimulating effect on plant height, length, and number of roots. In the greenhouse, four-node lignified cuttings in the medium prepared with perlite and peat were rooted with the highest performance. Rooting of lignified herbaceous cuttings in the substrate prepared with peat and perlite stimulated the development of the root system as well. The worst influence for rooted cuttings was observed in sand.Pozycja Open Access Comparison of the Quality of Fruits from the Vine Cultivars and the Influence of the Maceration Process on Wine Quality(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2014) Ochmian, Ireneusz; Mijowska, Kamila; Department of Horticulture, West Pomeranian University of Technology, Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology, Szczecin, PolandW Polsce w ostatnich latach obserwuje się wzrost zainteresowania uprawą i przetwórstwem winorośli. Charakter i jakość wina kształtuje wiele czynników, które określa francuski termin terroir. Obiektem prowadzonych badań były owoce winorośli odmian ‘Monarch’ i ‘Regent’. Oceniano wielkość i jakość jagód oraz wpływ temperatury i czasu maceracji owoców na kwasowość, pH i barwę wina. Owoce badanych odmian nie różniły się wielkością jagód. Większą zawartością ekstraktu charakteryzowały się owoce odmiany ‘Regent’, a większą zawartością kwasów oraz niższym pH świeżego moszczu i wina cechowała się odmiana ‘Monarch’. Najwyższą kwasowość odnotowano w przypadku win uzyskanych z owoców odmiany ‘Monarch’ poddanych ośmiodniowej maceracji. Wzrostowi odczynu wina sprzyjały wyższa temperatura i wydłużenie okresu maceracji. Barwa soku ulegała zmianie także po zakończeniu maceracji miazgi, tj. w czasie dojrzewania młodego wina. Sok gronowy i wino sukcesywnie ciemniały, jednocześnie następowała ekstrakcja związków nadających mu barwę niebieską, zwłaszcza w wyższej temperaturze.Pozycja Open Access The effectiveness of disinfection methods on germination of goji seeds (Lycium barbarum L.) in in vitro culture(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Kruczek, Arleta; Krupa-Małkiewicz, Marcelina; Ochmian, Ireneusz; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Plant Genetics, Breeding and Biotechnology, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, SzczecinUsing disinfectant components is one of main ways to control of fungal and bacterial contaminations in the in vitro culture. Alternative to commonly used chemicals is ozonation. The present study was focused on the efficiency of seeds disinfection of two goji cultivars ‘A’ and ‘New Big’ using eight different treatments, 7%, 10% and 15% NaOCl and 0.2% HgCl2 for 15 minutes each, O3 gas and O3 in water for 5 and 15 minutes. The highest percentage of germinated seeds of ‘A’ and ‘New Big’ (respectively 62% and 78%) with the lowest number of infections (respectively 8% and 14%) was obtained after using 7% NaOCl solution. Less effective was 0.2% HgCl2 solution, where the percentage of germinated seeds of ‘A’ and ‘New Big’ was lower (respectively 37% and 30%). However, after O3 in water treatment of goji ‘A’ and ‘New Big’ for 15 minutes the percentage of germinated seeds was the highest (respectively 47%, and 53%) and sterility of the cultures of goji ‘A’ was 100%. In addition to, the ozonation of the seeds showed similar disinfection efficiency, as with 15% NaOCl solution. Therefore, ozone gas makes an alternative for commonly used disinfectants.Pozycja Open Access The effects nano-silver on contamination of spring barley ‘Eunova’ in vitro(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Krupa-Małkiewicz, Marcelina; Ochmian, Ireneusz; Mijowska, Kamila; Cendrowski, Krzysztof; Department of Plant Genetics, Breeding and Biotechnology, West Pomerania University of Technology, Szczecin; Department of Horticulture, West Pomerania University of Technology, Szczecin,; Department of Horticulture, West Pomerania University of Technology, Szczecin,; Nanomaterials Physicochemistry Department, West Pomeranian University of Technology, SzczecinOne of the available methods to control in vitro contaminations is nano-silver. Nanosilver is a non-toxic material which shows high capabilities in eliminating microorganisms, e.g., bacteria, viruses or fungus. The aim of the current study was to evaluate the potential of nano- -silver particles on decontamination, growth parameters (plant length, root length) and leaves colour of spring barley ‘Eunova’ in in vitro culture. Plant material consisted of embryos of barley which were placed on MS medium supplemented with 4.0 and 6.0 0 mg ・ dm–3 of nano-silver or submerged in 50 or 100 0 mg ・ dm–3 of nano-silver for 2 or 4 h. The control consisted of embryos treated with 70% alcohol. After 28 days it was observed, that both of the disinfection methods, operating time as well as concentrations of nano-silver, had an influence on a number of contaminations, shoot and root length and colour of the barley leaves. The smallest efficiency (100% contaminations) was found after embryos submerged in 50 mg dm-3 of nano-silver for 2 h. On the other hand, the best disinfection efficiency (0% infection) was obtained when 4.0 0 mg ・ dm–3 nano-silver was added to MS medium. Barley embryos soaked in 100 mg ・ dm–3 in nano-silver solution and grown on MS media with addition of nano-silver independent of their concentration showed similar disinfection effectiveness.Pozycja Open Access Fruit Quality of Highbush Blueberry (Vaccinium corymbosum L.) cv. 'Duke' Depending on the Method of Cultivation(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2014) Ochmian, Ireneusz; Kozos, Karolina; Department of Horticulture, West Pomeranian University of Technology, Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology, Szczecin, PolandW Polsce obserwuje się wzrost zainteresowania konsumentów żywnością ekologiczną. Płody rolne z gospodarstw ekologicznych są postrzegane jako produkty zdrowsze i zasobniejsze w substancje bioaktywne. W pracy określono wpływ sposobu uprawy krzewów borówki wysokiej odmiany ‘Duke’ (konwencjonalnej i ekologicznej) na jakość plonu: wielkość owoców, ich jędrność i skład chemiczny. Badania przeprowadzono w latach 2009–2011 w Pracowni Sadownictwa oraz w gospodarstwie produkcyjnym. Owoce z plantacji ekologicznej były większe, w plonie ogólnym było również więcej owoców dużych (> 12 mm). Owoce te były jednak mniej jędrne oraz charakteryzowały się mniejszą odpornością na uszkodzenia mechaniczne. Jagody zebrane z krzewów uprawianych konwencjonalnie charakteryzowały się większą zawartością ekstraktu i azotanów. Niezależnie od sposobu uprawy owoce małe (< 12 mm) były bardziej jędrne (zarówno w osi wysokości, jak i średnicy) oraz zawierały więcej ekstraktu. Owoce małe oraz zebrane z krzewów uprawianych konwencjonalnie charakteryzowały się również większą zawartością związków polifenolowych, zwłaszcza antocyjanów i flawonowi. Owoce małe zawierały również więcej kwasu chlorogenowego.Pozycja Open Access The Fruits Quality Impact of Four Berry Plant Species and Their Maceration Period on the Quality of Wines(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2013) Ochmian, Ireneusz; Dobrowolska, Agnieszka; Chełpiński, Piotr; Mijowska, Kamila; Department of Horticulture, West Pomeranian University of Technology, Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology, Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology, Szczecin, Poland; Department of Horticulture, West Pomeranian University of Technology, Szczecin, PolandPorównano jakość owoców czterech gatunków krzewów (porzeczka czerwona i czarna, jagoda kamczacka oraz borówka wysoka). Określono także wpływ długości czasu maceracji na barwę oraz skład chemiczny moszczu oraz win wytworzonych z tych owoców. Największymi owocami, o największej zawartości ekstraktu (17,1%), a jednocześnie o najmniejszej kwasowości (0,53 g · 100 g–1), były owoce borówki wysokiej. Owoce porzeczki czerwonej były najmniejsze, zawierały najmniej ekstraktu (11,2%) i związków polifenolowych (38,5 mg · 100 g–1). Wina otrzymane z owoców borówki wysokiej cechowały się zbyt niską kwasowością (2,4 g · L–1). Kwasowość wina otrzymanego z owoców porzeczki czarnej była bardzo wysoka (7,4 g · L–1), wysokie również było stężenie kwasu mlekowego (3,0 g · L–1). Najciemniejsze (L*22,38) były owoce jagody kamczackiej, a także pulpa z nich przygotowana (L*22,55). Najjaśniejszą pulpę otrzymano z owoców porzeczki czerwonej (L*34,56). W trakcie maceracji wszystkie pulpy ciemniały (parametr L*); nastąpiło wyługowanie związków barwnych ze skórki (parametry a* i b*). Przedłużanie czasu maceracji nasilało ten proces. Również wina w trakcie dojrzewania ciemniały. Wszystkie otrzymane wina zawierały znacznie mniej polifenoli niż owoce. Długość procesu maceracji miała niewielki wpływ na zawartość tych związków w winach.Pozycja Open Access The Impact of Cutting and Mulching Grapevine Regent on Yielding and Fruit Quality(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2013) Ochmian, Ireneusz; Grajkowski, Józef; Chełpiński, Piotr; Strzelecki, Roman; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, SzczecinBadania przeprowadzono w latach 2010–2011, w Pracowni Sadownictwa Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie. Określono wpływ mulczowania gleby oraz liczby latorośli na łozie na jakość i wielkość plonu winorośli odmiany Regent. Krzewy posadzono w glebie gliniastej, III klasy bonitacyjnej, zasobnej w składniki mineralne. Ściółkowanie gleby okazało się niekorzystne ze względu na pogorszenie jakości owoców. Winogrona zawierały mniej ekstraktu (14,1%), więcej kwasów organicznych (0,90 g) i azotanów (83 mg) oraz niższym odczynem soku (3,25) w porównaniu z roślinami nie ściółkowanymi. Cięcie łozy na sześć oczek wpłynęło na uzyskiwanie większych gron, dłuższych (16,4 cm) i o większej masie (208 g) w porównaniu do gron zebranych z roślin prowadzonych na dziesięć pędów. Prowadzenie krzewów na krótsze łozy powodowało lepsze doświetlenie roślin, co wpłynęło na zwiększenie zawartości ekstraktu w owocach (15,8%) i obniżenie zawartości azotanów (71 mg). Owoce były również jędrniejsze (186 G), ciemniejsze (parametr L* 23,54) i o większej zawartości substancji odpowiedzialnych za barwę niebieską (parametr b* –12,19), wymagały natomiast większej siły do oderwania owocu od szypułki (119 G).Pozycja Open Access The influence of fertilisation urea phosphate on growth and yielding bush of two highbush blueberry cultivars (V. Corymbosum)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kozos, Karolina; Ochmian, Ireneusz; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, SzczecinAn interest in highbush blueberry cultivation is growing in the world. An increase in the demand causes high prices of fruits. The success of cultivation depends on providing soil with a low pH value to the plants. The study specifies the influence of different doses (30 and 60 kg N · ha–1) of physiologically acidic urea phosphate (17.7% N, 44.6% P2O5) on the growth and yield of highbush blueberry shrubs. The studies were carried out at the Department of Horticulture, West Pomeranian University of Technology in Szczecin, at a production plantation specialized in the cultivation of highbush blueberry. The bushes were planted in soil classified as sandy silts with the content of organic matter at 4.1–4.2%. The following parameters were measured in autumn: the height of the bushes, the length of one-year growths, the number of one-year shoots growing on roots, the green index, leaf area and yield, fruit weight and firmness. The use of urea phosphate influenced the increase in the yield and size of fruits of both highbush blueberry cultivars, it did not, however, influence the increase in the height of bushes and the length of one-year shoots. It stimulated the plants to produce shoots growing on roots and the formation of larger leaves with a higher green index value as compared to unfertilized plants.Pozycja Open Access The influence of shurbs cutting method on yielding and quality of the goji berries (Lycium barbarum L.)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kruczek, Arleta; Ochmian, Ireneusz; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, SzczecinIn the experiment were compared: the growth of shrubs, yielding, the physical parameters of fruits and their chemical composition depending on the method of cutting bushes – the amount of main shoots. Research material consisted of goji berries grown in Department of Horticulture Research Station of the West Pomeranian University of Technology in Szczecin. Goji berries (Lycium barbarum L.) are characterized by high potential of health promoting properties and nutritious. They have been extremely important part of traditional Chinese medicine for ages. They are used there as a very important part of a healthy diet, due to the appearance of the complex polysaccharide valuable LBP (Lycium Barbarum Polysaccharides). Cutting of shoots stimulated growth of shrubs. Bushes cut into 3 shoots grew with larger number of shorter basal shoots, while the one-year shoots were the longest. The leaves of the cut bush were darker (L* = 39.8 and 41.2) and had a higher green index (42.1 and 44.8), in comparison to uncut bushes (L* = 37.3, SPAD = 43.5). It was also found that there is a significant correlation between the green index and the value of the parameter a* (r* = 0.92). Cutting of shrubs, especially into 3 shoots, reduced yielding however influenced increasing the size of the fruit.Pozycja Open Access Jakość owoców dwóch odmian winorośli oraz wpływ sposobu ich maceracji na barwę moszczu(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Ochmian, Ireneusz; Chełpiński, Piotr; Rozwarski, Rafał; Strzelecki, Roman; Pantecki, Paweł; Angelov, Ludmil; Stalev, Bojan; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Pracownia Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Winiarstwa, Uniwersytet Rolniczy w Plovdiv, Bułgaria; Katedra Winiarstwa, Uniwersytet Rolniczy w Plovdiv, BułgariaThe research was conducted in the years 2010–2011 at the Fruit Farming Laboratory of the West Pomeranian University of Technology in Szczecin. Two cultivars of grapevine were examined, Regent and Cabernet Sauvignon. The size of clusters and fruits, the content of extract and organic acid and juice yield of the grape must obtained were examined. The changes of grape must colour in the process of warm (20–22oC) and cold (7–10oC) maceration were evaluated. It was shown that the Regent cultivar was characterized by larger fruits. Grapes from this cultivar also had a higher content of organic acids, vitamin C and yielded more juice, compared to Cabernet Sauvignon fruits. However, a lower extract content was found in Regent cultivar fruits. It was also found that the temperature of grape must maceration affects its colour. The release of dark dye from grape skins occurred more rapidly during warm maceration. More substances which give wine its red colour were found in the grape must prepared from Cabernet Sauvignon fruits. The measurement performed on the last day of maceration of both cultivars under analysis, regardless of the temperature at which this process was conducted, revealed the highest value of the b* parameter which defines the blue colour.Pozycja Open Access Jakość owoców pięciu odmian persymony (Diospyros kaki)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2013) Chełpiński, Piotr; Yordanov, Anton; Dobrowolska, Agnieszka; Rozwarski, Rafał; Ochmian, Ireneusz; Katedra Ogrodnictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Sadownictwa, Uniwersytet Rolniczy w Plovdiv, Bułgaria; Katedra Ogrodnictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Ogrodnictwa, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieResearch was conducted in 2010–2011 at the Fruit Growing Department of the West Pomeranian University of Technology in Szczecin and at the Research Station of Agricultural University in Plovdiv, where, in the spring of 2006, persimmon trees of ‘Sharon’, ‘Moro’, ‘Jiro C24276’, ‘Kaki Tipo’ and ‘Hyakume’ cultivars were planted. The capacity of the fruits, soluble solids, organic acidity, Vitamin C, NO3 and NO2 contents as well as the fruit coloring were compared in Szczecin after harvesting. It was noted that Kaki Tipo and Hyakume cultivars were characterized by the largest fruits with an average mass greater than 220 g, and with a height and diameter 70 mm. The fruits were characterized by a wide range of skin colour: from bright yellow-orange to dark orange. The fruits of the ‘Hyakume’ cultivar were the brightest (L* 63.19) and contained the most yellow pigment (b* 63.54). Small contents of organic acids (0.37–0.67 g citric acid per 100 g of fruit), nitrates (1.0–4.5 mg 100 g–1) and a nitrites (0.15–0.30 mg 100 g–1). Fruits were characterised by large differences in vitamin C content from 41mg (‘Hyakume’) to 98 mg (‘Sharon’) per 100 g of fruit but similar values for the content of extract (16.6–17.4%).Pozycja Open Access The National Program for the Liquidation of Pesticide Waste Landfills, Successes and Unused Opportunities – Case Study from Poland(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Błaszak, Magdalena; Ochmian, Ireneusz; Department of Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, Szczecin, Poland; Department pf Horticulture, West Pomeranian University of Technology, Szczecin, PolandPrevious generations (50–70’s of the last century) left behind thousands of tons of toxic agrochemical waste (produced and stored for stock). Some of them have already been liquidated, but some have remained, because the costs of liquidation are enormous. In 2011, the national program for the liquidation of pesticide waste landfills ended (pesticide burial grounds with various chemicals types, organochlorine pesticides such as DDT, lindane, toxaphene, methoxychlor, heptachlor, α-HCH, β-HCH and phosphoroorganic pesticides, carbamate insecticides, dinitrophenols, phenoxyacids). The necessity of liquidation about 240 pesticide burial grounds (approx. 20 000 Mg obsolete pesticides) located throughout the country resulted from the obligations of Poland ratifying in 2008 the provisions of the Stockholm Convention on Persistent Organic Pollutions. The preparations and packaging were taken to the operated hazardous waste incineration plants. Debris and soil adjacent to the burial grounds were placed in hazardous waste landfills. After 6 years since the end of the national program for the decommission of burials, it is time for summarizing. Due to the fact that similar objects can be found in many countries around the world, analysis of the Polish case may be useful. The publication focuses not on the methods of utilization and statistical data, but on a critical look at the applied solutions, also presenting alternative solutions (mainly in situ and ex situ bioremediation), instead of storage.Pozycja Open Access Porównanie jakości owoców trzech odmian porzeczki czarnej (Ribes nigrum L.) w zależności od ich wielkości(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2013) Ochmian, Ireneusz; Dobrowolska, Agnieszka; Strzelecki, Roman; Kozos, Karolina; Katedra Ogrodnictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Ogrodnictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Ogrodnictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Ogrodnictwa, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe research was conducted in the years 2010–2012 at the Fruit Farming Laboratory of the West Pomeranian University of Technology, Szczecin. The study involved blackcurrant cultivars of ‘Ben Alder’, ‘Sofijewskaja’ and ‘Tisel’ and consisted in the comparison of their respective fruit size and firmness, chemical composition, colours according to the size of fruit. After harvest yield was immiedately divided into small (<13 mm) and large fruits (>13 mm). From among of researched cultivars ‘Tisel’ characterised the major fruits; the large fruits in total yield was 79%, and the average weight of 100 of these fruits was 205 g. It was found that the small fruits of all tested cultivars were firmer (212 G mm) and less susceptible to damage (101 G mm) than large fruits (71 G mm). Among the tested varieties the most firm fruits were of ‘Ben Alder’ (234 G mm). Small fruits were also characterised by a higher acidity (3.24 g), lower pH of juice (3.24) while a higher content of vitamin C (182 mg). Small fruits were also darker and had darker pulp – parameter L*.Pozycja Open Access Porównanie wzrostu i plonowania truskawki odmiany 'Aga' uprawianej w glebie zasobnej, nawożonej nawozami o zróżnicowanym składzie chemicznym(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2009) Ochmian, Ireneusz; Grajkowski, Józef; Popiel, Joanna; Strzelecki, Roman; Ostrowska, Krystyna; Katedra Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Sadownictwa, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe experiment conducted at Pomology Research Station of Szczecin Agricultural University permitted to compare the influence of the three fertilizers which have the differentiated chemical composition.

Poruszane są w nim podstawowe zagadnienia dotyczące morfologii roślin winorośli, sposo-bów rozmnażania i różne warianty prowadzenia i cięcia winorośli w celu otrzymywania jakościo-wych plonów winogron. Z informacji dotyczącej systemów technologicznych w produkcji win, ich pielęgnacji, jak i ewentualnych problemów, które mogą wyniknąć w procesie produkcji i przechowywania win będą mogli skorzystać również producenci wina.Pozycja Open Access Wpływ warunków siedliskowych na zawartość mikro- i makroelementów w liściach i owocach kilku odmian borówki wysokiej(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2013) Ochmian, Ireneusz; Katedra Ogrodnictwa, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieIn recent times, consumer awareness and interest in fruits from ecological farms have been on the rise. A range of requirements must be met to cultivate fruits in this way. The study compares the content of mineral components (micro- and macronutrients) in leaves and fruits collected from bushes of four cultivars cultivated conventionally and ecologically. The research was conducted in the years 2009–2011 at the Fruit Farming Laboratory of the West Pomeranian University of Technology in Szczecin. The macro- and micronutrient content in the leaves and fruits of four highbush blueberry cultivars cultivated in various soil conditions – in peat at an ecological plantation and in light soil (clayey sand) at a conventional plantation using synthetic fertilizers – was determined. Despite the fact that the soil was rich in phosphorus, potassium and magnesium at the conventional plantation and in potassium at the ecological plantation, the leaves were characterised by a low content of these elements. The leaves and fruits at the ecological plantation were characterised by a higher content of nitrogen, phosphorus, potassium, copper and iron, while the calcium content was higher at the conventional plantation. At both plantations, the nitrogen content in leaves was at a low level according to the standards, which was not confirmed by a visual assessment of bushes and their intensive growth.
