    Eucomis species are a relatively new pot plants with potential for expansion. The aim of the study was to compare the growth, flowering, bulbs yield and macronutrients content of three species: Eucomis autumnalis, E. bicolor and E. comosa. The experiment was conducted in 2013 and 2014 in a greenhouse. The bulbs were planted in 18 cm diameter pots containing a deacidified peat, supplemented with a fertilizer Hydrocomplex. Of all the species tested, E. autumnalis had the least leaves, flowered earliest and produced the highest number of adventitious bulbs. E. bicolor had the highest number of leaves, produced longer and wider inflorescences and the least number of adventitious bulbs as compared to the other two species. E. comosa was characterized by the largest diameter of adventitious bulbs and the highest potassium content in the leaves. The analysis of the macronutrient composition of three Eucomis species showed that the leaves contained more nitrogen, phosphorus, potassium, magnesium and calcium than the bulbs.

    The aim of the studies in the years 2009–2010, carried out in the climate conditions of Szczecin, was to compare the morphological traits, the course of flowering and the increase in number and weight of bulbs of four species: Arabian starflower (Ornithogalum arabicum L.), Sun star (Ornithogalum dubium Houtt.), Giant Chincherinchee (Ornithogalum saundersiae Bak.), and Chincherinchee (Ornithogalum thyrsoides Jacq.). The bulbs were planted in soil after the 10th of May, and harvested in the first decade of October. The investigated species of Ornithogalum were found to differ significantly in their morphological traits, flowering and bulb yield. Field-grown O. arabicum, O. saundersiae and O. thyrsoides flowered and produced adventitious bulb each year. Among the cultivated species, O. saundersiae was characterized by the longest flowering period, it had the longest leaves and inflorescence scapes, and its inflorescences contained the highest number of flowers. The parent bulbs of O. saundersiae produced also the greatest number of adventitious bulbs. The O. dubium plants did not produce inflorescences or adventitious bulbs in either year of the study.

    Oceniono wpływ wielkości cebul na przebieg kwitnienia, jakość kwiatostanów i plon cebul śniedka Saundersa (Ornithogalum saundersiae Baker) uprawianego w nieogrzewanym tunelu foliowym. W doświadczeniu wykorzystano cebule o obwodzie: 12–14, 14–16, 16–18, 18–20, 20–22 i 22–24 cm. Z cebul o obwodzie 22–24 cm i 20–22 cm otrzymano rośliny, które kwitły najdłużej i miały szersze kwiatostany, o większej liczbie kwiatów. Rośliny, uzyskane z cebul o obwodzie 12–14 cm i 14–16 cm, rozpoczynały kwitnienie średnio o 15,7 dnia później; wytworzyły najmniej kwiatów w kwiatostanie. Najwięcej cebul przybyszowych otrzymano z cebul o największym obwodzie. Najwyższy współczynnik wagowy odnotowano dla cebul uzyskanych z cebul matecznych o najmniejszym obwodzie.

    Aim of the experiment carried out in 2008–2009 was to assess the effect of the kind of twin scales and seaweed extracts on yield of adventitious bulbs of Arabian Star Flower (Ornithogalum arabicum L.). The twin scales were excised from the outer and inner of the parent bulb. The twin scales were soaked for 30 minutes in 0.2% solution of AlgaminoPlant and Goëmar Goteo containing extracts of algae Ascophyllum and Sargassum. The research showed the number of adventitious bulbs formation was greater when twin scales were excised from the outer of the parent bulb. The adventitious bulbs formed from outer twin scales had a higher fresh weight, circumference, number and length of roots. The seaweed extracts used stimulated the number and length of roots of adventitious bulbs.
