    The aim of the study conducted in the years 2008–2009 was assessment of the effect of growing media on rooting of apical and leaf-bud cuttings of hairy columnea (Columnea hirta). Medium components included sphagnum peat, perlite and zeolite in the following variants: 1. deacidified sphagnum peat, 2. zeolite, 3. peat with zeolite 3:1 v/v, 4. peat with zeolite 1:1 v/v, 5. peat with zeolite 1:3 v/v, 6. perlite, 7. peat with perlite 3:1 v/v, 8. peat with perlite 1:1 v/v, 9. peat with perlite 1:3 v/v. After 6 weeks of rooting, the number of developed roots and their length, the number of roots longer than 3 cm, and also the number of offshoots developed by cuttings. Apical cuttings developed larger and more complicated root system than leaf-bud cuttings. The plants that were rooted in media with the addition of zeolite or perlite (25–50%) produced many roots. The number of long roots were the biggest in the medium peat + zeolite 3:1 v/v.

    Experiments which determined the influence of salinity and medium on the growth, development and quality of two yarrow species were conducted in the years 2008–2009. Achillea millefolium and Achillea filipendulina seedlings were sown in September, 7 months before the beginning of the experiments constituted the research material. Young plants in their vegetative phase were planted before April 10 in five substrates – deacidified peat was the first substrate; 10, 20 and 30% of zeolite was added to the three next ones, respectively, and a mixture of acidic peat and mineral soil 1:1 v/v constituted the last substrate. The Azofoska fertilizer was used at a dose of 5 g dm–3. 3 weeks after planting when the root system regenerated, the plants began to be watered with a NaCl solution with EC 6.3 mS cm, obtained by adding 3.4 g of NaCl to 1 dm3 of water. The salinization was performed for four consecutive weeks, once a week. For the fernleaf yarrow was used 300 ml, and for the common yarrow was used 500 ml of the working liquid per pot. The amount of the working liquid depended on the size of the pots. The salinization process was ended after phytotoxicity symptoms occurred on plants. It was found that the use of salt slightly stimulated the growth of the common yarrow and also increased the mass of the above-ground parts. Poorer and delayed flowering of plants treated with the NaCl solution was observed for the fernleaf yarrow. The partial browning and drying of shoot tips was observed in both species, which slightly reduced their decorative value.

    Aim of the study was to evaluate the content of available nutrients contained in the substrates with municipal sewage sludge, the peat, and in a base of coconut fiber in the cultivation of ornamental plants. Experiments were conducted in the years 2005–2007. They using six horned violet cultivars (Viola cornuta L.) from Patiola F1 group and four substrates: I – sphagnum peat, II – substrate from peat and compost 1 (1:1 v/v), III – substrate from peat and compost 2 (1 : 1 v/v), IV – coconut fibre. Compost 1 was prepared using municipal sewage sludge (35%), potato pulp (35%) and straw (30%). Compost 2 was prepared using municipal sewage sludge (35%), potato pulp (35%) and sawdust (30%). Composts after 10 months of composting were used in the research. It has been shown that composts made from municipal sewage sludge are rich in available forms of nutrients and the plants grown in them grow and develop properly without the need for top dressing fertilizer. Relatively high concentrations of NaCl and Cl content in media supplemented with sewage sludge compost does not adversely affect the development of the group violets F1 Patiola.
