Abstract
The importance of hydro-cultural growing is significantly increasing.We have been dealing with the hydro-cultural growing of cut flowers at the Department of Ornamental Plant Growing and Maintenance of Gardens at the College Faculty of Horticulture at Kecskemét College since 1988.We started our experiments by growing carnation in growing establishment without soil then we introduced other species of cut flowers and potted ornamental plants into our research work.
Highlights
Our aim was to examine the effect of Grodan and PUsponge media on the growth, the yield of flowers, the diameter of the flowers and the length of the stem concerning the species of carnation ‘Pink Castellaro’
In case of the hydro-cultural growing of carnation both the polyurethane-ether sponge and Grodan had a good effect on the growth of the plant, both are adequate as a plantation media but the stock grown in the sponge was higher
We managed to reach the average flower yield of 7–9 flowers per stem (Figure 1.) characteristic of the traditional chemo-cultural growing in case of hydro-cultural growing in polyurethane-ether sponge and in Grodan that is both are adequate plantation media for hydro-cultural growing
Summary
Our aim was to examine the effect of Grodan and PUsponge media on the growth, the yield of flowers, the diameter of the flowers and the length of the stem concerning the species of carnation ‘Pink Castellaro’. In case of comparing the species our aim was to examine the effect on the development of the plants, the yield and the characteristics of the flowers: the diameter of the flower and the length of the stem. The effect of the species on the flower diameter of carnation: Most of the species in the experiment reached or exceeded the parameters of 1st class products determined by the standards, minimum was 7.0 except for the values of 6,91 and 6,96 of ‘Candy’ and 6,87 and 6,89 of ‘Ondina’ average yearly flower diameter (Lévai & Turiné, 2005a). In case of the ‘Castellaro’ species ‘Pink Castellaro’ produced significantly larger flowers (Lévai & Turiné, 2005b)
