Practice and Theory of gerbera cultivation in soilless media – The growing conditions in sandy-soil are almost the same as in Hydroponics, but more secure on. be used as a substrate for hydroponic culture of tomato and gerbera. 1. Introduction. In Crete there are about hectares of commercially grown greenhouse. PDF | To evaluate the performance (production and quality) of gerbera plants, cvs ‘Fame’, ‘Party’, ‘Regina’ and ‘Ximena’ were planted, in a heated plastic.

FLOWER AND GROWTH EVALUATION OF GERBERA CULTIVATED ON PERLITE IN AN OPEN HYDROPONIC SYSTEM
Performance of Gerbera Gerbera jamesonii Bolus cultivars under hydroponics. Performance of gerbera cultivars under hydroponics was evaluated at the Department of Pomology and Floriculture, College of Horticulture, Kerala Agricultural University, Vellanikkara during The main objective was to assess the suitability of gerbera cultivars to hydroponic culture and to compare the terbera, yield and vase life under hydroponics and pot culture.
Five gerbera varieties, viz. Observations were recorded on vegetative, floral and postharvest characters. Macro and micro nutrients of the plant samples were evaluated after the trial. The varieties exhibited wide variation gerbfra both vegetative and floral characters.
The plant growth in terms of height and spread was found to be greatly influenced by the variety and the plants of variety Intense were the tallest with more hydroponiv at flowering. The growth in terms of plant spread was the least when grown in hydroponic culture without media whereas it was the highest in pot culture. When interaction effect was considered plant spread of the variety Balance in hydroponics was comparable with that of plants in pot culture.
The gerbera varieties exhibited wide variation in leaf characters. The Balance recorded highest leaf length, breadth and area Leaf number was maximum in the variety Stanza The growing conditions were also found to have influence on leaf characters, and plants in pot culture recorded the maximum values. Significant positive correlation was observed between light intensity and vegetative characters namely, plant spread, leaf length, leaf area and number of lobes and negative correlation between leaf breadth and petiole length.
Gerbera varieties differed in the duration taken for flowering under different growing conditions. Balance was the only variety that flowered under all the three growing conditions.
There was considerable variation in the flower characters, viz. The highest value for flower stalk length These two stalk characters were considerably less in plants grown in hydroponic culture with and without media.
Significant variation was not observed in the flower and disc diameter among the varieties under different conditions. Maximum number of flowers The hydroponiv Balance produced 6.
Varietal differences were not significant with respect to the concentration of macronutrients like N, P, Ca and Mg in the plant, whereas K and S differed. The concentration of K and S was the highest in Balance 2.

Among the growing conditions, hydroponic culture with media was significantly superior to others, with respect to the concentration of K, Mg and S, whereas pot culture significantly enhanced the P and Ca concentration. The variety Hydropojic recorded highest K concentration 3. Variety Dana Ellen had the highest Cu and Mn concentrations The concentration of Cu, Fe, Zn and Mn were the highest In overall comparison between gerbera varieties and growing conditions with regard to hydropinic characters, plants in pot culture were found to be more vigorous in terms of plant height, spread, number of lobes, leaf characters, viz.
The variety Balance in hydroponics with and without media was comparable with that of pot culture and it was the only variety that flowered under all the growing conditions.
