| Abstract:
Seven clones of water spinach have been developed from seeds by means of micropropagation. These clones were cultivated in hydroponics with nutrient-film-techniques in recirculating nutrient solution in greenhouse. Mean temperatures ranged from 22 to 26°C and PAR was between 17 and 122W m-2. Clones have been distinguished by shoot number per plant, leaf number per shoot and shoot length. Leaf shape and area were botanical characteristics for each clone. The best performance for intensive cultivation clone 209 exhibited. This clone formed about 6 shoots with a uniform length of 20 cm and 8 leaves per shoot. Shoots were harvested in 2-week-intervals. In total, 9 times in this cultivation period, a fresh weight of 25 to 52 g per plant could be harvested. | |
