Abstract:
Four melon (Cucumis melo L.) cultivars were tested for salt tolerance at germination, seedling growth stages, and plant maturation. 'Noy Amid' was the most tolerant during germination, achieving 56% germination in 15,000 mg/l NaCl solution. However, this cultivar and 'Eshkolit Ha 'Amaqim' were relatively sensitive during the first 4 days' growth of the radicle and the hypocotyl, and the first 3 weeks' development of the seedling. Their yields were reduced under saline as compared with non-saline field conditions. In contrast, 'Honey Dew' and 'Rochet' had little or no germination in 15,000 mg/l NaCl but showed salt tolerance during seedling growth stages. Yield of 'Honey Dew' was unaffected by saline field conditions, and that of 'Rochet' was not significantly reduced from the non-saline control. Thus, selection for salt tolerance in melons appears feasible during early vegetative growth stages but not during germination. © 1984 Springer-Verlag GmbH & Co. KG.
