Maintenance of seed vigour and viability of salt to lerant and susceptible cotton varieties using preservatives and chemicals
Abstract
Seed viability of six cotton (Gossypium hirsutum L.) strains differing in salt tolerance was measured both in control and different seed treatments. It was found that bleaching powder treated seeds survived the most. Linoleic and linolenic acid composition was measured and it was found that unsaturation of fatty acids was greater in salt susceptible varieties. It was also seen that salt susceptible varieties lost viability sooner due to peroxidation of unsaturated fatty acids, and greater the unsaturation, greater were the chances of peroxidation. Vitamin E, an anti-oxidant, which prevents peroxidation of unsaturated fatty acids, was found to be in greater amounts in salt tolerant varieties, with greater viability.
