Hydration accomplished by soaking the stored seeds original weight was effective in controlling deterioration of seeds stored under high humidity and high temperature conditions (100% RH and 400 C). Hydration dehydration treatments with dilute solutions of a number of chemicals also showed significant beneficial effects with 18 months old seeds. Further, coating the seeds with kaolinite paste made with dilute solution (2 x 10-5M) of p-aminobenzoic acid and kept closed for 15 min before drying effectively controlled the physiological deterioration in greengram seeds.
