These experiments were conducted to investigate the biochemical and morphological characteristics of aged and non-aged seeds for increasing seed viability. Optimum duration of artificial aging treatment to test aged seeds as observed; 4 days for Chinese cabbage; and 5 days for radish seed. Sinapine leakage in Chinese cabbage and radish were increased with increased with increased treatment duration from 1hr to 8hrs. Aged seeds had higher sinapine leakage after soaking in water than that of the non-aged seeds. Aged seeds of Chinese cabbage had bigger leakage in amino acid and potassium content than non-aged seeds. For total sugar content of Chinese cabbage, aged seeds were increased as soaking time also increased, while non-aged seeds were not. The kind of leaked sugar from aged seeds consist of glucose, fructose and sucrose for Chinese cabbage. Cell ultrastructure of aged seed surface in Chinese cabbage was observed irregularly cracked and breakdown with holes in cotyledon surface, while surface tissue of non-aged seed was well arranged and compacted. Aged red pepper seed had higher content of saturated fatty acid (palmitic acid), but lower content of unsaturated fatty acid (oleic acid and linoleic acid) than that of non-aged seeds. Banding patterns of seed storage protein using SDS-PAGE in aged seeds of Chinese cabbage and radish were characterized by the disapperance of major band as compared to normal seed of crops.
