Antioxidants which were used are -tocopherol and extract of red fruit) dissolved in acetone, ascorbic acid dissolved in water also. Seeds were stored at 70-80% relative humidity and 28-29C for 12 weeks. Periodically, viability and vigor were determined. Seed viability and vigor were estimated by percentage germination, speed of germination, T50, and Index of vigor. Seeds treated with -tocopherol 150 ppm showed the highest viability and vigor during the ageing period, while ascorbic acid 300 ppm also retarded the rate of ageing. Treating seeds with red fruits showed the highest of T50. The ability of -tocopherol, ascorbic acid and red fruit to reduce viability and vigor loss of stored cotton seeds may be due to their ability to inhibit lipid peroxidation

Email : [email protected] Program Studi Agrotekhnologi, Fakultas Pertanian UNSYIAH Banda Aceh.Email :[email protected], chilli grows at dry season, but only offers low price of the yield. To obtain high price of the yield, usually farmers grow this crop at out of season, i.e. wet season. Wet season, however, has more limiting factors to increase the yield, such as water logging. The aim of this study was to understand the resistance of plant to water logging. Seedlings at 21 days of age were planted in plastic container. The result indicated that full water logging and half water logging inhibited vegetative growth of chilly. However, the seedlings were survive until 3 week of logging. Full water logging caused horizontal growth of roots. Full water logging also caused increase of chlorophyl b, antocianin, and carotenoid, but decrease of chlorophyl a
