Viability rice seeds with different levels of antioxidants

Total content of anthocyanidin glucosides varies greatly among different black varieties (79.5–473.7 mg / 100 g) and red rice (7.9–34.4 g). Shown up to 20 times higher antioxidants in varieties, compared with white grain, as well their 45 antioxidant activity many other crop. In terms content, is not inferior even such well-known sources blueberries currants, but much cheaper. The role phenolic acids substances increasing adaptability various stresses considered. presence glucoside also useful for the plants themselves at cellular level, normalizing metabolic processes response unfavorable abiotic influences, thereby stress viability seeds . objectives study were identify germination rate groups ripeness, color pericarp, shape weight caryopsis. Seeds stored uncontrolled temperature conditions three years. Every year, a all was carried out. grains each variety placed Petri dishes repetitions germinated thermostat 29° C 7 days, after which percentage calculated. Our research showed high varieties. Them significantly exceeded white-grain caryopsis on second third years storage. If during first year differences between most are reliable, then vitality groups.
