摘要
Abstract
[Objective] To determine the catalase activity in watermelon during its different growth periods, so as to lay experimental basis for studying its metabolic changes and growing vitality at different periods. [ Method] Catalase was extracted from watermelon seeds during its ger-minating period, seedling period, seedling formation period, cotyledon differentiating period and adventitious bud growing period, and then the eatalase activity was detemtined with UV spectrophotometer. [ Result] The catalase activity in watermelon was the highest during the germina-ting period, while the lowest during the seedling formation period, the catalaac activity at different growth periods decreased in the order of ger-minating period > cotyledon differentiating period > seedling period > adventitious bud growing period > seedling formation period. The cat-alase activity in watermelon seedlings was gradually decreasing during its normal growth period, and it was also decreasing during the growth period of adventitious buds. [ Conclusion] The experiment supplied a method for determining the eatalase activity in plants, and also laid foun-dation for studying the antioxidant capacity of organisms under natural environment.关键词
