不同类型品种花生叶片的CAT活性变化趋势一致 ,均于花后 2 7d达到高峰 ,花后 6 7d之前小粒型 >大粒型 >中粒型 ,之后为大粒型 >中粒型 >小粒型 ;POD活性于花后 37d和 77d达到高峰 ,酶活性表现为中粒型 >小粒型 >大粒型 ,且中粒型品种变化剧烈 ;SOD活性表现为大粒型 >中粒型 >小粒型。荚果发育前期 ,CAT和SOD活性高 ,发育后期POD活性高。大粒型品种保护酶SOD起主要作用 ,小粒型品种POD和CAT起主要作用 ,中粒型品种介于两者之间
The CAT activity of different types of peanut leaves showed the same trend, both reaching the peak at 27 days after anthesis, and were small> large> medium, Reached its peak on the 37th day and the 77th day after anthesis, and the enzyme activity showed medium grain size> small grain size> large grain size, and medium grain variety changed drastically. SOD activity showed large grain size> medium grain size> small grain size. Early pod development, CAT and SOD activity, POD activity in the late development stage. SOD, a major grain-type variety, played a major role. POD and CAT, the small grain-type cultivars, played a major role. Medium-grain varieties ranged between the two
