摘　　要：The results of this experiment indicats that compared with the control cultivar Yumai 8,Yumai 36 has higher activities of SOD and CAT, lower content of MDA and longer life span of functional leaves during the seed filling stage.The contents of proline, chlorophyll and protein were higher than check, but the water content of leaves was lower. New cultivar Yumai 36 has faster seed filling rate ,longer filling period and higher yield .The results of this experiment indicats that compared with the control cultivar Yumai 8,Yumai 36 has higher activities of SOD and CAT, lower content of MDA and longer life span of functional leaves during the seed filling stage.The contents of proline, chlorophyll and protein were higher than check, but the water content of leaves was lower.
