Studies on the Physiological and BiochemicalResponses of Cowpea ( Vigna sinensis) Seedling LeavesDamaged by CarmineSpider Mite (Tetranychus cinnabarinus (Boisduval))AbstractThis paper studied the chlorophyll and protein contents and theactivities of SOD, CAT, ASP, POD, PAL and PPO of Cowpea(Vigna sinensis) seedling leaves damaged by carmine spider mite(Tetranychus cinnabarinus (Boisduval)) in different pest densitiesand different days. The changes of POD, SOD isoenzymes andprotein were analyzed with PAGE and SDS-PAGE.In O?8 days, the SOD activity increased significantly (p |
