| Abstract: | Researches showed that transgenic Bt hybrid cotton CCRI29 had higher contents of chlorophyll and Indole 3 acetic acid, lower contents of MDA, higher activity of SOD and CAT enzyme in the cotton seedling stage, which made the cotton seedling more vigorous, lower membrane lipid peroxidation and stronger resistance to light, temperature and water stresses. It had higher contents of MDA and ABA, higher activity of POD enzyme in the middle late season. Higher photosynthetic rates and more nitrogen supply in total growing period. Experiment showed that the best planting date in north China plain under mono cultured is April 22 and the planting density under the middle level of applying fertilizer and water management for CCRI 29 are is 52500 plant/ha. CCRI29 was not sensitive for chemical control, so chemical control in the seeding stage was just depend on site. |
