Abstract:

Three transgenic Bt cotton and their isogenic non-Bt cotton counterpart another non-Bt cotton cultivar were investigated to evaluate the potential risk of transgenes on the soil ecosystem. The activities of urease, catalase,and invertase were assayed during cotton growth . The results showed soil enzymes activities were affected by different cotton cuiltivars and growth stages.
