Male sterility is very important in the utilization of hybrid heterosis in cotton, ＂Temian s - 1＂ , the steady thermo -sensitive male sterility,as a new type of male sterilities in cotton, its physiological and biochemical mechanism has not been well explored. By using the thermo - sensitive male sterility ＂D7＂ as materials, the activities of reactive oxygen species scavenger enzymes and the content of MDA of them were tested individually to study the relationship between the sterility and reactive oxygen species. The main results are as fo...
