Abstract: GA1+4 and IAA contents of Wild-type and BT-type cytoplasmic male sterile lines of rice and their restores(Zhen 97A.B;Hua 76-49A,B)were detected with indirect enzyme-linked-immunosorbent-assay(ELISA).It was found that GA1+4 contents in the penultimate lamina of Zhen 97 A and Hua 76-49A were lower than that of their restore lines since the beginning of spikelet-differentiation stage.From reduction-division stage,GA1+4 content in young panicle of Zhen 97A became lower than that of its restore line,while GA1+4 content in young pancile of Hua 76-49A was still similar to that of its restore line.It was also found that IAA contents in pancile and penultimate lamina of Zhen 97A were obviously decreased compared with that of their restore lines since spikelet-differentiation stage and the beginning of IAA deficiency in Zhen 97A was much earlier than that in Hua 76-49A.It was proposed that GA1+4 and IAA deficiency would be the main physiological reason in rice cytoplasmic male sterility.
