以水稻同核异质体雄性不育系WAV_(41)A，KVV_(41)A和保持系V_(41)B为材料，用酶联免疫检测法（ELISA）测定了幼穗和倒二叶鞘的内源激素IAA、GA_(1＋3＋4＋7)含量。结果表明：同核异质体的两种雄性不育系幼穗分化过程中，幼穗IAA、GA_(1＋3＋4＋7)含量低于保持系，从而提示雄性不育与内源激素（尤其是IAA）的亏损有关。两种胞质不育系IAA、GA_(1＋3＋4＋7)的含量WAV_(41)A低于KVV_(41)A，WAV_(41)A内源激素亏损时期早于KVV_(41)A；倒二叶鞘两种激素的含量WAV_(41)A高于KVV_(41)A和V_(41)B；KV_(41)A内源激素生理代谢与栽培稻V_(41)B有相似之处，说明了WAV_(41)A和KVV_(41)A在其内源激素的代谢上有明显差异。
In the present study, young male and female SSR male sterile lines, WAV_ (41) A, KVV_ (41) A and maintainer line V_ (41) B, Of endogenous hormones IAA, GA 1 (+3 +4 +7) content. The results showed that the IAA and GA 1 + 3 + 4 + 7 contents of panicles were lower than those of maintainer lines during panicle differentiation of two male sterile lines with the same nuclear heterozygosity, which suggested that male sterility and endogenous hormones (especially IAA) Loss related. The content of IAA, GA 1 + 3 + 4 + 7 in both CMS lines was lower than that of KVV 41 A, and the WAV 41 A stage was earlier than KVV 41 A. The content of hormones WAV_ (41) A was higher than that of KVV_ (41) A and V_ (41) B; the physiological metabolism of endogenous hormones of KV_ (41) A was similar to that of cultivated rice V_ (41) B, 41) A and KVV_ (41) A have significant differences in the metabolism of their endogenous hormones.
