摘要: 研究了玉米Mo17核背景三种雄性不育细胞质(T、C、S)系及正常可育细胞质(N)系小孢子发育不同阶段花药组织的乙烯释放量,发现不育系小孢子败育前的一、二个时期内花药组织乙烯释放量显着增加。同时设计的乙烯利及其合成抑制剂外源喷施实验也表明了其对雄性育性的逆转效应。讨论了植物激素对玉米细胞质雄性不育性的调控作用。

Abstract: The contents of anther released ethylene of isonuclear alloplasmic lines on Mo17 nuclear background with three male sterile cytoplasm T,C,Tang Xu(S) and normal cytoplasm(N)line during the stage of microsporogenesis and development were studied.It was found that at the 1-2 stage(s)before the microspore abortion happened,the released ethylene contents from male sterile anthers were significantly higher than that from normal cytoplasm line.The study of exogenous application of plant growth substances demonstrated that ethrel could remarkably induce the abortion of microspore and pollen of male fertile materials.It was also found that the abortion stage of male sterile lines was partially delayed by the external application of CoCl 2 which is a kind of inhibitor of ethylene synthesis.The possible regulatory role of ethylene on CMS in maize was also discussed.

Key words: Maize, Cytoplasmic male sterility (CMS), Ethylene
