摘要
采用高效液相色谱法测定了烟草细胞质雄性不育系及其相应保持系花蕾发育过程中IAA,GA3,ZT及ABA4种内源激素含量的动态变化。结果表明,从小花蕾→中花蕾→大花蕾,烟草雄性不育系花蕾中IAA和ZT含量都比相应保持系的高;而不育系花蕾中GA3和ABA含量都比保持系的低。据此认为烟草花蕾内源激素含量的变化与雄性不育的发生有密切关系。
The dynamic changes of the indole acetic acid （ IAA）, gibberellin （ GA3 ）, zeatin （ZT） and abscisic acid （ABA） contents in flower buds of tobacco cytoplasmic male sterility （CMS） and homolog maintainer lines were determined by high-performance liquid chromatogram. The results showed that from small bud →middle bud→ big bud, the content of IAA and ZT in CMS buds were higher than in maintainer line buds. While the content of GA3 and ABA in CMS buds were lower than in maintainer line buds. It was suggested that the changes of endogenous hormone contents were closely related with the occurrence of cytoplasmic male sterility.
