| 摘 要： | 以超短纤维突变体(Ligon lintless)及其野生型这一对遗传等基因系为材料,研究棉纤维伸长与内源激素含量及其相关酶活性的关系.结果表明,在野生型纤维快速伸长阶段,突变体却表现为:纤维中GA3初期的低含量、IAA的峰值出现时间推迟(迟6d)且明显低于野生型、ABA含量的快速降低时期出现迟(迟3d)且短(短6d)以...

| Abstract: | An appropriate level of endogenous phytohormones and expression of their relevant enzymes is crucial for normal development of fiber in Gossipium hirsutum L.Ligon lintless mutant with super-short fibers(5-8 mm in length) and its wild type with normal fibers(30 mm in length) were used to study the contents of endogenous phytohormones and related enzymes.ELISA revealed decreased and delayed accumulation of Gibberellic acid(GA3),Indole-3-acetic acid(IAA) and Zeatin riboside(ZRs) in Ligon lintless mutant as com... |
