Abstract： 选取含有诱变的长穗颈基因eui1、eui2和野生型基因Eui的水稻(Oryza sativa L.)协青早保持系3个等基因系,通过供试植株在不同生育期的GA1和ABA含量测定及喷施GA合成抑制剂,并辅之器官删除试验等方法,探索长穗颈水稻上部节间伸长的生理机制.结果表明,在抽穗期,含eui1的协青早保持系XeB1幼穗和剑叶里的GA1含量显著增加,分别约为对照协青早B的16倍和3.4倍,其GA1/ABA比值也明显增加;含eui2的XeB2幼穗和剑叶里的GA1含量显著提高,但仅在剑叶里GA1/ABA比值明显增加,其幼穗内的GA1水平显著低于XeB1.GA合成抑制剂S3307处理使XeB1和XeB2的株高生长均受到严重抑制.删除幼穗使XeB1最上节间伸长的受抑程度远大于XeB2和XB.由此推测,在抽穗期,eui1能使水稻自身产生GA1,高含量的GA1诱导了长穗颈水稻最上节间的剧烈伸长;在促进最上节间的伸长方面eui1强于eui2.图5表1参12
