摘 要 ：带有长节间基因eui水稻不论在苗期和抽穗期对GA3的敏感性均高于等位的Eui基因，尤其对茎部的第1和第2节间影响较大，属1-2节间伸长型。带有Eui基因则对第2和第3节间伸长影响较大，属2-3节间伸长型。带有eui基因的珍长保持系作为供体，将eui导入野败不育系二九南1号、二九青、V20以及矮败不育系协青早，使其穗伸出长度提高了82

Abstract:Rice with the eui gene for the elongated uppermost internode is more sensitive than that with the Eui gene to GA3 at seedling and heading stages. The first and Second internodes of the Plant with the eui gene and the second and third ones of the plant with the Eui gene are greatly affected by GA3, w
