对109个籼、粳、糯稻辐射矮杆突变体及其46个原种和对照进行赤霉素处理,表现为敏感与不敏感两种类型;有8个突变体经复测同雪河矮早一样均不敏感;有些非sd-1基因的突变体或矮秆品种对赤霉素亦反应敏感;同一矮杆基因在籼、粳不同类型品种中,对赤霉素反应不一样。从而说明:“具有sd-1基因的矮杆品种,其株高对赤霉素均反应敏感;而矮生基因与sd—1非等位的矮杆品种,其株高对赤霉素反应却不敏感”这一前人研究的论断值得商榷和进一步验证。
A total of 109 indica, japonica, glutinous rice radiation dwarf mutant and its 46 species and the control of gibberellin treatment showed two types of sensitive and insensitive; 8 mutants were tested with the snow short river The same dwarf gene was not sensitive to gibberellic acid in different varieties of indica and japonica. Thus, “the dwarf strain with sd-1 gene is sensitive to gibberellic acid, while the dwarf strain with sd-1 is not allelic to gibberellic acid Insensitive ”the predecessor’s research is arguable and further verified.
