摘要
应用不同浓度的赤霉素 (GA3)溶液在苗期处理CHA 1、特华占 (原种 )、日本晴、矮脚南特等 4个材料 ,研究它们对GA3反应的敏感性。结果表明 ,经空间诱变的矮秆突变体在苗期对GA3的反应敏感 ,但与已知带sd 1基因的籼、粳稻代表品种矮脚南特、日本晴敏感性有差异。进一步的遗传分析表明 ,控制CHA 1的一对隐性矮秆基因与sd
A dwarf mutant CHA-1 obtained from a high-plant rice cultivar Tehuazhan by space inducement, and its response to gibberellic acid (GA 3) at seedling stage was studied. CHA-1 was sensitive to GA 3, but it was different to Nipponbare(japonica) and Aijiaonante(indica) (both with semidwarf gene sd-1) in sensitivity to GA 3. Further genetic analysis revealed that the mutant was controlled by a dwarf gene which was non-allelic with dwarf gene sd-1.
