| 摘 要： | 利用外源抑制剂多效唑和穗萌抑制剂，对水稻不育系冈４６Ａ在不同地区进行不同浓度的喷施处理。结果表明，两种抑制剂均显著地降低了冈４６Ａ的芽谷率；其中穗萌抑制剂的效果优于多效唑，以喷施１５００ｐｐｍ穗萌抑制剂的效果最佳，芽谷率由６．３８％降至２．３８％，防治效果为６２．７％。同时发现不同地区施药浓度与芽谷率有一定差异。在本试验浓度范围内，外源抑制剂对杂交水稻繁殖制种产量，种子商品质量和播种质量无不良影响。在杂交水稻繁殖制种的乳熟末期施用外源抑制剂是防治穗萌的有效途径。

| Abstract: | The test of external inihibitory substance. Paelobutrazol and ear germination inhibitor with different dosage on rice G46A-line at different area was conducted. The results showed that the paelobutrazol and eargermination inhibitor can evidently reduce ear germination percentage of rice G46A-line. The concentration of 1500ppm ear germination inhibitor, which reduced 6. 38% to 2. 38% germination percentage, was the best treatment among them. It can not chang breeding quantity and breeding quality. |
