| 摘 要： | 对耐抽薹材料Y58半大株采种法和小株采种法的采种效果进行了研究.结果表明,半大株采种法比小株采种法提高产量62.2%.主要是提早了开花期17 d;增加了一级和二级侧枝分枝数,比小株提高47.4%和45.8%,减少了无效分枝三级侧枝数55.3%;同时增加了一级和二级侧枝上结荚数,分别增加68.1%和99.6%.表明耐抽薹材料采用半大株采种是可行的.

| Abstract: | The effect of 2 seed production methods about late bolting Chinese cabbage germplasm Y58 had been researched.The result showed that "the maternal plant"could produce 62.2% more seed than "the small plant".The main reason is the blossom time of the former was 17 d earlier than the latter;The shoot number of the first and the second lateral shoots of the former was 47.4% and 62.2% more than the latter,the number of the third was 55.3% lower than the latter;The pod setting number of the first and the second lateral shoots of the former was 68.1% and 99.6% more than the latter at the same time.This shows that"the maternal plant" is feasible for late bolting germplasm. |
