| 摘 要： | 大白菜（ＢｒａｓｉｃａｃａｍｐｅｓｔｒｉｓｓｓｐｐｅｋｉｎｅｎｓｉｓＯｌｓｓｏｎ）冠－２９１花期自交授粉后，花粉管在柱头乳突细胞表面盘曲，乳突细胞中出现胼胝质反应。蕾期自交授粉能克服自交不亲和性，但受精作用，胚胎发育较冠－２９１×石－８５１迟缓，单果鲜重及种子数仅为后者的一半。电助授粉未见明显效果。

| Abstract: | After self pollination of flower stage,there was callose formation in papillary cells of stigma of Brassica campestris ssp pekinensis,Guan-291.The pollen tubes couldnt enter the stigma.Self pollination at bud stage could breek self incompatibility,but fertilization and embryo development were slower than Guan-291 ×Shi-851.The weight per fruit and number of seed were less half than the later.Electric aided pollination hadnt significant effect. |
