| 摘要: |
| 对8个假单性结实类型(种子败育型)无核葡萄品种的胚发育进行的解剖和切片检查表明,种子败育型品种合子胚的发育与有核品种基本相似,但合子胚形成的能力、胚败育时发育的程度以及浆果成熟时胚珠及胚残留的程度均存在很大差异,同一品种胚的发育和败育都不是同步的。 |

| Abstract: |
| The results of morphorlogical and anatomical observation on the embryo development in the 8 cultivars indicated,all the 8 cultivars belong to stenospermocarpy.They have alike stage with seed-bearing grapes in early de- velopment of embryo.But percentage of the embryo developed,level of the embryos development and of ovule remnant in the berries riped were different. At one time development and abortion of the embryo were not cuychronous in same culivars too. |
| Key words: seedless grape embryo development |
