| 摘 要： | 以种子败育型葡萄火星无核、康能无核为试材,系统研究其胚发育及败育的细胞学进程,分析胚乳败育与胚败育的关系。结果表明,种子败育型无核葡萄与有核葡萄的胚均能发育到球形胚阶段,但不同品种发育到该阶段的时间不同,火星无核在花后28~37 d处于球形胚阶段,康能无核在花后31~40 d,有核葡萄白香蕉的球形胚阶段是花后28~40 d,随后无核葡萄的胚逐渐败育,而有核葡萄的胚历经心形胚和鱼雷形胚阶段,最后发育成熟。种子败育型葡萄胚乳败育均早于胚败育,可能是胚败育的直接原因。火星无核、康能无核胚挽救适宜取材时期分别在花后34 d和花后40 d。 |

| Abstract: | Stenospermocarpic grapes 'Mars Seedless' and 'Centennial Seedless' were taken as materials to study the processes of embryo development and abortion and analyze the relation between embryo abortion and endosperm abortion.The results showed that embryoes of both stenospermocarpic grapes and seeded grapes can develop to globular embryo stage.But the time developed to this stage varied among different cultivars.The 'Mars Seedless' was from 28 days to 37 days after florescence and the time of 'Centennial Seedle... |
