作者王近卫等从组织形态上研究了葡萄品种无核白的无核果形成机理,即:’无核白’同时具有自动单性结实和刺激单性结实的能力;花粉稔性正常;在盛花期,内珠皮、珠孔和胚囊发生异常;花粉管在子房内伸长较“康拜尔早生”品种差,但仍有60%以上的胚珠内观察到了花粉管;花后,胚乳核分裂异常,大部分结合子不分裂状态退化,少数结合子在分裂数次后,停止分化,退化成痕迹,不能形成正常的种子.’无核白’葡萄果实无核、皮薄、肉脆、 The author Wang Guowei and other from the organizational morphology of the seedless seedless grape seedless fruit formation mechanism, namely: ’non-nuclear white’ at the same time has the ability to automatically parthenocarpic and stimulate the parthenocarpic; pollen nocturnal normal; The inner pearl, perforation and embryo sac were abnormal. The pollen tube grew more in the ovary than the “Kang Baier early age” variety, but more than 60% of the ovules were observed pollen tube. After anthesis, endosperm Nuclear fission abnormalities, most of the unbound state of binders degradation, a few after the split number of binders to stop dividing, degenerated into traces, can not form a normal seed. ’Seedless White’ grapes without nuclear, thin, brittle meat,
