CYTOLOGICAL OBSERVATION ON THE FERTILIZATION AND EMBRYO DEVELOPMENT OF A CROSS BETWEEN RICE(ORYZA SATIVA)AND SORGHUM(SORGHUM VULGARE)-文献传递-植物通论文库

摘要：本研究以石蜡制片方法观察高粱花粉管伸入水稻胚囊后,释放精子,两亲性细胞融合过程及胚胎发育情况。观察表明:高粱精子能够与水稻卵子融合形成合子。少数合子(占0.44%)进一步分裂,发育成幼胚组织。本文对远缘杂交性细胞融合的潜在价值,促进杂种胚胎继续发育的方法及某些远缘杂种形成的机制进行了探讨。

Abstract:The fertilization and embryo development of a cross between a rice(Oryza sativa)variety Yinfang and a Sorghum(Sorghum vulgare)varietyHengjiali were studied from 1980 through 1982 in Beijing.The resultsobtained indicated that the pollen tubes of sorghum could enter thetissue of style,of rice,reach th
