通过观察雌花柱头开放过程中的形态变化,研究了雌花套袋、切柱头和聚乙烯醇封柱头处理核桃无融合生殖坐果情况;比较了无融合生殖坚果与自然授粉坚果果实性状的差异。结果表明:套袋、切柱头和聚乙烯醇封柱头处理的无融合生殖生理落果期的座果率分别为42.5%、26.7%、46.7%,套袋和聚乙烯醇封柱头处理的座果率差异不显著,且均显著高于切柱头处理的座果率;“绿岭”核桃的无融合生殖坚果的纵径、横径、侧径、三径均值、单果质量、种仁质量、出仁率与自然授粉,两者间差异显著。
By observing the morphological changes during the opening of stigma, the conditions of apomictic fruit walnut, bagged stigma and poly (vinyl alcohol) stigma were studied. The differences of fruit characters between apomictic and natural pollination nuts were compared. The results showed that the rates of fruit set in bagging, stigma and polyvinyl alcohol stigma treatment were 42.5%, 26.7% and 46.7%, respectively. The fruit set rate of bagging and polyvinyl alcohol stigma treatment The difference was not significant, and all were significantly higher than those of the first stigma treatment. The vertical, horizontal, lateral, mean of single diameter, single fruit mass, seed quality, Kernel rate and natural pollination, the difference between the two significant.
