【摘要】 通过对8个组合205株杂种树的叶片和果实部分性状测量值的分析,探讨了苹果杂种树叶片与早果性的关系以及叶面积与果实大小的关系。结果表明,苹果杂种后代中结果早与结果晚的树叶片的许多性状差异极显著,结果早的树叶片的纵径、横径、叶柄长度、叶柄粗度、百叶鲜重、叶面积和叶片体积明显高于结果晚的树,结果早的树的叶片的叶形指数明显低于结果晚的树;杂种树叶片面积与果实大小相关性极显著,叶片面积大则果实重量也大。育种中可以利用叶片与早果性及果实大小的相关性关系对杂种苗进行早期选择,提高育种效果,加快育种进程。更多还原

【Abstract】 Through analysis the measuring results of some characters of leaf and fruit of 205 seedling apple trees from 8 cross combinations, the relationship between leaf and early fruiting character, between leaf area and fruit weight were discussed. The results show that the difference in some leaf characters between early fruiting tree and late fruiting tree is much marked. The leaf width?leaf length, length and thickness of leafstalk, weight per hundred leaves, leaf area and leaf volume in the early fruiting tree is much bigger than that in the late fruiting tree, but the leaf shape index of former is much smaller than that of the latter. The close correlation between the leaf area and the fruit weight is found. The larger the leaf area is, the heavier the fruit will be. The relativity between leaf and early fruiting character, and between leaf and fruit weight can be applied to early selection for the crossed seedling apple tree, to improve breeding effect and speedup the breeding course.更多还原
