鲜食杏裂果与果实部分性状的相关性研究

在北京市农林科学院林业果树研究所杏育种圃内,以同一杂交组合的实生后代中连续多年有较多裂果现象的结果单株的果实为研究对象,其他未裂果单株的果实为对照,比较果实的单果质量、可溶性固形物含量和果实发育时间,并进行统计分析,结果表明,鲜食杏裂果单株平均可溶性固形物含量高于不裂果单株,果实平均单果质量和发育时间小于不裂果单株,但各指标差异均未达到显著性水平,即鲜食杏裂果与果实大小、发育时间和可溶性固形物含量等性状无明显相关性。

Studies of the Correlation between Fruit Cracking and A Few Fruit Characters of Apricot(Prunus armeniaca L.)

In breeding nursery of apricot in the Beijing's institute of forestry and pomology,there are two different phenotypes,cracking fruit and normal fruit,in the progeny of the same cross combination.A few fruit characters such as the fruit size,content of soluble solids,and fruit development days were compared between cracking fruits and normal fruits.The content of soluble solids of cracking fruits picked from cracking fruit trees are higher than those from normal trees,whileas average individual fruit weight and fruit development days are less,but the difference of all the index is not significant.
