主枝上枝组直立与下垂对‘岳冠’苹果品质的影响

Effects of Vertical and Pendulous Branche Groups on the Fruit Quality of‘Yueguan’Apple

本试验以‘岳冠’苹果为试材,研究不同方向结果枝组对果实品质的影响。结果表明,下垂枝组的单果质量、果型指数、可溶性固形物和固酸比均高于直立枝组的;下垂枝组的果实色差值(L、a、b)均高于直立枝组的。因此,在‘岳冠’苹果生产中,应多培养和保留下垂结果枝组上的果实。

In this experiment,‘Yue Guan’apple was used to study the effect of fruiting branches on the fruit quality in different direction.The result showed that fruit mass,fruit figure index,soluble solids and solids acid ratio of pendulous branch group were higher than those of vertical branch group;fruit color difference values(L,a,b)of pendulous branch group were higher than those of vertical branch group.Therefore,in the production of‘Yueguan’apple,more fruits with drooping fruiting branches should be cultivated and retained.
