引进桃结果习性与果实品质的比较试验

Comparative Experiment on Fruiting Habits and Fruit Quality of Introducing Varieties Peach

以不同类型的9个引进桃品种为试材,对其雌蕊败育、坐果率和果实品质进行调查研究,结果表明:在阿拉尔垦区引进桃品种存在雌蕊败育现象,雌蕊败育率在1.46%~17.54%;总体单花芽雌蕊败育率高于复花芽,短果枝雌蕊败育率偏高;引进桃品种自花坐果率较高,异花授粉高于自花授粉;引进桃品种的果实品质存在显著性差异,‘春美’单果重最大,‘双喜红’可溶性固形物、可溶性糖、维生素C含量较高,品质最好。
