杏树开花坐果习性的研究

Blooming and Fruiting Habits in Apricot

试验以二花槽、凯特、金太阳、沙金红、骆驼黄、张公园6个品种的杏树为试材,分别对各个品种的开花物侯期、不同类型果枝的花朵败育率、坐果率以及落花落果规律进行了调查分析。结果表明,二花槽、金太阳、沙金红这3个品种的花期最早,易受晚霜危害;同一品种不同类型果枝的花朵败育率不同,以中、长果枝的花朵败育率较高,而短果枝及花束状果枝的败育率较低;供试品种中以沙金红总体败育率最高,不适宜普遍种植;以金太阳和凯特两个品种的花朵败育率较低,坐果率较高,适宜广泛种植。相关性分析结果表明,杏树的花朵败育率和坐果率成极显著负相关。
