中文摘要：

以北京“龙泉雾”香白杏为试材，研究不同结果枝的花发育状况及采用不同杏品种人工授粉对香白杏坐果率等方面的影响。结果表明：香白杏花束状果枝和短果枝上完全花比例和花粉发芽率较高，花发育质量较好，推测其坐果较好。香白杏自花授粉坐果率较低，仅为2．5％，采用其它品种为其授粉可明显提高坐果率，利用“金太阳”、“葫芦杏”为其人工授粉，香白杏坐果率更可高达12．8％和12．3％，因此推荐其在实际生产中作为“龙泉雾”香白杏的授粉树。

英文摘要：

Taking ＇ Longquanwu＇ of Armeniaca vulgaris L. as test rnaterial,a series of surveys and experiments about flower development and fruit setting were performed. The results showed that the percentage of perfect flower and pollen germination in the short fruit branches and the bouquet branches were high, indicating a good result of fruit setting. Armeniaca vulgaris L. was self-unfruitfulness with a fruit-setting percentage of 2. 5 %. With pollens of ＇Jintaiyang＇ and ＇ Huluxing＇ pollinated for Armeniaca vulgaris L. ,fruit-setting percentage reached 12. 8% and 12. 3% ,thus they could be used as pollinizers for Arrneniaca vulgaris L.
