摘　　要：对新疆库车小白杏的授粉生物学特性进行研究表明:(1)库车小白杏完全花比例为39.35%,不同果枝类型的完全花比例大小为中果枝﹥花束状果枝﹥短果枝﹥长果枝。(2)自花授粉试验表明,库车小白杏为自花不实类型,自然授粉结实率为5.85%。(3)疏花和液体授混合花粉可以明显提高库车小白杏坐果率,疏花50%和70%是自然授粉结实率的1.31倍和1.71倍;液体授混合花粉是自然授粉结实率的1.91倍。The pollination biology of KuChe little white apricot shows that complete flower ratio of KuChe little white apricot is 39.35%, the complete flower ratio on different fruit branches is different, medium branch is higher than bouquet spur, short pod-branch and long branch. From the pollinating test we find that KuChe little white apricot is self-unfruitful, its natural- pollination fruit-setting ratio is 5.85%. Flower thinning and cross- pollination can make the fruit-setting ratio higher than natural- pollination, the fruit-setting ratio of 50% and 70% flower thinning is 1.31 times and 1.71 times than natural- pollination, liquid supplementary pollination is 1.91 times than natural- pollination.
