In this paper, pollination experiments and the effects of pollination tree on fruiting rate and seed-setting rate of Prunus armeniaca were studied by choosing grafting 'Weixuanl' as female parent and 4 different apricot tree as male parent. After the choosing suitable method. Pollen viability of 'Weixuanl' was evaluated by pollen germination test in vitro. It is feasibility to test stigma receptivity by the benzidine-H2O2 also. The conclusion is drawn as follows: The self pollination results showed that the self-pollination rate for 'Weixuanl' was 0. 84%(<6%) and * Weixuanl' were suggested to be a self-incompatible cultivar, The result indicated that most it need pollinating variety. Prunus armeniaca L. Cv. Katy is the best one a-mong them, The fructification ratio of cross pollination is 25. 88%; The viable pollen ratios of four test species were more than 70% and they could pollinate each other under natural condition, The pollen viability was 84.31% for 'Weixuanl', but pollen germination rate is low; The sucrose concentration has some effect on pollen germiration, which has a highest germina-tion rate at 10%; The stigma receptivity began enhancing in the time 3 h after anthesis. The stigma receptivity of 'Weixuanl' was around 4 days. Optimal pollination period lasted around 2 days.%以嫁接的2年生‘围选1号’为授粉母树,分别以‘围选1号’、‘优一’、‘凯特’、‘金太阳’4个不同的杏品种作为父本,进行授粉试验,研究不同授粉树对‘围选1号’结实率和坐果率的影响.同时,用花粉离体培养法测定其花粉生活力,并用苯胺一过氧化氢法测定了其柱头可授性.结果表明:‘围选1号’自花授粉坐果率为0.84％(＜6％),是自交不亲和品种；‘围选1号'以‘凯特'作为的授粉树效果最好,坐果率为25.88％；供试品种的花粉生活力都在70％以上.‘围选1号’的花粉生活力高达84.31％,但花粉的萌发力相对较低；不同蔗糖浓度对花粉发芽力有影响,其中以蔗糖浓度为10％的发芽力最高；柱头可授性在开花3h后可授性开始增强,可授性持续4d左右,最佳授粉期为开花后2d左右.
