摘要： 用扫描电镜(SEM)对20个杏品种(种)花粉形态研究表明：应用临界点干燥技术干燥杏花粉，花粉粒大小在杏和西伯利亚杏种间差异不明显，品种间花粉大小差异较大。花粉粒外壁纹饰在种间和种内均有较大差异。通过聚类分析将供试20个品种(种)分为9类。

Abstract: The pollen morphology of twenty apricot (Armeniaca sibirica L.and Armeniaca vulguris L.)varieties (species) were evaluated with scanning electron microscopy (SEM).All the pollen samples were dried with critical point drying (CPD).The result showed that there were not significant differences in size of pollens between Armeniaca sibirica L.and Armeniaca vulguris L.but there were more significant difference in size of pollens among nineteen apricot varieties (Armeniaca vulguris L.).There were large differences in the pollen surface topography of twenty apricot varieties (species).Twenty varieties (species) can be classified into 9 types with cluster analysis.
