摘　　要：利用光学显微镜和扫描电子显微镜对变豆菜属15种植物的花粉形态进行观察。结果表明,变豆菜属15种植物的花粉大小为(28.51~54.29)μm^(12.23^28.98)μm,极轴与赤道轴比值(Polar axis/Equatorial axis)为1.48~2.46,具三孔沟。花粉粒赤道面观有近矩形、赤道收缩形、长椭圆形等类型,其中近矩形和赤道收缩形占多数;极面观为圆形或三角圆形。在扫描电镜下,其外壁表面纹饰为网状。我们研究结果支持在伞形科变豆菜亚科中,变豆菜属植物的花粉具有中等进化、比较进化的形态特征,花粉形态可为个别物种的分类处理提供孢粉学证据。The pollen morphology of 15 species of Sanicula was observed by light microscopy(LM)and scanning electron microscopy(SEM).The pollen size of 15 species of Sanicula was(28.51-54.29)μm-(12.23-28.98)μm,and the ratio of polar axis to equatorial axis(Polar axis/Equatorial axis)was 1.48-2.46 with a three-hole ditch.Views of pollen grains include near-rectangular,equatorial contraction,long ellipse etc.Among them,near-rectangular and equatorial contraction are the majority.Polar views are round or triangular.Under the scanning electron microscope,the outer wall surface is reticular.Our studies support that in the Saniculoideae(Apiaceae),the pollen of the genus Sanicula has moderately evolved and relatively evolved morphological features.The pollen morphology can provide palynological evidence in the classifying individual species.
