摘　　要：通过光镜(LM)观察了四川柴胡属植物14种(变种)的花粉形态,结果表明:该属植物的花粉已经发生了明显分化,主要有菱形,椭圆形,矩形三种类型以及它们之间的过渡类型。最后分析了柴胡属植物的花粉进化趋势并探讨了种间亲缘关系。Pollen morphology of 14 species(varities)were examined under LM, It shows that the pollen morphology differentiates apparently, According to the shape of pollen, we may divide them into three main types: rhomboidal type, ellipsoidal type and retangular type. There are also some transition among the three types, At last, the revolutionary trends of pollen types are given and the affinity relationship is approached.
