The pollen morphology from various evolutionary stages including the primitive, the intermediate and the evolved of 15 tea germplasm materials was investigated.

对原始型、过渡型、进化型共计15份茶树种质资源的花粉形态进行了观测。

Except for some differences in exine ornamentation and pollen size, there is no great evolutionary divergence among genera in pollen morphology.

总体来讲，花粉没有大的演化分异，只是表面纹饰和花粉大小有一定的差异。
