7种豆科植物花粉形态的研究

Pollen Morphological study on 7 Apecies of Fabaceae,

本文根据我国７种豆科植物的花粉形状和纹饰特点，将其分为两种类型，即近球形──扁球形、穴状纹饰花粉和长球形、网状纹饰花粉。作出了花粉形态分种检索表，并对７种植物的演化关系进行了初步讨论。

The pollen morphology of 7 species of Fabaceae was observed.According to the pollen shape and the characters of exine ornamentation,the pollens of the 7 species can be di- vided into two types :(1 )sub-globosus-depresso-globosus、foveolae ornamentation;(2 )Long-globosus、areolatus ornamentation.The pollen morphological key of the 7 species is suggested in this paper based on the characters of pollen grains ,and evolution- al relationship of the 7 species is preliminary discussed.
