摘要
利用光镜和扫描电镜对大风子科 9属 1 3个种的花粉形态进行了观察。花粉形状长球形或圆球形 ,除大风子属 (Hydnocarpus)萌发孔为三拟孔沟 ,其余均为三孔沟 ;外壁纹饰在不同属、同属不同种间表现出明显的多样化 ,基本上可分为粗网状、细网状、穿孔状、穴状4种类型。
The pollen grains of 13 species representing 9 genera of Flacourtiaceae were examined by light microscopy and scanning electron microscopy.These related genera have fairly similar in pollen shape (prolate-spheroidal) and tricolporate,though Hydnocarpus with indistinctly tricolporate.The pollen exine sculptures can be divided into 4 types:foveolate,finely reticulate,coarsely reticulate and perforate.Pollen morphology plays a certain role in the circumscription of among related families and different genera.
