摘　　要：应用扫描电镜(SEM)和电子计算机,本文作者对我国的5属21种、1变种木通科植物以及大血藤科植物的花粉形态进行了深入观察和定量研究。文章在电镜水平上概括了木通科及其若干属的花粉特征,归纳了花粉外壁雕纹的基本类型,研究了花粉性状之间的内在联系,从花粉学角度进一步探讨了有关类群之间的亲缘关系,以及木通科花粉形态演化的一般趋势。Pollen morphology of 5 chinese genera, 20 species, 1 variety of Lar-dizabalaceae have been examined and quantitativly studied by using sca-nning electron microscope(SEM)and computer. On the basis of SEM. exa-mination, the paper describes the pollen morphology of Lardizabalaceaeand its chinese genera summarizes the essential scupturing types of pollenof Lardizabalaceae, studies the profound interrelationships among thepollen characters, the paper also discusses the systematic relationshipbetween ardizabalaceae, Sargentodoxaceae, and the relationships amongthe genera of Lardizabalaceae. Besides, the paper summarizes the generaltendency of pollen morphological evolution of Lardizabalaceae.
