| 摘 要： | 本文利用扫描电子显微镜和光学显微镜研究了丁香属代表植物11种和2个变种的花粉形态,并对花粉的表面纹饰等性状用电子计算机进行了主分量分析,同时将计算结果作了二维与三维排序,结果表明:(1)丁香属植物花粉形态在光学显微镜下种间区别甚微,而在电镜下的区别则明显,可做为分种的依据,尤其对形态上难以区分的种类更为适用;(2)根据花粉外壁表面纹饰等特征,将所做花粉分为四种类型;(3)除欧丁香外,其余花粉均为三孔沟型,对前人的工作作了一定的修正;(4)通过主分量分析,指出了花粉孔的宽/长,沟长及网眼大小是本属花粉分类的主要成分;(5)试图通过主分量的二维和三维排序,为属下分组,分种提供新的观点和依据。

| Abstract: | Abstract The pollen grains of 11 species and 2variety belonging genus Syringa from China were examined under light microscope and scanning dlectron microscope. Depending on morphological charectristics, the pollen grains of Syringa could be divided in to four types. All of them are 3 -colporate except S. vulgaris which are 3-colpate. In addition, the exine ornamentations of pollenwere treated as Principal Components analysis by computer and the results was analysised with Two-dimensional ordination and Three - dimensional ordination. It seems that the wide/ lenghth of aperture, the lenghth of colpus and the size of reticulate be the principal elements in pollen grains classification. Key words Syringa; Pollenmorphology; computer; principal components amalysis. |
