猕猴桃属9种植物的花粉形态研究

STUDIES ON THE POLLEN MORPHOLOGY OF NINE SPECIES OF GENUS ACTINIDIA

  • 摘要: 本文利用扫描电镜和光学显微镜研究了猕猴桃属6种和3变种植物的花粉形态。本属花粉粒具三孔沟或三拟孔沟,外壁纹饰差异较大。可作为该属属下分组的重要依据之一。根据外壁纹饰,可将它们概括为4种类型:(1)皱块状表面具细条纹;(2)不规则的瘤状纹饰;(3)小沟状或小穿孔状;(4)较规则的瘤状纹饰类型。

     

    Abstract: The pollen grains of 5 species and 4 varieties belonging to the genus Actinidia have been examined by light microscope (LM) and scanning electron microscope (SEM). They are shapes of prolate, subprolate, spheroidal and oblate, size ranging from 17.62×14.96μm to 28.10×20.53μm, and have aperture of tricolporate or tricolporoidate; And exine ornamentation has four types, namely, rugulae with fine striae, irregularly tuberculate, fossulate or perforate and regularly tuberculate. The characters of the pollen grains in Actinidia mentioned above can be allow to be evidences for the identification of individual species and varieties. An evolution character of pollen morphology is discussed in the paper.
