摘要:

利用扫描电子显微镜,对葫芦科8属10种1变种植物的花粉形态进行观察研究。结果显示:冬瓜属、葫芦属和栝楼属的花粉粒为近球形,具3孔沟; 苦瓜属、西瓜属和丝瓜属的花粉粒为长球形,具3沟; 黄瓜属的花粉粒为近球形,具3孔; 南瓜属的花粉粒为球形,具散孔。花粉粒大小、形状和外壁雕纹属、种间差异显著。

Abstract:

The pollen morphologies of ten species and avariety belonging to eight genera of Cucurbitaceae in were examined by scanning electron microscope. The results showed that the pollen grains of Benincasa,Lagenaria and Trichosanthes are approximate spheroid with three-colposate; the pollen grains of Momordica,Citrullus and Luffa are prolate spheroid with three-colpus; the pollen grains of Cucumis is approximate spheroid with three-porus; the pollen grains of Cucurbita is spheroid with panpori. There are extinct differences in size,shape and exine sculpture of the pollen grains between different genera and species.

Key words: Cucurbitaceae pollen morphology scanning electron microscope
