| 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. |
