| Abstract: | The procedures of microsporogenesis and male gametophyte formation of Clematis hexapetala were observed by traditional paraffin section technique.The results indicated that the cross-section of anther was butterfly-shaped,each anther included four pollen sacs;microspore were tetrahedron-shaped;mature pollens were subglobose,two-cell type,with three germinal furrows;wall of pollen sac was consisted by four layers,i.e.epidermis,endothecium,middle layer and tapetum;tapeta were secretor type. |
