摘要
报道了山东大戟属 (EuphorbiaL .) 9种植物花粉的亚显微形态特征 .花粉粒的赤道面观呈近长球形 ,极面观呈三裂圆形 ;具三孔沟 ;表面纹饰均为网状 ;花粉粒极轴 2 7 3～ 5 6 3μm ,赤道轴 14 3～ 36 7μm .研究结果表明 。
The pollen submicroscopic morphology of nine species in the geuns Euphorbia L.from Shandong was reported. The pollen grains of the geuns are subprolate in equatorial view,3-labed-rounded and 3-colporate in polar view,and the exine sculpture is with ruticutate.The polar axis of the pollen grains is 27.7～56.3 μm,and the equatorial axis 14.3～36.7 μm.The results showed that the characteristic of pollen morpholopy of Euphorbia L.supports the traditional taxology for the geuns and species class.
