【摘要】 对东北地区产毛莨科乌头属（ＡｃｏｎｉｔｕｍＬ．）１６种植物的花粉材料进行了扫描电镜观察。结果表明：花粉具３个萌发孔；沟膜明显，具瘤或颗粒；沟间具小刺状纹饰或近于光滑，偶见穿孔网状；极面观三裂圆形或钝三角形；赤道面观为圆形、近矩形、宽椭圆形至长椭圆形。结合其它诸学科的研究成果，讨论了花粉形态的演化及其在分类学上的意义，为该属的系统分类提供依据。更多还原

【Abstract】 Pollen morphological of 15 species in Aconitum L. in the northeasten China was inuestigated with Scanning Electron Microcopies(SEM). There are three colpi of which membrane on which there are Tuberculates and Granulates is very obvions on pollen. Between colpi, the ornamentation is Spinulate or smilar smooth. Polar view of pollen is blunt 3 angular or 3 lobedcricular, and equalorial view is from cricular, wideellipic to narrowellipic, few reticulate. Combining this results with the ones of ather sciences, the evolution of pollen morphology and its taxonomic significance are discussed and provide scientific basis for the systematic in the genus.更多还原
