东北延胡索及其数种近缘植物花粉形态研究

Studies on Pollen Morphology of Corydalis ambigua var. amurensis and Its Nearly Related Plants

用扫描电镜对东北延胡索极其近缘植物的花粉形态进行了观察 ,结果发现花粉粒在形状、大小、外壁纹饰、沟的长短及宽度等方面均有区别 ,从中获得了东北延胡索及其近缘植物分类方面的孢粉学依据 .

The pollen morphology of 5 species of Corydalis from northeast China was observed and compared by SEM.The results declared the shape and size of the pollen and exine sculpture of the 5 species were basically stable and could serve as a taxonomic character.
