摘要: 对中国产独行菜属9种植物的花粉微形态作了扫描电镜下的观察和研究。结果表明,花粉粒为超长球形或长球形,具三沟,外壁纹饰均为网状纹饰。根据外壁纹饰可分为3种类型:(1)网眼为不规则形状,网眼边缘常有刺突;(2)网眼为圆形或近圆形,网眼边缘较光滑;(3)网眼为多边形或不规则多边形,网眼边缘较光滑,偶有刺突。

Abstract: The pollen morphology of 9 species of Lepidium(Brassicaceae)in China were observed and studied under the scanning electron microscope(SEM).It is indicated that pollen grains are perprolate or prolate,with tricolpate,reticulate sculpture;the exine sculpture may be divided into three types: the lumina irregular,the brink of the lumina not smooth,verrucate;the lumina circular or subcircular,the brink of the lumina smooth;the lumina polygonous or irregular polygonous,the brink of the lumina smooth,rarely verrucate.
