摘要: 用扫描电镜方法观察木兰属(Magnolia)几种药用植物的花粉粒及花药,其共同形态特征是:花粉粒近球形或长球形,具单沟或不具沟;外壁光滑或较粗糙。花药表皮细胞纺锤形或柱形,排列紧密,具条状纹饰。Abstract: The pollen grain and anther of five species of the genus Magnolia were observed by scaning electron microscopy.The general morphological features were as follows:The shape of the pollen grain are ball or ellipsoid possessing monocolpate or not;The surface are smooth and fine or rough;The anther's epidermal cell are spindle or columnar, arrange close together,and sculpture are striate.
