| 摘 要： | 应用电镜扫描技术对狗尾草属两个种花粉粒的形态、表面细微结构、萌发孔、孔盖以及花药内壁进行了观察.结果表明花粉粒呈圆形或近似圆形,具有一个萌发孔和孔盖,花粉粒表面有粗糙突起或星状颗粒.这些性状在栽培种和野生种之间存在差异.谷子花药内壁的星状体可作为雄性不育鉴定的一项重要形态指标.

| Abstract: | The morphologic characters of pollen grain in two species ot Setaria have been observed by use of electron microscope. The result shows that the shape of pollen grains are round or approximately round. The surfaces of the pollen grain are rather rough, full of projection or starlike grains.Each pollen has an aperture and a lid on it. The characters which mentioned above are different between cultivated varieties and wild spcies. Therefore the aster grain on the inner wall of the pollen may be an important morphological index for identification of male sterillity. |
