摘要
本文运用扫描电镜对内蒙古地区常见农田杂草（１０科２２种）种皮的微形态特征进行了观察，着重了解各科植物种皮表面纹饰的特征，比较不同科、属、种间的差异。结果表明，种皮表面纹饰具有丰富的多样性，系非保守性状，科间差异显著，在属以下类群的分类学研究中尚有较高的价值。研究结果不仅为植物检疫、种子鉴定，还为植物分类提供了有用的资料。
The micro-morphology of weeds (10 families, 22 species) seed testa, especially surface ripples ,was observed by the scanning electron microscope so as to compare the differences in different families , genera and species .The result indicated that testa ripples are of the diversity and differences between families. The result of this research offered important reference in plant sanatation ,seed certification and plant taxonomy.
