| 摘 要： | 本文对内蒙古地区常见的农田杂草（８科１６种）种子的形态进行了观察，特别运用扫描电镜对其种皮的微形态特征进行了比较分析，着重了解各科植物种皮表面纹饰的特征。结果表明，种皮表面纹饰性状稳定，且具有丰富的多样性，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。研究结果为植物检疫，种子鉴定及植物分类提供了有用的资料。 |
| 关 键 词： | 农田杂草；种皮纹饰；微形态 |

| Abstract: | Seed characteristics,especially the sculpturing on the surface of seed coats of 6 weeds belonging to 8 families from Inner Mongolia were studied.Comparisons were made between different species in the micromorphological characters of the seed coats by using Scanning Electronic Microscope.The results indecated that sculpturing on the seed coat surface was a stable trait,although it showed a wide range of diversity among different species.This character could be used as a valuable index in taxonomic study and in seed identification practice. |
| Keywords: | agricrltural weeds seedcoat sculpturing micromorphology |
