摘要
板蓝根是防治病毒性感冒的核心药材,目前我国栽培的板蓝根种质较多,归纳有大叶板蓝根、小叶板蓝根和四倍体板蓝根三大类型,针对这三种形态特征明显不同的板蓝根种质,进行了生物学特征、种子形态特征、农艺性状以及药用成分含量等的比较研究,通过比较发现,小叶板蓝根优于四倍体板蓝根,而四倍体板蓝根优于大叶板蓝根。
Radix isatidis is the important Chinese medicinal materials for anti-virus. In this paper the different germplasm resources of Radix isatidis in China, which are big-leaf and little-leaf varieties with diplidy and the tetraploidy ,are evaluated. We compared the biological characters, seed shape, agricultural characters, molecular evolution and chemical constituents of the three germplasm resources. From these comparings, we concluded that the little-leaf Radix isatidis is better than the tetraploidy Radix isaticlis, and the tetraploidy is better than the big-leaf Radix isatidi.
