摘要
为筛选出性状优异的板蓝根种质,对不同地区引入的6份板蓝根种质资源进行形态学、农艺学性状等方面的比较研究。结果表明:这6份种质资源中,I5为四倍体板蓝根,叶面积最大,叶片数量最多,但在本地区的出苗率较低。其余5种为小叶板蓝根,在小叶板蓝根中,植株根长最长的为I1,长度可达25.7cm。单株叶数最多、大青叶产量较高的种质资源为I2,干产为2960kg·hm^-2。板蓝根产量相对较高的种质资源为I4和I6,干产分别为1887和1808kg·hm^-2。侧根数最少的种质为I3,平均单株为4.2条。
In order to screen excellent germplasm of Isatis indigotica,in this study,the morphological and agronomic characteristics of six different germplasm resources of Isatis Indigotica were compared.The results showed that among the six germplasm resources,I5 was the tetraploid Isatis indigotica.It had the largest leaf area and the largest number of leaves.The other 5 species were Isatis microphylla.Among the other 5 species,I1 has the longest root and the length was 25.7 cm.The germplasm resource with the largest number of leaves and high yield of Isatis indigotica was I2.The dry yield was 2960 kg·hm^-2.The germplasm resources with high yield root were I4 and I6.The dry yield were 1887 and 1808 kg·hm^-2.The germplasm with the least number of branch root was I3.The average was 4.2 per plant.
