摘要
目的:对不同产地的菘蓝种质资源进行植物性状比较与质量评价研究,以期为菘蓝优良品种选育工作奠定基础。方法:采用大田栽培,随机区组法,对不同产地引进的菘蓝叶、根、角果、种子等器官的植物性状进行比较,并测定其根中有效成分R,S-告依春和多糖的含量。结果:不同栽培类型菘蓝在叶、根、角果、种子形态方面存在显著差异,根中R,S-告依春和多糖含量也存在差异,其中白菜叶型菘蓝(云南)的R,S-告依春含量较高,质量分数为0.59%,四倍体的多糖含量较高,质量分数为8.68%。结论:根据菘蓝的植物性状可将其分为白菜叶型、甘蓝叶型、芥菜叶型,白菜叶型菘蓝(云南)的R,S-告依春含量较高,四倍体的多糖含量较高。
Objective： To lay a foundation for the study on good variety selection of Isatis indigotica, comparison of plant traits and quality evaluation of Isatis germplasm resources from different production area was conducted. Method ： Field cultivation and randomized block experiment were adopted to compare those plant traits of leaf, root, silique and seed of Isatis from different production area and the content of R,S-goitrin and polysaccharide in the root was determined. Result： Different cultivation forms of Isatis had significant difference from each other in leaf, root, silique and seed, content of R, S-goitrin and polysaceharide in the root were also different. R,S-goitrin content in Isatis of Chinese cabbage leaf type （ production area： Yunnan ） was comparative higher, 0.59% , while polysaccharide content in autotetraploid Isatis was comparative higher, 8.68%. Conclusion： According to the plant traits, lsatis were classified into three types： Chinese cabbage leaf type, cabbage leaf type and mustard leaf type, of which R,S-goitrin content in Chinese cabbage leaf type （production area： Yunnan） was comparative higher, while polysaccharide content in autotetraploid Isatis was comparative higher.
