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 study the comparisons and quality evaluation of plant traits of Camellia insignis in different habitats, with a view to laying the foundation for Breeding Blueberry varieties. Methods: Field traits and randomized block method were used to compare the plant traits of the leaves, roots, horns, seeds and other organs introduced from different habitats, and the effective components R, S- Content. Results: There were significant differences in the morphological characters of leaves, roots, pods and seeds between different cultivars. There were also differences in the contents of R and S-ascorbic acid and polysaccharides in roots. Among them, the contents of R, The content of polysaccharides in tetraploid was higher with the content of 8.68%. CONCLUSION: According to the plant traits of Isatis indigotica, it can be divided into R, S-report and Cotyledonary activity of tetraploid polysaccharides by cabbage leaf type, cabbage leaf type, mustard leaf type and cabbage leaf type barberry blue (Yunnan) High content.
