苗球兼用大白菜苗菜与球菜营养品质分析及评价

Nutritional Quality Analysis and Evaluation of Seedling and Heading Chinese Cabbage

以6个苗球兼用大白菜品种为试材,采收后比较了其营养品质及矿物质元素含量,以期为育种和生产实践提供参考。结果表明:苗菜干物质、维生素C、可溶性蛋白质及矿物质元素Ca、Fe、Mn、Zn都高于球菜;苗菜可溶性糖和矿物质Cu、Ca、Mn品种间变异程度较大,其它营养成分变异系数都比较小;球菜除干物质、Zn、Mn、P品种间变异程度较小外,其它营养成分品种间变异系数都比较大。同时,利用隶属函数法对6个品种的苗菜和球菜综合营养品质进行了初步评价,同一品种苗菜、球菜综合营养品质排序不一致,经分析,苗菜与球菜之间相关不显著。

Taking 6 varieties of seedling and beading Chinese cabbage as materials, the nutrition quality and mineral elements of them were tested to provide a reference for breeding and production. The results showed that the seedling of the dry matter content of food,VC content,soluble protein content and mineral elements Ca,Fe,Mn,Zn were higher than the heading; the seedling Chinese cabbage coefficients variation for soluble protein and mineral elements Cu, Ca, Mn were larger varieties than others. The coefficients variation of heading Chinese cabbage for the dry matter of food and Zn, Mn, P content were smaller in varieties variation;and other nutrients variation were larger between species. At the same time, using the method of subordinate function to the synthetical nutritional quality of six species had a preliminary evaluation, and it also showed that the list of quality of seedling Chinese cabbage was not accordance with that of heading Chinese cabbage,and they were not related.
