不同大白菜品种主要营养分布特点分析

Comparative Analysis of Main Nutrient Distribution Characteristics of Different Chinese Cabbage Varieties

以不同大白菜品种为试验材料,对莲座叶、叶球外叶、叶球内叶及其各部分叶片的软叶和叶柄中的可溶性糖、可溶性蛋白质、维生素C进行测定及相关分析。结果表明,不同品种不同部位营养含量不同,差异较明显;参试品种以亚细亚、胶研秋强、秦白2号综合营养含量较高,陕秋白较低。总体而言,参试品种软叶维生素C和可溶性蛋白质含量高于相同部位叶柄含量;大部分参试品种叶柄可溶性糖含量高于相同部位软叶含量。参试品种V;含量在软叶和叶柄不同部位的分布特点不明显,可溶性糖含量在软叶和叶柄中分布由外到内大体上呈递增趋势;不同品种软叶可溶性蛋白质含量在叶球内叶和外叶分布存在差异。

Different varieties of Chinese cabbage were used as experimental materials,the soluble sugar,soluble protein and vitamin C in lotus leaf,outer leaf of leaf bulb,inner leaf of leaf bulb,soft leaf and petiole of leaf parts were determined and relative analysis was made.The results showed that different varieties and different parts of the nutrient content was different,the difference was obvious.Among the tested varieties,Asiya,Jiaoyanqiuqiang and Qinbai 2 had higher comprehensive nutrient content,Shaanqiubai lowest.In general,the contents of vitamin C and soluble protein in soft leaves were higher than those in petioles of the same part.The content of soluble sugar in petiole of most tested varieties was higher than that in soft leaves of the same part.The distribution characteristics of V;content in different parts of soft leaf and petiole were not obvious,the content of soluble sugar in soft leaves and petioles increased from outside to inside,there were differences in the distribution of soluble protein content in the inner and outer leaves of soft leaves of different varieties.
