不同种源香椿嫩芽营养成分差异分析

Difference analysis of nutritional components in tender buds of Toona sinensis from different provenances

  • 摘要: 为探究不同种源香椿嫩芽的产量和营养成分的差异,初步筛选出适宜贵州贵阳的菜用香椿种源。选取贵州8个种源1年生苗的嫩芽为试材,测定嫩芽的产量和营养成分指标,对各性状进行方差分析和主成分分析,结果表明:不同种源香椿嫩芽产量变幅为64.02—150.48 g。各指标的变异系数范围变幅5.30%—41.35%,Fe元素含量的变异系数最大,主成分分析显示前5个主成分累计贡献率为92.641%。综合分析得出长顺、安龙和贞丰的种源可作为贵州贵阳菜用香椿培育优先考虑的种源。

     

    Abstract: In order to explore the differences in yield and nutritional components of T. sinensis buds from different provenances, the vegetable T. sinensis provenances suitable for Guiyang, Guizhou were preliminarily screened. The buds of one-year-old seedlings of eight provenances in Guizhou were selected as test materials, and the yield and nutrient composition indexes of buds were determined. The variance analysis and principal component analysis were carried out on each trait. The results showed that the yield of buds of T. sinensis from different provenances ranged from 64.02 g to 150.48 g. The coefficient of variation of each index ranged from 5.30 % to 41.35 %, and the coefficient of variation of Fe element content was the largest. The principal component analysis showed that the cumulative contribution rate of the first five principal components was 92.641 %. Comprehensive analysis showed that the provenances of Changshun, Anlong and Zhenfeng could be used as the priority provenances for the cultivation of vegetable T. sinensis in Guiyang, Guizhou.
