摘 要:测定9个不同施肥处理下元宝槭叶内黄酮类化合物、绿原酸和N、P、K、Ca、Mg、Fe、Zn、Cu、Mn和B的含量与积累量,通过主成分分析影响黄酮类化合物、绿原酸含量的因子。研究结果表明:N0P250K75和N0P125K37.5处理下元宝槭的黄酮类化合物、绿原酸积累量比对照增加1~1.5倍,是叶用原料林的最佳施肥配方;施肥处理下营养元素的含量与积累量呈正相关,但黄酮类化合物、绿原酸含量与积累量并不呈正相关;"光合与氮素代谢促进"因子和"酶促反应促进"因子是影响黄酮类化合物和绿原酸含量的两个最主要的成分,其变异积累贡献率在87%以上,且以P、Cu、Mg的负荷量最大,可通过调节叶内营养元素的含量对黄酮类化合物和绿原酸的含量进行调控。By determining the content of flavonoid ,cholorogenic acid and ten nutrition elements in the leaves of Acer truncatum treated by 9 kinds of nutrition supplying, by analyzing the principal components, the dynamic relationship among nutrition elements and the content of flavonoid and cholorogenic acid were investigated. The result indicated that the content of flavonoid and cholorogenic acid in leaves of the two best fertilization treatments was 100%NFA48150% higher than the control. The effect of treatment on the content and the accumulation content of nutrition elements was similar, but the effects on flavonoid and cholorogenic acid was negatively correlated. Of the five principal factors affecting the content of flavonoid and cholorogenic acid, two were found to be principal: factors of promoting photosynthesis and nitrogen, and factors of promoting enzyme react. The accumulated variation cortribution rate of the two factors was more than 87% and the loading of P, Cu and Mg was the biggest among the loading matrix of principal components.
