摘要：对盐肤木叶片成分分析结果表明 :寄生角倍的叶片与正常叶片相比 ,叶组织内的氨基酸和Vc的浓度由 11.0 6 % ,1.15 %降低到 7.85 %和 0 .6 8% ,幅度很大 ;总N和单宁的浓度也略有降低 ,而可溶性总糖的浓度则稍有升高。通过盆栽施肥试验得出 :N、P肥不但可促进盐肤木幼树生长 ,并影响叶片内Vc的含量 ,但对叶片内的可溶性糖、单宁及总氮含量没有明显的影响 ;施N肥对叶组织的碳氮比(C/N)
The concentrations of some contents in the leaves of Rhus chinensis were studied in this paper. The results indicated that the concentration of vitamin C and total amino acids in normal leaves without gall were 1.15% and 11.1%. But it reduced rapidly to 0.68% and 7.85% in leaves with horned galls hosted. The concentration of soluble sugar and tannin acid also changed between the leaves with and without galls hosted. A hypothesis based on this evidence is proposed that the development of gall tissue and metabolizing of gall aphids depleted huge amount of the two kind of substance and lowered their contents in the leaves of host tree. The fertilization effect of young tree is carried out by pot experiment: the growth of height, caliper, fresh weight and the size of leaves were affected by add different quantities of nitrogenous or phosphate fertilizer, the concentration of vitamin C was more susceptible to fertilizer than that of tannin and soluble sugar.
