竹织叶野螟危害对毛竹叶片次生物质含量的影响

Influence of Algedonia coclesalis Damage on the Secondary Metabolite Content of Phyllostachys heterocycla Leaves

研究了毛竹受竹织叶野螟危害后,竹叶次生物质含量的变化。结果表明,毛竹受竹织叶野螟危害后,竹叶中单宁和黄酮含量增加,总酚含量下降。说明毛竹次生代谢物质和抗虫性之间有密切的关系。

Researches were conducted on influence of Algedonia coclesalis damage on the secondary me- tabolite content Phyllostachys heterocycla leaves. The results showed that the content of tannins and fla- vonoids increased , and the total phenol content decreased in leaves of Phyllostachys heterocycla. There was a close relationship between secondary metabolites and insect resistance.
