竹篦舟蛾危害对毛竹次生物质及营养物质的影响

The Effect of the Damage Caused by Besaia goddrica (Schaus) on the Content of Main Secondary Substance and Nutrition Substance of Phyllostachys heterocycla cv. pubescens

通过研究毛竹受竹篦舟蛾危害后竹叶主要次生物质和营养物质的变化。结果表明:毛竹受竹篦舟蛾危害后,竹叶中单宁、黄酮的含量显著增加;总糖、可溶性糖、蛋白质、氮和磷的含量显著下降,下降量随着危害的加重而提高,竹叶中钾的含量则随着危害加重而上升。

The changes of main secondary substance and nutrition substance in the injured bamboo （Phyllostachys heterocycla cv. pubescens） leaves by the larvae of Besaia goddrica （Schaus） were explored in this paper. The results indicated that the contents of tannin and flavone significantly increased in the injured bamboo leaves. Contents of total sugar, soluble sugar, protein, N and P significantly decreased, and that of K increased in the injured bamboo leaves.
