研究表明,毛竹受毛竹黑叶蜂危害后,竹叶中单宁含量随着危害的加重显著增加,干物质单宁的含量由未受害时0.386 mg/g 增加到重度受害时的0.553 mg/g;总酚含量随着受害程度的加重呈显著下降趋势,由未受害时3.763 mg/g 下降到中度受害时的3.126 mg/g,再下降到重度受害时的2.653 mg/g;竹叶中黄酮的含量呈上升趋势,由未受害时2.631 mg/g 增加到重度受害时的3.658 mg/g.试验得出:毛竹受毛竹黑叶蜂危害后竹叶中单宁、总酚、黄酮含量变化均属于毛竹受害后的生理应激反应.

@@@@This study shows that the content of tannin in leaves of Phyllostachys heterocycla cv. Pubescens increase after the damage caused by Eutomostethus nigritus. The content of tannin is 0.386 mg/g in undamaged leaves whereas that of the severe damaged leaves is 0.553 mg/g? The content of phenols in leaves decrease after the damage caused by Eutomostethus nigritus. The content of phenols is 3.763 mg/g in undamaged leaves whereas that of moderate harmed leaves is 3.126 mg/g, and that of severe harmed leaves is 2.653 mg/g? The content of flavonoids in leaves increase after the damage caused by Eutomostethus nigritus. The content of flavonoids is 2.631 mg/gin damaged leaves whereas that of moderate harmed leaves is 3.658 mg/g.
