摘要:  为探讨遭受桉树枝瘿姬小蜂(Leptocybe invasa Fisher & La Salle)危害后桉树(Eucalyptus sp.)的次生代谢产物的变化,对24个桉树品系受危害前后的次生物质单宁和类黄酮含量的变化进行了研究。结果表明,桉树品系遭受枝瘿姬小蜂危害后,叶片内的类黄酮含量明显上升,高感品系的类黄酮含量明显低于其他抗性类型的品系。受虫害前高抗品系桉树叶片中的单宁含量明显高于高感品系,但进入小蜂危害期,叶片单宁含量出现先下降后升高的趋势。次生物质的动态变化在不同抗性品系间差异显著,表明桉树叶片的单宁和类黄酮含量与抗枝瘿姬小蜂有显著关系,可作为检测桉树对枝瘿姬小蜂抗性的指标。

Abstract:  In order to understand the changes in secondary metabolite of Eucalyptus demaged by Leptocybe invasa, the contents of flavonoid and tannin in 24 strains of Eucalyptus invasived by L. invasa were studied. The results showed that flavonoid content in Eucalyptus leaves increased significantly after damaged by L. invasa, and the flavonoid content in high sensitive strains was significantly lower than that in other strains. The tannin content in high-resistant strains was significantly higher than that in high-sensitive strains before damaged by L. invasa. The tannin content in high-resistant strains declined at first, and then increased after infected by L. invasa. Therefore, tannin and flavonoid contents in Eucalyptus leaves could be used as indexes to detect whether Eucalyptus damaged by Leptocybe invasa or not.
