| 摘 要： | 通过对24个桉树品系遭受桉树枝瘿姬小蜂危害前后次生物质含量单宁和类黄酮含量动态变化研究，结果表明桉树品系遭受枝瘿姬小蜂危害后，叶片内类黄酮含量明显上升，高感品系类黄酮含量和增长变幅明显低于其他抗性类型的品系；而桉树叶片内单宁含量的动态变化规律表现为：高抗品系单宁含量明显高于高感品系，但随着进入小蜂危害期，其叶片内单宁含量出现一定程度下降，随后升高。次生物质的动态变化在不同抗性品系间差异显著，表明桉树叶片内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: | Studies were conducted on the change of secondary metabolite content of 24 Eucalyptus hazarded by Leptocybe invasa. The result showed that the flavonoids content increased significantly of 24 Eucalyptus clones after being damaged by Leptocybe invasa, and the flavonoids content of high sensitive clones is significant lower than other clones. The increasing amplitude of flavonoids content is remarkably/noticeably lower than that of clones after being damaged. The descending variation tendencies of tannins were high-resistant clones, middle-resistant clones and high- sensitive clones. The tannins declined when the clones was infected by Leptocybe invasa because it was used to defend the damaged ones. Therefore, the tannins in it continue to rise.The flavonoids content and tannins content has significant difference between 24 Eucalyptus clones. |
