为研究油桐尺蠖危害对桉树内含物的影响,对未受害、轻度受害、中度受害、重度受害4种受害程度的桉树叶片的黄酮、单宁、可溶性糖、和蛋白质等4种内含物含量进行了测定和比较。结果表明：桉树受到油桐尺蠖危害后,通过调节体内含物的种类及含量,主动地、积极地产生一系列生理生化反应,阻止害虫进一步为害。其中受害后桉树叶片黄酮和单宁等次生代谢物质的含量显著上升,可溶性糖、蛋白质营养物质含量则呈显著下降,表现出明显的应激防御反应。
為研究油桐呎蠖危害對桉樹內含物的影響,對未受害、輕度受害、中度受害、重度受害4種受害程度的桉樹葉片的黃酮、單寧、可溶性糖、和蛋白質等4種內含物含量進行瞭測定和比較。結果錶明：桉樹受到油桐呎蠖危害後,通過調節體內含物的種類及含量,主動地、積極地產生一繫列生理生化反應,阻止害蟲進一步為害。其中受害後桉樹葉片黃酮和單寧等次生代謝物質的含量顯著上升,可溶性糖、蛋白質營養物質含量則呈顯著下降,錶現齣明顯的應激防禦反應。

To study flavone, tannin, soluble sults showed that： been the effects of inclusions in Eucalyptus damaged by Buzura suppressaria, the contents of sugar and protein in different damage degrees were measured and compared. The redamaged by Buzura suppressaria, the Eucalyptus regulated the types and contents of inlusions and produced a series of physiological and biochemical reactions to prevent further damaged by the pests. Such as significantly increased the contents of falconoid and tannin and significantly decreased the contents of soluble sugar and protein in leaves. The Eucalyptus showed significant stress reaction against the pests.
