Selection and deployment of browsing resistant Eucalyptus globulus and Eucalyptus nitens.

有袋类动物的啃食是澳大利亚桉树种植园的一个重要问题。迄今为止，浏览控制一直依赖于使用1080种农药，但在政治和社会压力下，这种做法将于2005年12月在塔斯马尼亚州立森林停止。为了开发害虫综合治理的新方法，我们将探索利用天然植物对有袋动物浏览者的抗性。本研究将确定蓝桉（Eucalyptus globulus）和绿桉（E. nitens）幼苗抗性的遗传和化学基础，并通过树木发育和不同地点考察其抗性的稳定性。抗性种质将在操作种植中进行鉴定和试验。

Marsupial browsing is a significant problem for eucalypt plantation establishment in Australia. To date, browsing control has relied on the use of 1080 pesticide, but through political and social pressure this will cease in Tasmanian State Forests by December 2005. To develop new approaches to integrated pest management, we will explore the use of natural plant resistance to marsupial browsers. We will determine the genetic and chemical basis of seedling resistance in Eucalyptus globulus and E. nitens, and investigate the stability of resistance though tree development and across different sites. Resistant germplasm will be identified and tested in operational plantings.
