项目摘要
Preliminary results from the ongoing work of a multidisciplinary study that aims at a scientific basis for a sustainable management of the Munessa-Shashemene forest as a model for other semi-decidouous forests of Ethiopia, reported the so-called nurse-tree effect. They documented higher density of regenerating native species under canopies of introduced Eucalyptus saligna, and E. globulus as compared to regeneration density in a natural forest. In such forest ecosystems, where seeds are dispersed without their mycorrhizal symbiont, tree species acquire a symbiont at the time of germination and the effectiveness of the existing AMF community is one important component of seedling establishment and growth. To get a better knowledge of the functioning of this particular ecosystem the work shall be complimented by investigation of the mycorrhizal status and the diversity of arbuscular mycorrhizal fungal (AMF) communities colonizing the nurse trees and the regeneratin indigenous tree seedlings. The project will also evaluate the mycorrhizal state of seedlings of diverse indigenous trees studied in respect to nutrient situations and water availability. Finally the project will provide inoculum of indigenous AMF for experimental designs and nurseries.
正在进行的一项多学科研究的初步结果报告了所谓的苗圃效应,这项研究的目的是为可持续管理Munessa-Shashemene森林提供科学依据,作为埃塞俄比亚其他半落叶林的模式。他们记录了引进的柳桉和E.与天然林的更新密度相比。在这样的森林生态系统中,种子是分散的,没有它们的菌根共生体,树种获得一个共生体在发芽的时候,现有AMF社区的有效性是幼苗建立和生长的一个重要组成部分。为了更好地了解这一特殊生态系统的功能,这项工作应通过调查菌根状况和丛枝菌根真菌(AMF)群落的多样性来补充。该项目还将评估各种土著树木幼苗的菌根状况,研究其营养状况和水的供应情况。最后,该项目将为实验设计和苗圃提供本地AMF接种物。
