摘要:
综述了国内外关于外生菌根提高树木抗旱性机理研究的现状与进展,认为外生菌根主要通过形态特征的变化,生理生态特性的改变,以及酶活性的提高来增强林木在干旱胁迫环境中的生存能力;并提出在积极建立干旱、半干旱地区外生菌根真菌资源库,开发优良乡土菌株的基础上,尝试引入适应性强的优良外来菌根真菌,或采取基因重组等分子生物学技术培育抗旱性菌株的思想,这将为菌根技术在西部极度干旱及退化的生态系统中植被恢复提供新思路.
Abstract:
The mechanism of ectomycorrhizae to drought resistance was extensively discussed.Its main mechanism involves morphological,physiological,and ecological adaptations,and the enhanced efficiency of the associated enzymes.The authors also discussed the introduction of highly adaptive foreign ectomycorrhizal fungi,in addition to the establishment of the resource bank of indigenous ectomycorrhizal strains,as a promising alternative to developing ectomycorrhizal fungi for semi-arid and arid regions.The role of molecular biotechnology such as gene engineering was also discussed.These discussions may provide a new concept in applying the technology of ectomycorrhizae in extremely arid regions in western China.
