氮沉降对植物-丛枝菌根共生体影响的研究进展

摘要

Nitrogen deposition is an important environmental factor affecting terrestrial ecosystems.Arbus-cular mycorrhizal fungi(AMF),as a kind of widespread soil microbes which symbiosis with most terrestrial plants significantly affected plant growth,nutrient uptake and resistance.However,the effect of nitrogen deposi-tion on plant-Arbuscular mycorrhizal symbiont was ignored.This paper summarized the effects of nitrogen dep-osition on the colonization characteristics,diversity of Arbuscular mycorrhizal ,and the effects of Arbuscular mycorrhizal on the growth and development,nitrogen metabolism,phosphorus uptake and biodiversity of host plant.And the research concerns were provided as well.%氮沉降是影响陆地生态系统的重要环境因子。丛枝菌根真菌(AMF)作为一种能够与绝大多数植物共生并广泛存在的土壤微生物，对植物生长、养分吸收以及抗逆性等均具有重要的调节作用，而针对氮沉降对植物-丛枝菌根共生体影响的研究往往被忽视。基于此，笔者从氮沉降对菌根侵染特性、菌根多样性、菌根对宿主植物生长发育、氮代谢、磷吸收以及对宿主植物生物多样性影响等方面进行了归纳总结，并提出应重点关注的研究方向，旨为菌根生理生态学的研究提供一定的科学依据。
