亚热带酸雨区马尾松EM根尖真菌群落多样性分析
Fungal community on ectomycorrhizal root tips of Pinus massoniana in subtropical acid rain area
[目的]揭示亚热带酸雨区不同林型中马尾松外生菌根(EM)根尖的真菌群落多样性、结构和组成的差异,探讨EM根尖真菌群落缓解土壤酸化的机制。[方法]以重庆铁山坪林场的马尾松纯林(Pi)、马尾松-香樟混交林(Pi_Ci)以及马尾松-木荷混交林(Pi_Sc)为研究对象,采用样地调查和分子生物学相结合的方法,对不同林型中马尾松EM根尖的真菌群落进行研究。[结果](1)三种林型的马尾松EM根尖样品中共获得 3737 个真菌OTUs,隶属于 15 门 60 纲…查看全部>>
[Objective]In order to reveal the differences in diversity,structure and composition of ectomycorrhiza(EM)root-tip fungal communities of Pinus massoniana in different forest types in subtropical acid rain area,and to explore the mechanism of EM root-tip fungal communities alleviating soil acidification.[Method]P.massoniana EM root-tips were collected from pure P.massoniana stands(Pi),mixed plantations with Cinnamomum camphora(Pi_Ci)or Schima superba forest(P…查看全部>>
