杉木(Cunninghamia lanceolata)吸收根和丛枝菌根对不同环境因子的响应
Responses of absorptive root and mycorrhizal colonization of Chinese fir(Cunninghamia lanceolata)to varied environmental conditions
[目的]为了解树木细根分枝与从枝菌根共生之间的关系,以及它们对环境条件的响应。[方法]本研究以分布在中国亚热带不同环境条件下的 11 个杉木人工林为研究对象,研究与杉木 1 级根资源获取策略有关的性状(1 级根/2 级根分枝比、丛枝菌根(AM)侵染率)与环境因子包括年平均降水量(MAP)、年均温(MAT)、土壤C、土壤N、土壤P、土壤pH的关系。[结果]1 级根/2 级根分枝比对环境条件更为敏感。1 级根/2 级根分枝比与MAT呈正相关,但与土壤…查看全部>>
