摘要/Abstract

摘要： 以中亚热带常绿阔叶林外生菌根树种罗浮栲和丛枝菌根树种木荷为研究对象,采用根袋法进行野外原位氮添加试验,研究了细根形态性状(比根长、比表面积、组织密度、平均根直径)和构型性状(分枝数、分枝比、根长增长速率、根尖密度、分枝密度),分析不同菌根树种细根形态和构型性状对氮沉降的响应。结果表明: 随序级增加,外生和丛枝菌根树种细根比根长、比表面积和分枝数对氮添加的塑性响应逐渐降低,组织密度则相反;这反映了不同分枝等级细根的养分获取与资源维持在序级间存在权衡关系。不同菌根树种对土壤氮有效性的变化采取不同的适应对策: 氮添加后,罗浮栲细根采取机会主义策略,依靠细根本身来提高养分吸收效率、增强空间扩展和就地养分吸收能力,以快速的养分吸收策略为主;而木荷通过养分吸收效率和根系构建成本之间的权衡,并未改变细根形态性状,更多地依赖于菌根菌和细根构型之间的互补性进行养分获取。外生和丛枝菌根树种维持和构建细根碳(C)成本的差异,导致细根采取最适合自身的养分捕获方式,以达到生存的最优策略。

关键词: 氮添加, 菌根类型, 细根形态和构型性状, 可塑性响应, 养分获取策略

Abstract: We measured the morphology traits (specific root length, specific root surface area, root tissue density, average root diameter) and architecture traits (root fork, root fork ratio, increase rate of root length, root tip density, root fork density) of fine roots in two mycorrhiza tree species, Castanopsis faberi (ectomycorrhizal) and Schima superba (arbuscular mycorrhizal), in an evergreen broadleaved forest in the middle subtropical zone. Root bags method was used in an in situ nitrogen deposition experiment. The aim of this study was to reveal the differences in the plastic responses of fine root morphology and architecture traits to nitrogen deposition between the different mycorrhizal trees. The plastic responses of specific root length, specific root surface area and root fork to nitrogen addition decreased from the first-order root to the fourth-order root, while root tissue density showed an opposite pattern. Such a result indicated a trade-off between nutrient acquisition and resource maintenance of different fine root orders. Different mycorrhizal tree species adopted diffe-rent adaptation strategies to the variations of soil nitrogen availability. C. faberi adopted an opportuni-stic strategy, which relied on fine root to improve nutrient absorption efficiency, enhanced the capacity of space expansion and in-situ nutrient absorption to focus on rapid nutrient absorption strategy. S. superba did not change fine root morphological traits through the trade-off between nutrient absorption efficiency and root construction cost, but relied more on the complementarity between mycorrhizal fungi and fine root architecture traits for nutrient acquisition. The differences in the cost of maintaining and constructing fine root C between different mycorrhizal trees led to fine root adopting the most suitable nutrient capture strategy.

Key words: nitrogen addition, mycorrhizal type, fine root morphology and architecture trait, plastic response, nutrient acquisition strategy
