摘要：

基于功能性状的研究方法广泛地应用于生态学研究, 用于解释不同层次的复杂的生态学过程, 而绿色植物叶片的功能性状长期被认为对植物的生存、生长和繁殖具有重要的影响。该研究对玛曲高寒沼泽化草甸51个植物种(分属于14科)的叶片形态和光合性状进行测量, 比较不同物种和不同功能群(莎草科、禾本科和双子叶类杂草)的差异, 分析叶片形态特征和叶片光合性状之间的相关性。结果表明: 1)不同物种、不同功能群之间在比叶面积、净光合速率和水分利用效率等叶片形态和光合特征方面有着显著的差异, 例如禾本科植物具有较高的比叶面积和水分利用效率, 双子叶类杂草具有较大的叶面积, 而莎草科植物具有较高的净光合速率。2)相关性分析结果显示, 无论在物种水平还是功能群水平, 叶片形态和叶片光合性状之间都具有显著的相关关系。该研究揭示了高寒沼泽化草甸植物物种在叶片功能性状上的显著分化, 进而使得这些物种能在同一个草地群落中共存, 而群落中不同功能群物种的组成差异将会对群落的结构、功能和资源利用产生显著的影响。该研究将为进一步研究高寒沼泽化草甸提供基础研究数据并为其保护和恢复提供生理生态学依据。

Abstract: Aims

Trait-based approaches are often widely used in ecological research to predict or explain the complex ecological processes at both individual and ecosystem levels. Leaf function with morphological and physiological traits can play important roles in plan growth, survival, reproduction in natural environments. The aim of this study is 1) to determine the differences of leaf traits between both the species and the functional groups in a swamp meadow; 2) to explore the relationship between different leaf morphological traits and physiological traits.

Methods

Gas exchanges of 51 species (in 14 families) were measured on six fully expand health leaves (from different individual plants) using a portable photosynthesis system in the field during the peak of growing season. The leaf morphological traits was measured based on 6 single leaves form different individuals, include the net photosynthesis rate (P_n), transpiration rate (T_r), specific leaf area (SLA), relative leaf water content (LWC), leaf area (LA) and the water use efficiency (WUE = P_n/T_r).

Important findings

Result showed that there were significant interspecific differences in the investigated traits as described in above methods. Among the traits, the LWC (coefficient of variation, CV = 0.11) was ranged from 58.12% to 81.83%, 0.0088-0.0278 m²·g^-1 for the SLA (CV = 0.27), and 0.51 cm² to 100.90 cm² for the LA (CV = 1.73), while the range of 4.25-19.23 μmol CO₂·m^-2·s^-1, 2.89-12.81 mmol H₂O·m^-2·s^-1 and 0.56-3.76 μmol CO₂·mmol^-1H₂O for P_n (CV = 0.33), T_r (CV = 0.33), and WUE (CV = 0.36), respectively. There were also significant differences between the functional groups (sedge, grass and forbs) for these traits. Forbs have larger LA and higher LWC than sedge and grass; Grass have higher WUE and SLA than those of others; while Sedge have higher P_n. Our result also showed there were high correlation between P_n and SLA, WUE and LWC, indicated the strong impacts of leaf morphology on the gas exchange physiology. The SLA was also related to gas exchange traits both among species and functional groups, while the LWC was only among species and LA among functional groups. In conclusion, significant differences in these functional traits among species suggest that these species could vary in resource use and growth form in their community ecosystem. Also the difference among the functional groups in these traits indicates the resource use of the community would be largely influenced by its species composition, especially the differences of functional groups. The research finding will help to better understanding of the ecosystem function in alpine swamp meadow with related management implication.
