豆科植物–根瘤菌互利共生系统影响因素分析

The Analysis of Factors Influencing Legumes-Rhizobium Mutualism Systems

豆科植物与根瘤菌组成的互利共生系统是典型的共生系统代表之一,本文基于已有的文献资料,通过Meta分析对其加以整合、分析,建立Meta回归模型。根据模型选择AICc准则选出最优模型,基于权重结果分析各因素以及它们的交互效应的重要性。结果表明,控制措施、施肥与否以及它们之间的交互作用是影响豆科植物–根瘤菌互利共生合作系统的重要因素。

Symbiotic system composed of legumes and rhizobia is one of the typical symbiosis representa-tives. Based on existing literature, we analyze and integrate them by Meta-analysis and establish Meta regression models. We select the optimal model according to AICc model selection criterion and analyze the importance of various factors and their interaction based on the result of the weight. The results show that measured effect, fertilization and the interaction between them is the important factor influencing symbiotic cooperative system composed of legumes and rhizobia.
