基于meta分析的丛枝菌根对小麦产量和品质的影响
Meta-analysis of the effects of arbuscular mycorrhizae on the yield and quality of wheat
摘要
Abstract
Wheat (Triticum aestivum) is one of the most important grains cultivated by humans,and as such,it plays a key role in ensuring food security. Achieving higher and more stable yields and better quality of wheat grains is an important scientific issue. Arbuscular mycorrhizae (AM) are the most widespread symbionts in plant roots,and can improve plant nutrition,yield,and quality. Many studies have demonstrated that AM can promote wheat plant growth and improve grain yields. In this study,a meta-analysis was conducted to evaluate the effects of AM fungi on the grain yield and quality of wheat based on 171 published reports. This allowed for the systematic and comprehensive evaluation of the roles of AM in wheat production and the identification of AM fungi species or genera that consistently increase wheat grain yield and quality. The results of the meta-analysis indicated that AM can increase wheat grain yield by up to 24.2％ as a result of increasing grain number per spike (by up to 17.1％) and the thousand-grain weight (by up to 15.7％). In addition,AM can improve wheat quality by increasing protein content (by up to 15.7％) and the contents of nutrients such as phosphorus and zinc (by up to 15.2％ and 21.5％,respectively). Improvements in the yield and quality of wheat grains by AM may be attributed to the improvement of wheat shoot nutrition and leaf chlorophyll content,because AM can increase the concentrations of nitrogen,phosphorus,calcium,and zinc by up to 8.4％,16.2％,91.2％,and 11.3％,respectively,in the shoots of wheat plants,and the leaf chlorophyll content by up to 27.5％. Furthermore,different genera or species of AM fungi have significantly different effects on wheat yield and quality,and those in the genus Funneliformis have more significant and stable effects on wheat grain yield and quality. In summary,this study comprehensively evaluated how and to what extent AM affect wheat grain yield and quality,and identified which AM fungi consistently promote wheat plant growth and grain yield and quality. These results provide a theoretical and practical basis for the application of AM in wheat production and the selection of the best AM fungi to improve wheat grain yield and quality.关键词
