摘要

与外生菌根真菌(EMF)的共生关系对包括针叶树在内的许多木本植物的生存和生长至关重要。早期树木生长是干扰环境下幼苗存活和长期建立的关键预测指标。在虫害、病原体或干旱等非生物干扰和金属污染等干扰之后,针叶树人工林的有效再生需要确定在特定场地条件下能够与目标针叶树宿主定殖并建立共生关系的EMF物种。因此,几十年来,针叶树寄主与EMF共生体之间的相互作用一直是研究和森林管理的焦点。在不同环境条件下进行的针叶树-电磁场相互作用的实验研究产生了不一致的结果,使标准化管理协议的建立复杂化。我们进行了系统的荟萃分析,以量化特定EMF物种促进松树(松)和云杉(云杉)属针叶寄主生长和抗逆性的程度。我们进行了全面的文献检索,以确定用单一EMF菌株接种松树和/或云杉物种的实验研究,并测量了反映树木生长和/或抗应力的参数。在检索到的1806篇文章中,32篇研究生长效应的研究和26篇评估抗逆性的研究符合定量分析的纳入标准。荟萃分析显示,电磁场接种显著促进针叶树生长,而对抗逆性的影响无统计学意义。这些发现强调了EMF通过改善生长结果来支持森林更新和恢复工作的潜力,同时强调了进一步研究阐明针叶树-EMF相互作用中抗逆性机制的必要性。

Ectomycorrhizal fungi inoculation of conifers increases growth, but not stress resistance: A meta-analysis
Symbiotic relationships with ectomycorrhizal fungi (EMF) are critical for the survival and growth of many woody plants, including conifers. Early tree growth is a key predictor of seedling survival and long-term establishment in disturbed environments. Effective regeneration of conifer plantations following disturbances such as insect attack, pathogens or abiotic disturbances such as drought, and metal pollution requires the identification of EMF species capable of colonizing and establishing symbiosis with target conifer hosts under given site conditions. Consequently, interactions between conifer hosts and EMF symbionts have been a focal point of research and forest management for decades. Experimental studies of conifer-EMF interactions carried out under diverse environmental conditions have yielded inconsistent outcomes, complicating the establishment of standardized management protocols. We did a systematic meta-analysis to quantify the extent to which specific EMF species promote growth and stress resistance of conifer hosts in the genera Pinus (pine) and Picea (spruce). A comprehensive literature search was conducted to identify experimental studies where pine and/or spruce species were inoculated with a single EMF strain and parameters reflecting tree growth and/or stress resistance were measured. Of the 1806 articles retrieved, 32 studies examining growth effects and 26 studies evaluating stress resistance met the inclusion criteria for quantitative analysis. The meta-analysis revealed that EMF inoculation significantly enhances conifer growth, whereas its impact on stress resistance was not statistically significant. These findings underscore the potential of EMF to support forest regeneration and restoration efforts through improved growth outcomes, while highlighting the need for further research to elucidate the mechanisms underlying stress resistance in conifer-EMF interactions.

期刊介绍: Forest Ecology and Management publishes scientific articles linking forest ecology with forest management, focusing on the application of biological, ecological and social knowledge to the management and conservation of plantations and natural forests. The scope of the journal includes all forest ecosystems of the world. A peer-review process ensures the quality and international interest of the manuscripts accepted for publication. The journal encourages communication between scientists in disparate fields who share a common interest in ecology and forest management, bridging the gap between research workers and forest managers. We encourage submission of papers that will have the strongest interest and value to the Journal''s international readership. Some key features of papers with strong interest include: 1. Clear connections between the ecology and management of forests; 2. Novel ideas or approaches to important challenges in forest ecology and management; 3. Studies that address a population of interest beyond the scale of single research sites, Three key points in the design of forest experiments, Forest Ecology and Management 255 (2008) 2022-2023); 4. Review Articles on timely, important topics. Authors are welcome to contact one of the editors to discuss the suitability of a potential review manuscript. The Journal encourages proposals for special issues examining important areas of forest ecology and management. Potential guest editors should contact any of the Editors to begin discussions about topics, potential papers, and other details.
