摘要

许多研究通过测试杀菌剂是否影响植物的生存、生长、生物量和/或多样性来研究植物与病原体的相互作用。在这里，我们综合了这些研究，对62篇论文中的369个实验进行了荟萃分析，这些实验比较了使用杀菌剂处理的植物和未处理的对照植物。总体而言，杀菌剂增加了本地植物物种的存活率和群落生物量，但减少了多样性，反映了隔离脊椎动物食草动物的效果。对植物生长没有总体影响。然而，对数据子集的分析揭示了一个更加多样化和复杂的图景，几乎没有一致的结果。抽样的强烈地理偏差和许多变量组合的小样本量使得很难区分对这种杀菌剂效果变化的不同解释。总体而言，结果与真菌病原体在维持群落多样性中的作用基本一致，但与纬度生物相互作用假说不一致。未来的研究应旨在填补研究地域分布的空白，尽可能规范方法，并利用分子技术表征杀菌剂处理对目标和非目标生物的影响。

Fungicide effects on wild plants: insights from a global meta-analysis

Many studies have investigated plant–pathogen interactions by testing whether fungicides affect plant survival, growth, biomass, and/or diversity.
Here, we synthesize these studies using a global meta-analysis of 369 experiments from 62 papers that compared plants treated with fungicide to untreated controls.
Overall, fungicide increased the survival of native plant species and community biomass but decreased diversity, mirroring the effects of fencing out vertebrate herbivores. There was no overall effect on plant growth. However, analyses of subsets of the data revealed a more varied and complex picture, with few consistent results. Strong geographical biases in sampling and small sample sizes for many combinations of variables make it difficult to distinguish between alternative explanations for this variation in fungicide effects.
The results, overall, are largely consistent with a role for fungal pathogens in the maintenance of community diversity, but not with the latitudinal biotic interaction hypothesis. Future studies should aim to fill the gaps in the geographical spread of studies, standardize the methods as far as possible, and use molecular techniques to characterize the impacts of fungicide treatments on both target and nontarget organisms.

期刊介绍： New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
