Abstract

The understanding of how cover crops composed of native plant species affect soil and berry microbiota within vineyards is not yet elucidated. Through separate bacterial and fungal community profiling of soil and berry samples, the study elucidates the differential effects of cover crop mixtures on microbial communities within a Moscatel Galego vineyard. The results indicate distinct microbial habitats in soil and berries, each harbouring specific sets of microbes. Soil samples exhibit higher species richness compared to berries, with notable differences in taxonomic profiles between the two habitats. Cover crop species mixtures exert significant effects on soil microbial communities, as evidenced by canonical analysis and PERMANOVA tests. Interestingly, the impact of cover crops on berry microbiota is more nuanced, with fewer indicator species identified compared to soil, which may be due to the incomplete establishment of the cover crops. Nevertheless, cover crop treatments indicate some influence on berry microbiota composition, particularly in treatments featuring grasses and legumes. Identifying cover crop mixture-sensitive operational taxonomic units (cmsOTUs) further highlights the specific microbial taxa influenced by different cover crop species mixtures. Analysis of co-occurrence patterns within microbial communities reveals distinct networks for soil and berry microbiota, with cover crop-sensitive OTUs agglomerating according to cover crop mixtures in soil. Conversely, the berry microbiota network exhibits fewer distinct modules, suggesting a broader impact of cover crop mixtures on microbial communities. By elucidating the impacts of cover crop species mixtures on microbial communities, this research contributes to the development of sustainable vineyard management practices aimed at enhancing soil health and grapevine physiology.

探索覆盖作物对莫斯卡塞尔加莱戈葡萄园土壤和浆果微生物群的影响：对可持续葡萄栽培的启示

对由本地植物组成的覆盖作物如何影响葡萄园内土壤和浆果微生物群的理解尚未阐明。通过对土壤和浆果样品进行单独的细菌和真菌群落分析，该研究阐明了覆盖作物混合对莫斯卡特尔加莱戈葡萄园内微生物群落的差异影响。结果表明，土壤和浆果中有不同的微生物栖息地，每个栖息地都有特定的微生物群。土壤样品的物种丰富度高于浆果，两种生境的分类特征差异显著。典型分析和PERMANOVA检验表明，覆盖作物物种混合对土壤微生物群落有显著影响。有趣的是，覆盖作物对浆果微生物群的影响更为微妙，与土壤相比，确定的指示物种较少，这可能是由于覆盖作物的不完全建立。然而，覆盖作物处理表明对浆果微生物群组成有一定影响，特别是以禾草和豆类为主的处理。确定覆盖作物混合敏感操作分类单位（cmsOTUs）进一步突出了受不同覆盖作物物种混合影响的特定微生物分类群。微生物群落共现模式分析揭示了土壤和浆果微生物群的不同网络，覆盖作物敏感的otu根据土壤中覆盖作物的混合而聚集。相反，浆果微生物群网络显示出较少的不同模块，这表明覆盖作物混合对微生物群落的影响更广泛。通过阐明覆盖作物物种混合对微生物群落的影响，本研究有助于发展可持续的葡萄园管理实践，旨在改善土壤健康和葡萄生理。

期刊介绍： Agriculture, Ecosystems and Environment publishes scientific articles dealing with the interface between agroecosystems and the natural environment, specifically how agriculture influences the environment and how changes in that environment impact agroecosystems. Preference is given to papers from experimental and observational research at the field, system or landscape level, from studies that enhance our understanding of processes using data-based biophysical modelling, and papers that bridge scientific disciplines and integrate knowledge. All papers should be placed in an international or wide comparative context.
