摘要

目的:丛枝菌根真菌(AMF)可在包括葡萄园在内的可持续农业生态系统中发挥重要功能。增加AMF的多样性有利于促进植物生长和提高对环境变化的适应能力。为了在葡萄园生态系统中有效利用 AMF 群落及其益处,需要更好地了解管理系统如何影响 AMF 群落的组成。此外,有机管理葡萄园中的AMF群落是否有别于传统管理葡萄园中的AMF群落,目前还不得而知:本研究对新西兰马尔堡地区的葡萄园进行了调查,以确定在常规和有机系统中嫁接长相思和黑比诺的不同砧木根部的AMF群落。AMF群落的鉴定基于从收集的葡萄根系建立的诱捕培养物中分离的孢子,以及下一代测序技术(Illumina Miseq)。鉴定出的 AMF 物种/属隶属于 Glomeraceae、Entrophosporaceae 和 Diversisporaceae。结果表明,不同砧木的 AMF 群落组成及其与管理制度的相互作用存在显著差异:这些结果表明,葡萄园管理制度会影响砧木对AMF的吸收,因此有些砧木可能更适合有机栽培,因为它们支持AMF群落。这可以通过支持更高的生物多样性来增加有机系统的效益。

Vineyard management systems influence arbuscular mycorrhizal fungi recruitment by grapevine rootstocks in New Zealand.

Aims: Arbuscular mycorrhizal fungi (AMF) can perform significant functions within sustainable agricultural ecosystems, including vineyards. Increased AMF diversity can be beneficial in promoting plant growth and increasing resilience to environmental changes. To effectively utilize AMF communities and their benefits in vineyard ecosystems, a better understanding of how management systems influence AMF community composition is needed. Moreover, it is unknown whether AMF communities in organically managed vineyards are distinct from those in conventionally managed vineyards.

Methods and results: In this study, vineyards were surveyed across the Marlborough region, New Zealand to identify the AMF communities colonizing the roots of different rootstocks grafted with Sauvignon Blanc and Pinot Noir in both conventional and organic systems. The AMF communities were identified based on spores isolated from trap cultures established with the collected grapevine roots, and by next-generation sequencing technologies (Illumina MiSeq). The identified AMF species/genera belonged to Glomeraceae, Entrophosporaceae, and Diversisporaceae. The results revealed a significant difference in AMF community composition between rootstocks and in their interaction with management systems.

Conclusions: These outcomes indicated that vineyard management systems influence AMF recruitment by rootstocks and some rootstocks may therefore be more suited to organic systems due to the AMF communities they support. This could provide an increased benefit to organic systems by supporting higher biodiversity.
