The diversity of arbuscular mycorrhizal fungi (AMF) associating with grapevines has been determined previously, yet little is known of how the community in roots is shaped by depth in the soil or where roots occur in different management zones of the vineyard (vine row versus alley). The influence of depth, management zone, and time of year on the community of AMF in grape roots was examined. I also tested the potential influence of the alley vegetation on AMF in grapevines by comparing the taxa amplified from roots of other plants retrieved from the alley surface soil to those from grapevines growing in the same zone. Depth shaped the AMF community in grapevine roots more than the management zone based on dissimilarity among all grapevine samples. Time of the growing season did not, although AMF taxa richness was greater in grapevine roots collected in late summer (veraison) than it was in late spring (bloom). The number of abundant AMF taxa in grapevine roots from the uppermost soil depth in the vine row was substantially lower in late spring than in late summer, and this was related to high soil nitrate in late spring. The alley vegetation comprised primarily grass, and clover plants harbored a different AMF community in roots than did intermingled grapevine roots. The change in the AMF community in a single perennial host (grape) that occurred with depth in this study resulted from a shift among common taxa as opposed to the appearance of unique taxa in the subsoil.

深度构造了从葡萄（Vitis vinifera L.）根部扩增出的丛枝菌根真菌的群落。

先前已经确定了与葡萄藤相关的丛枝菌根真菌（AMF）的多样性，但人们对于根的群落如何由土壤深度形成形状或在葡萄园的不同管理区域中出现根的位置（葡萄行与胡同）了解甚少。 ）。研究了深度，管理区和一年中的时间对葡萄根中AMF群落的影响。我还通过比较了从胡同表层土壤中获取的其他植物的根与在同一地区生长的葡萄树的根系上扩增的分类单元，测试了胡同植被对葡萄中AMF的潜在影响。基于所有葡萄样品之间的差异，深度对葡萄根的AMF群落的影响大于对管理区的影响。生长季节的时间没有 尽管夏末（veraison）采集的葡萄根比春末（bloom）的AMF分类单元丰富度更高。春季晚些时候，从葡萄树行最深处开始的葡萄根中丰富的AMF分类单元的数量明显少于夏季末，这与春季末土壤硝酸盐含量高有关。胡同植被主要由草组成，三叶草植物的根部与混合的葡萄根部具有不同的AMF群落。在这项研究中，一个单一的多年生寄主（葡萄）中的AMF群落发生了深刻的变化，这是由于普通生物分类之间的转移，而不是土壤中独特生物分类的出现所致。春季晚些时候，从葡萄树行最深处开始的葡萄根中丰富的AMF分类单元的数量明显少于夏季末，这与春季末土壤硝酸盐含量高有关。胡同植被主要由草组成，三叶草植物的根部与混合的葡萄根部不同。在这项研究中，一个单一的多年生寄主（葡萄）中的AMF群落发生了深刻的变化，这是由于普通生物分类之间的转移，而不是土壤中独特生物分类的出现所致。春季晚些时候，从葡萄树行最深处开始的葡萄根中丰富的AMF分类单元的数量明显少于夏季末，这与春季末土壤硝酸盐含量高有关。胡同植被主要由草组成，三叶草植物的根部与混合的葡萄根部具有不同的AMF群落。在这项研究中，一个单一的多年生寄主（葡萄）中的AMF群落发生了深刻的变化，这是由于普通生物分类之间的转移，而不是土壤中独特生物分类的出现所致。
