Vineyards in southern Brazil have high copper levels due to the application of products to control fungal diseases. High soil concentrations of this element can have toxicity to young plants. Arbuscular mycorrhizal fungi (AMF) can alleviate this effect, but the beneficial effect depends on the plant and AMF. AMF have different ecological strategies and respond differently to environmental and management variables. We analyzed AMF species richness, root mycorrhizal colonization, and soil physicochemical attributes in soil and grapevine root samples from vineyards with different growing times (<10, between 30 and 40 and < 60 years old) from Vale da Uva Goethe, Southern Brazil. There were higher phosphorus levels, copper, potassium, and organic matter in the 60 year old vineyard than in the other two vineyards. That affected mycorrhizal colonization, which reached 87% in the oldest vineyard, and 27% in the youngest, 10 year old vineyard. The lowest AMF richness in the oldest vineyard, with nine species, had a correlation with the high levels of copper, phosphorus, and potassium. The Glomeraceae family had the highest occurrence in this environment. In the youngest vineyard, which had 16 AMF species, the low pH was linked to species of Acaulosporaceae, which did not occur in the oldest vineyard. Glomus ambisporum was the dominant species, and high soil copper levels and pH above 6.0 were negatively related to the presence of AMF species of Acaulosporaceae. We conclude that in high-copper soils there is an increase in mycorrhizal root colonization and a predominance of ruderal AMF species, such as those of the Glomeraceae family.

由于将产品用于控制真菌疾病，巴西南部的葡萄园铜含量很高。土壤中高浓度的这种元素可能对幼小的植物产生毒性。丛枝菌根真菌（AMF）可以减轻这种作用，但有益作用取决于植物和AMF。AMF具有不同的生态策略，并且对环境和管理变量的反应也不同。我们分析了巴西南部Vale da Uva Goethe不同生长时间的葡萄园（<10，30至40至60岁之间）的土壤和葡萄根样品中的AMF物种丰富度，根菌根定植和土壤理化属性。60年历史的葡萄园中的磷，铜，钾和有机质含量高于其他两个葡萄园。这影响了菌根定植，最古老的葡萄园达到了87％，而最年轻的10岁葡萄园达到了27％。最古老的葡萄园中，AMF含量最低，只有9种，与铜，磷和钾的含量高有关。在这种环境下，glomeraceae家族的发病率最高。在拥有16种AMF物种的最年轻的葡萄园中，低pH值与Acaulosporaceae的物种有关，而在最古老的葡萄园中则没有。Glomus ambisporum是优势种，土壤铜含量高和pH值高于6.0与棘孢科AMF物种的存在负相关。我们得出的结论是，在高铜质土壤中，菌根根定植量增加，而鱼AMF物种（例如Glomeraceae家族）则占主导地位。
