is an edible ectomycorrhizal mushroom of considerable economic value. Its cultivation has become popular in recent years, but there are few studies on the factors affecting its productivity. In this work, the ascoma production and the ectomycorrhizal (ECM) community of a plantation, established in an intensive farming area where this truffle is not naturally present, were studied. production drastically declined from 2016 to 2021, and ascomata of other species ( and ) were found from 2017. Molecular characterization of ectomycorrhizae carried out in 2016 identified 21 ECM fungal species, of which (22%) and (19%) were the most abundant. ectomycorrizae (16%) were almost entirely confined to the fruiting points. The diversity and structure of the ECM community on were significantly different from those observed on hardwood trees. The obtained results suggest that (a native of the study site) tends to replace through a mechanism of competitive exclusion. Although cultivation is possible in suboptimal environments, particular care should be taken to limit competition with ECM fungi more suitable for local conditions.
是一种具有相当经济价值的可食用外生菌根蘑菇。近年来其栽培已变得流行，但关于影响其生产力因素的研究很少。在这项工作中，对一个种植园的子实体产量和外生菌根（ECM）群落进行了研究，该种植园建立在一个集约化农业区，此地并非该松露的自然生长地。从2016年到2021年，产量急剧下降，并且从2017年起发现了其他物种（和）的子实体。2016年对外生菌根进行的分子特征分析鉴定出21种ECM真菌物种，其中（22%）和（19%）最为丰富。外生菌根（16%）几乎完全局限于结果点。上的ECM群落的多样性和结构与在硬木树上观察到的显著不同。所得结果表明（研究地点的本地物种）倾向于通过竞争排斥机制取代。尽管在次优环境中可以进行栽培，但应特别注意限制与更适合当地条件的ECM真菌的竞争。
