From 2016 to 2019, 128 organic and conventional spring and winter pea fields in Germany were surveyed to determine the effects of cropping history and pedo-climatic conditions on pea root health, the diversity of Fusarium and Didymella communities and their collective effect on pea yield. Roots generally appeared healthy or showed minor disease symptoms despite the frequent occurrence of 4 Didymella and 14 Fusarium species. Soil pH interacted with the occurrence of the Fusarium oxysporum species complex (FOSC) and F. tricinctum that correlated with reduced or increased soil pH values, respectively. While legumes in the cropping history or reduced time between legumes correlated with occurrence of D. pinodella and to a lesser degree with the members of the F. solani species complex (FSSC), the reverse was true at least in organic spring peas for F. redolens. Only in conventional systems increased root infections with F. redolens and the FSSC were linked to root rot incidence whereas yields negatively correlated with the FOSC and positively with F. tricinctum isolation frequencies. Overall, this study shows that pea root rot pathobiome is rather stable and that the damage caused is mostly due to the interaction with environmental conditions.
2016年至2019年期间，对德国128个有机和传统的春豌豆和冬豌豆田进行了调查，以确定种植历史和土壤气候条件对豌豆根系健康、镰刀菌和壳二孢菌群落多样性及其对豌豆产量的综合影响。尽管频繁出现4种壳二孢菌和14种镰刀菌，但根系总体上看起来健康或仅表现出轻微的病害症状。土壤pH值与尖孢镰刀菌复合种（FOSC）和三线镰刀菌的发生存在相互作用，这两种镰刀菌分别与土壤pH值的降低或升高相关。种植历史中的豆科作物或豆科作物之间较短的间隔时间与柱孢壳二孢菌的发生相关，在较小程度上也与茄病镰刀菌复合种（FSSC）的成员相关，但至少在有机春豌豆中，情况对于变红镰刀菌则相反。仅在传统种植系统中，变红镰刀菌和FSSC导致的根系感染增加与根腐病发病率相关，而产量与FOSC呈负相关，与三线镰刀菌的分离频率呈正相关。总体而言，本研究表明豌豆根腐病病理群落相当稳定，造成的损害主要是由于与环境条件的相互作用。
