Over the last decades, tillage, chemical fertilizers, and pesticides have reduced the beneficial fungal population size in arable soils. Though soil inoculation can be a practical way to restore arbuscular mycorrhizal fungi (AMF) population size, weeds may also be benefited, as well. This study was aimed to evaluate the effect of three AMF species (Funneliformis mosseae, Rhizoglomus fasciculatum, and Rhizoglomus intraradices) on photosynthetic rate, secondary metabolites content, reproductive organs percentage and nutrient uptake in Solanum nigrum L. and Digitaria sanguinalis L. weed species. Our results showed species variation in response to AMF inoculation, so that, while inoculation with R. intraradices fungal species decreased total biomass in S. nigrum plants significantly, it increased total biomass of D. sanguinalis plants by 26–49%. In addition, inoculation with F. mosseae species increased phenol, anthocyanin, and total terpenoid content in S. nigrum plants much more than D. sanguinalis. Increased photosynthetic rate, secondary metabolites content, and flowering percentage in AMF‐inoculated S. nigrum plants show the enhanced competitive ability and allelopathic potential of this weed when associated with AMF, which makes it a good competitor against other plant species in the environment.

丛枝菌根真菌接种对龙葵和半指洋总酚，花色苷和萜类化合物的含量，光合速率和养分吸收的影响

在过去的几十年中，耕作，化肥和农药减少了可耕土壤中有益真菌的种群数量。尽管接种土壤可能是恢复丛枝菌根真菌（AMF）种群规模的实用方法，但杂草也可能会受益。这项研究旨在评估3种AMF物种（Funneliformis mosseae，Fhizoglomus fasciculatum和Radhigloglos intraradices）对龙葵和Digitaria sanguinalis L.杂草物种的光合速率，次生代谢产物含量，生殖器官百分比和养分吸收的影响。我们的结果表明，接种AMF疫苗后物种会发生变化，因此，R. intraradices真菌物种中降低总生物量龙葵植株显著，它增加的总生物量马唐由26-49％的植物。此外，接种F. mosseae物种比S. sanguinalis增加了S. nigrum植物中苯酚，花色苷和总萜类化合物的含量。与AMF结合后，AMF接种的S. nigrum植物的光合速率，次生代谢产物含量和开花百分比提高，表明该杂草具有增强的竞争能力和化感潜力，这使其成为与环境中其他植物的良好竞争者。
