凤仙花（Impatiens glandulifera）或喜马拉雅凤仙花（Himalayan balsam）是欧洲最具入侵性的杂草之一，可严重减少当地植物的多样性。它经常形成连续的单一栽培沿着河岸，但这种逮捕演替的机制在很大程度上是未知的。在这里，我们调查了丛枝菌根（AM）真菌对香脂竞争能力的影响与两个本地植物物种，车前和绒毛草。我们还研究了如何与凤仙花的竞争影响殖民地的叶面内生菌和菌根的其他两个共同发生的本地物种，异株荨麻和大蓟。菌根殖民减少香脂生长时，植物单独生长，但似乎没有什么影响时，香脂经历种内或种间竞争。与香脂的竞争以及菌根的加入对披针叶树的生物量没有影响，表明真菌对后者有利，使其能够有效地与香脂竞争。然而，这不是这样的H。毛状的与此同时，与凤仙花的竞争减少了内生菌的数量和菌根定殖。dioica和C. arvense，导致这些植物对昆虫攻击的敏感性增强。众所周知，喜马拉雅香脂可以降解土壤真菌种群，并且还可以减少邻近植物叶片中的有益真菌。这使得植物能够有效地与自己和其他本地物种竞争，从而导致连续的单一栽培。
Impatiens glandulifera or Himalayan balsam is one of the most invasive weeds across Europe and can seriously reduce native plant diversity. It often forms continuous monocultures along river banks, but the mechanisms of this arrested succession are largely unknown. Here, we investigated the effect of arbuscular mycorrhizal (AM) fungi on balsam competitive ability with two native plant species, Plantago lanceolata and Holcus lanatus. We also studied how competition with Impatiens affects colonisation by foliar endophytes and mycorrhizas of two other co-occurring native species, Urtica dioica and Cirsium arvense. Mycorrhizal colonisation reduced balsam growth when the plants were grown singly, but appeared to have little effect when balsam experienced intra- or interspecific competition. Competition with balsam together with the addition of mycorrhizas had no effect on P. lanceolata biomass, suggesting that the fungi were beneficial to the latter, enabling it to compete effectively with balsam. However, this was not so with H. lanatus. Meanwhile, competition with Impatiens reduced endophyte numbers and mycorrhizal colonisation in U. dioica and C. arvense, leading to enhanced susceptibility of these plants to insect attack. Himalayan balsam is known to degrade soil fungal populations and can also reduce foliar beneficial fungi in neighbouring plants. This allows the plant to compete effectively with itself and other native species, thereby leading to the continuous monocultures.
