The Alien Invader, Rhus typhina L., Outperforms Its Native Competitor in the Scenario of Nitrogen Deposition and Arbuscular Mycorrhizal Fungi (AMF) Inoculation

Nitrogen deposition has been proven to facilitate the establishment of alien plants. Previous studies have certified that nitrogen enhances resource availability habitats and promotes growth invaders. Arbuscular mycorrhizal fungi (AMF) symbiose with vascular plants assist in nutrient acquisition. AMF colonization be another driving factor plant invasion. However, few integrated inoculation into exploration on invasion mechanism. Based a trait approach, present study subjected invader, Rhus typhina L., its co-occurring native species, Acer truncatum Bunge, compared phenotypic variation aboveground belowground traits an inter-specific competition experiment. Through effects different infection functional R. A. truncatum, symbiosis between abiotic factors interspecific relationships were analyzed. We found stimulated typhina, however, decreased rate truncatum. Correspondingly, significantly reduced as morphological including height crown area, root length, surface volume, number tips, tip branches cross for promoted shoot rather than affected length area after mixture planting two species. The chlorophyll content without inoculation, while enhanced net photosynthetic typhina. invader outperforms competitor simulated scenario fluctuation facilitates establishment. speculate extension rhizosphere and, thus, accelerates
