- Abstract
Root zone soil and root samples of Flaveria bidentis were collected from the six invasion sites in Hengshui of Hebei Province and arbuscular mycorrhizal (AM) fungi were isolated to investigate their species diversity status. The effects of the dominant AM fungi on the growth and development of F. bidentis were evaluated under pot culture conditions, and the effects of the fungi on transportation and distribution of carbon and nitrogen between F. bidentis and its companion plant Trifolium repens were also determined with compartmentalized culture system. In total, 26 species of AM fungi belonging to 8 genera and 7 species belonging to 5 genera were identified from the soil and roots of the invasive plant, respectively. Among them, Acaulospora laevis, Rhizophagus intraradices, Funneliformis mosseae, and Glomus versiforme were dominant for root zone soil. Inoculation of F. mosseae+R. intraradices+A. laevis had the greatest growth promoting effect on F. bidentis. After being inoculated with AM fungi and treated with 15N or 13C in a compartment culture system, the abundance of 15N and 13C in the stem, leaf and root of F. bidentis were significantly higher than that of T. repens. It was concluded that there was a rich diversity of AM fungi of the invasive plant, and the combination treatment of F. mosseae+R. intraradices+A. laevis could help the invasive plant F. bidentis in transporting carbon and nitrogen from its companion plant T. repens, significantly improving the invasive plant competitiveness and nutritional status, and promoting its invasion and colony establishment.
