Arbuscular mycorrhizal fungi improve the growth and performance in the seedlings of Leymus chinensis under alkali and drought stresses.

ABSTRACT: Alkali and drought stresses are increasing severe environmental problems throughout the world, especially in the Songnen grassland of northern China. Leymus chinensis is the dominant grass species in the Songnen grassland of northern China and the most promising species for grassland restoration. Arbuscular mycorrhizal fungi (AMF) can colonize 80% of vascular plants, which can enhance the growth of host plants and provide extrinsic protection against abiotic stresses. However, little is known about the interaction effect of alkali and drought stresses on plant-AM symbionts. Here, seedlings of Leymus chinensis inoculated with or without mycorrhizae were cultivated in soil with 0, 100 or 200 mM NaHCO₃ under 0, 5 or 10% (w/v) PEG treatment, and the changes in growth,
