Growth and Arbuscular Mycorrhizal Fungal Colonization of Two Prairie Grasses Grown in Soil from Restorations of Three Ages

摘要: I compared growth and arbuscular mycorrhizal fungal (AMF) colonization of two prairie grasses (Wild rye [Elymus canadensis] Little bluestem [Schizachyrium scoparium]), an early- a late-dominating species in restorations, respectively, grown soil from restored prairies differing age, characteristics, site history. There were no consistent patterns between restoration age inorganic nutrients or organic matter. The oldest had higher inoculum potential (MIP) than 2- 12-year-old restorations. However, MIP did not translate into actual for soils the three nor relate to phosphorus availability. significant differences root mass among Wild plants but 2-year-old significantly AMF when it was 12- 17-year-old also soils. correlations shoot biomass, biomass colonization, concentrations P, total N, N:P. rye, N positively correlated with negatively suggesting that this species, mycorrhizae may affect Collectively, these results suggest properties unrelated important determining grasses.
