摘要: Abstract Phosphogypsum (PG) is a by-product of phosphate fertilizer production. This study the first to investigate Bromis inermis and Festuca ovina root morphology colonization with arbuscular mycorrhizal fungi dark septate endophytes (DSE) in pure PG soil cap (soil). Root length density was significantly lower for plants on than both plant species were colonized AMF DSE, frequency intensity PG. Phosphorus (20 times), calcium (35 times) sulphur (50 higher soil; resulting tissue concentrations negatively correlated but not Bromus. Higher fungal Bromus, especially DSE known be prevalent extreme environments, may responsible its better performance relative Festuca.
