摘要: Abstract Endophytic fungus-tall fescue symbiosis can improve the rhizosphere physical quality, but contribution of oxygen-limited conditions on this change, particularly in semiarid and arid regions has not been established yet. Therefore, objective study was to evaluate effects endophyte-tall quality indicators under different aeration a greenhouse pot experiment. The treatments were seven levels air-filled porosity, AFP (0, 0.025, 0.050, 0.750, 0.100, 0.125 0.150 m3 m−3) sandy loam soil, two genotypes (75C 75B) tall (Festuca arundinacea = Schedonorus arundinaceus Schreb.) each with endophytic fungus Epichloe coenophiala (E+) without endophyte (E−). Soil biophysical properties determined intact soil aggregates from zone: structural stability (by HEMC, high energy moisture characteristic), percent water-stable aggregates, water repellency, basal respiration organic matter. results showed that by decreasing AFP, reducing redox potential
