Fig. 1From: Response of alfalfa growth to arbuscular mycorrhizal fungi and phosphate-solubilizing bacteria under different phosphorus application levelsMycorrhizal infection rate of alfalfa inoculated with AMF and PSB under different phosphorus application conditions. Different capital letters indicated significant difference in different bacteria treatments under the same phosphorus application conditions(P < 0.05), differences small letters mean significant difference under the same bacteria treatments(P < 0.05). P0, P1, P2, and P3 represent 0 mg kg−1, 50 mg kg−1, 100 mg kg−1, and 150 mg P kg−1, respectively. J0, J1, J2, and J3 represent CK, Fm, Bm, and Fm × Bm, respectivelyBack to article page
