Fig. 2From: Mechanisms of the IAA and ACC-deaminase producing strain of Trichoderma longibrachiatum T6 in enhancing wheat seedling tolerance to NaCl stressEffect of different concentrations of NaCl solutions on (a) IAA concentration and (b) the activity of ACC-deaminase in Trichoderma longibrachiatum T6. The line bars represent the standard errors of the means. Different letters denote significant difference at the P < 0.05 level by Duncan’s new multiple range test (n = 12)Back to article page
