Biochemical assays. Panel (a) shows the negative control (media without Trichoderma). Panel (b) shows Trichoderma species T1 was positive for phosphate solubilization. Panel (c) shows ammonia production of Trichoderma species T6. Panel (d) shows IAA production by Trichoderma species T6. Panel (e) shows the negative control for siderophore production in media without Trichoderma. Panel (f) shows the T3 and T4 species in the left and right images, respectively. A wide zone appears, which means that those species produce siderophores.
