Endophytic fungal isolates showing phosphate solubilisation on Pikovskaya’s agar media plates incubated at 25 ± 2 °C (a) No P-solubilisation; (b) P-solubilisation as indicated by presence of clear zone around fungal stub and (c) quantitative analysis of IAA production by different endophytic fungal isolates. Values are the mean from three replicates ± SD. Different lowercase letters denote significant differences at P ≤ 0.05 analyzed by the Duncan test in SPSS 16.
