Abstract:

The present study was undertaken to isolate endophytic and rhizospheric actinomycetes from Gladilous and to evaluate their plant growth promoting traits. Out of 90 isolates, 40 were from rhizospheric soil and 50 from roots of Gladiolus plants. Sixteen isolates from rhizospheric and 14 from endophytic were observed to produce IAA ranged from 4.3-79.9 µg/ml. Eighteen (20%) isolates were observed to solubilize phosphate in the range of 6.1-64.5mg/100ml. Fifteen (16.6%) isolates displayed siderophore production. Twelve isolates were producing hydroxamate in the range of 5.5 to 39.4µg/ml and nine isolates produced catechol ranging between 12.1-35.3µg/ml. Fifty out of 90 isolates were observed to produce the gibberellic acid ranging from 12.5-50.6 µg/ml. Ten isolates were found to produce HCN and 5 isolates were able to show ACC deaminase activity. The antagonistic activity was displayed by twelve isolates against Fusarium oxysporum. On the basis of PGP traits and antifungal activity, isolate Sc9 was selected for green house study which was presumptively identified as Streptomyces sp. This actinomycete isolate could be used as potential plant growth promoting and biocontrol agent.
