Influence of Pseudomonas spp. on Okra (Abelomuscus esculantaus L.) growth parameters and antioxidant activities under soil salinity

Year: 2020

Type: article

Abstract: In this study total twenty seven gram negative NaCl tolerant rhizobacterial strains were isolated from disturbed soils of Lucknow districts. The 3 selected sampling sites were Bijnor, Pasi Quila and Babasaheb Bhimrao Ambedkar University Campus, Lucknow, India. The isolates have been investigated for different plant growth promoting and biochemical activities. Based on morphological and biochemical tests the total eight (8) rhizobacterial strains were designated as Pseudomonas spp. Among PGP traits, all 8 Pseudomonas strains were examined for Indole-3-Acetic Acid (IAA) production activity. The bacterialisolate IAA4 produces maximum 21.16±3.24 μg mL-1 of IAA at 100 μg mL-1 tryptophan concentration among Pseudomonas strains. This strain show excellent P solubilization and N fixatation in qualitative assay. The higher amount of NaCl salt in soils positively reduces paddy plant physiology and growth parameters. The IAA4 inoculation in okra seeds significantly (P<0.001) improved plant growth parameters, green pigments and modulate antioxidant activities under pot experimental study
