Bacteria-induced systemic resistance and growth promotion in Glycine max L. Merrill upon challenge inoculation with Fusarium oxysporum

摘要: In the present study, two bacterial strains along with Pseudomonas sp. strain VS1 were employed and screened on basis of plant growth-promotion characteristics. Strains showed in vitro antibiosis against test fungal pathogen Fusariumoxysporum together properties that included indole-3-acetic acid, 1-aminocyclopropane-1-carboxylic acid inorganic phosphorus solubilization production. The activities stress responsive enzymes lipoxygenase, phenylalanine ammonia-lyase, catalase, peroxidase superoxide dismutase reported bacteria control-treated soybean plants. Bacteria treated seeds higher enzymatic leaves comparison spore considered as positive control. Treatment resulted remarkable increase chlorophyll content compared to water (negative control) (P < 0.05). Soybean subjected at 0 day after seeding, SJ5 significantly enhanced emergence 28 days seeding than other fresh weight both shoot root was increased when presence spores dry weights roots shoots by treatments control Strain length a number lateral suspension applied seeding. Moreover, plants exhibited greater
