Abstract
The aim of the present study was to assess the synergistic effects of Arbuscular Mycorrhizal fungi (AMF) and Bacillus pumilus, on growth parameters of test plant Ocimum basilicum grown under 40 ppm of Sodium fluoride stress. Plant growth promotory rhizobacteria when grown in association with various mycorrhizal fungi showed a remarkable increase in plant height, leaf fresh weight, leaf dry weight and total fresh biomass. Glomus mossae and Bacillus pumilus strain NBRC 12092 increased leaf fresh weight by 21.5% and 18% respectively as compared to control. Whereas, consortium of Glomus mossae and Bacillus pumilus strain NBRC 12092 (Gm+St 2) resulted in 24% increase in leaf fresh weight of Ocimum basilicum as compared to control. Best consortium results were shown by G. mossae followed by G. fasciculatum, G. intraradices and G. aggregatum. Inoculation of tulsi seedlings with mycorrhizal fungi and Bacillus pumilus increased the fluoride tolerance level of the herb.
