Effects of various AMF and Bacillus pumilus strain NBRC 12092 on growth of Ocimum sanctum under salinity stress
Nidhi Yadav, Munna Singh
The aim of the present study was to notice the synergistic effect of Arbuscular Mycorrhizal fungi (AMF) and Bacillus pumilus, on the growth of Ocimum sanctum var. CIM-AYU grown under 40 ppm of Sodium fluoride stress. Glomus mossae and Bacillus pumilus strain NBRC 12092 increased leaf fresh weight by 35% and 9.5% respectively. Consortium of Glomus mossae and Bacillus pumilus strain NBRC 12092 (Gm+St 2) resulted in 42% increase in leaf fresh weight of Ocimum sanctum as compared to control. Plant growth promoting rhizobacteria when grown in association with various mycorrhizal fungi showed a remarkable increase in plant height, leaf fresh weight, and total fresh biomass. Best consortium result was shown by G. mossae followed by G. fasciculatum, G. aggregatum and G. intraradices. Inoculation of tulsi seedlings with mycorrhizal fungi and Bacillus pumilus increased the fluoride tolerance level of the herb.
