Evaluation of The Growth-Stimulating Potential of Salt-Tolerant Bacteria Isolated from Saline Soils
Annotatsiya
The growth-stimulating potential of four salt-tolerant Bacillus strains (B. subtilis 7А, 9А, 10А and B. proteolyticus 33S) on cotton (Gossypium hirsutum L.) was studied in vitro. Seed inoculation with the strains significantly increased germination, shoot and root length, as well as fresh and dry weight compared to the control. The most pronounced growth-promoting effect was observed with the B. proteolyticus 33S strain, which increased shoot length by 4.9 cm, root length by 2.72 cm, fresh weight by 0.20 g, and dry weight by 0.03 g relative to the control. The obtained results allow us to recommend the studied strains for further research with the aim of their future use in microbial biopreparations aimed at stimulating plant growth and improving the properties of saline soils.
