Abstract

Plant growth-promoting rhizobacteria are capable of promoting seed germination, plant growth and development by synthesizing phytohormones and enhancing plant nutrient acquisition and utilization. This study was carried out to determine the effects of Bacillus simplex, Bacillus thuringiensis, Bacillus cereus and Bacillus subtilis and 6 unidentified Bacillus ssp. on seed germination and seedling growth of common bean (Phaseolus valvaris). Surface sterilized bean seeds were inoculated with bacteria in centrifuge tubes for 30 minutes. The inoculated seeds were placed in the plates and replaced in a germination chamber at 25 °C for 21 days. At the end of germination test, germination rate, shoot length, root length, dry shoot and root weights were determined. The results showed that Bacillus spp. SZF135 had the highest germination rate, shoot length, root length, dry shoot and root weight. It was concluded that Bacillus spp. had a great potential to enhance seed germination and seedling growth. Further studies are needed to determine the effects of Bacillus spp. on seed yield in bean plants growing under field condition.
