Inoculation of Plant Growth Promoting Bacteria Ochrobactrum intermedium, Brevibacterium sp. and Bacillus cereus Induce Plant Growth Parameters

Muhammad Faisal


The impact of chromate resistant bacteria Ochrobactrum intermedium, Brevibacterium sp. and Bacillus cereus was observed on Lens esculenta plant under two different concentration of K2CrO4 (0 and 300 mg ml-1). Bacterial inoculations enhanced the seed germination while chromium alone reduced seed germination (60%) and emergence (10%). About 27 and 21% reduction in root and shoot length was recorded at 300 mg ml-1 of K2CrO4. Chromium salt drastically reduced root and shoot length, number and weight of grains per pod, and number and weight of grains per plant, but bacterial strains enhanced these parameters. Plant accumulates chromium in its root and fewer amounts are transferred into shoot, leaves and pod.
