AB  - Background
Drought is one of the most adverse abiotic factors that affects crop yield. Crop production in a water-limited environment
can be improved by inoculating plants with selected bacterial strains.
Objectives
The aim of this research was to examine the modulation of several antioxidant parameters in soybean plants inoculated
with Bradyrhizobium japonicum and Bacillus megaterium under drought stress.
Methods
Bacterial strains were selected based on osmotic stress tolerance (36% PEG 6000) in liqiud culture. The effect of soybean
inoculation was evaluated in a soil pot experiment under drought stress (7 days withholding water). The effects of
drought stress and inoculation were examined in soybean roots and nodules through guaiacol peroxidase (POX) and
ionically cell-wall bound peroxidase (POD) activity and ABTS˙+ radical cation scavenging capacity.
Results
The obtained results showed a significant influence of inoculation to constitutive and drought-induced antioxidative
parametres in nodules, while this effect in root was evident only during the water deficit. In the inoculated plants, POX
activity increased by 145% in nodules and by 91% in roots, POD activity was elevated by 86% in nodules and by 54%
in roots, while antioxidant capacity was elevated by 75% in nodules and by 60% in roots in respect to well – watered
plants. Significant increase in all tested parameters was not recorded in non-inoculated plants under drought stress.
Selection and application of bacterial strains with genetic potential for increased tolerance to stresses is useful in developing inoculants which would result in enhanced crop production under adverse environmental conditions
