Influence Treatment of Barley Seeds by Genus Bacteria Bacillus on Activity of Components of the Antioxidative System in Roots of Seedlings Under Salt Stress

Type: article
Abstract: It has been studied the activity components of the antioxidative system in barley roots to five strains bacteria Bacillus genus treatment of seeds under salt stress. The data obtained allow to conclude that the higher resistance to salinity (4 % NaCl solution, 24 h) the root system of barley seedlings, which manifests itself in maintaining the speed of growth and development of roots under the action of Bacillus amyloliquefaciens (B. am.) 78 TM, Bacillus subtilis (B. s.) 7 MP and B. s. M 9/6 at a concentration of 105 cells/ml. The protective effect of strain B. am. 78 ТМ accompanied by a significant accumulation of proline, and in the recovery period the accumulation of hydrogen peroxide and increased superoxide dismutase and peroxidase. The protective action of strains of B. s. M 9/6 and B. s. 7 MP is due, in our opinion, significant accumulation of hydrogen peroxide and activation of antioxidant enzymes under stress, and in the period of adaptation the preservation of the high content of hydrogen peroxide compared with stress control.
