Change of the catalase and peroxidases activity in leaves of cultivated oats under the influence of the separate and combined impact of salinization and pH-level of the root environment

Some physiological-biochemical indicators in leaves of cultivated oat Avena sativa L are studied. at joint impact of salinization and different рН-levels of the root environment. After 30 min. increase in content of peroxide of hydrogen on all skilled options was indicated. The activity of a catalase and peroxidases has amplified at separate action of the studied factors of the root environment. Against the background of the combined stress in leaves of plants essential increase in activity of these antioxidant enzymes isn't revealed. Perhaps, disbalance between AFK-generate systems and the systems of antioxidant protection at a combination of adverse conditions of the root environment is connected with insufficient amount of time for formation of the adaptive answer. The greatest negative impact on growth indicators of oats was exerted by a combination of salinization and sour reaction of the root environment.
