Abstract
The research is devoted to changes of hydrogen peroxide content and peroxydase activity in 30- and 120-days-old Sorghum halepense (L.) Pers plants (long-rhizomed cereal from Poaceae family, which reproduces both by seeds and rhizomes) under growth on substrates from Central enrichment plant "Chervonogradska" dump, with the addition of non-traditional organic and mineral fertilizers - glauconite and wastes of yeast production. As a result of experiments it was established inverse relationship between the peroxidase activity and hydrogen peroxide content in the tissues of 30- and 120-days-old Johnson grass plants that were grown on different substrates. This pattern is natural because under stress conditions is peroxidase activity increased, which activates cleavage of hydrogen peroxide to oxygen and water, thus preventing its toxic effects. It is shown that the 120-days-old S. halepense plant content of hydrogen peroxide and peroxidase activity in most variants were almost at the level of control that is associated with the formation of adaptive changes in the plant for a long existence under stress. After addition non-traditional fertilizers into dump substrates, there were changes in their physical and chemical properties that influenced the content of hydrogen peroxide and peroxidase activity in plants. The experimental data can be the basis for the analysis of plant resistance and creation of performance measures for the adjustment of these plants under technoecosystems, improve their fitoremediation properties by using not only traditional fertilizers but, as shown by our study of non-traditional fertilizers, which will reduce the cost of remediation.
