Determination of Superoxide Dismutase and Polyphenol Oxidase Activityin Betula pendula var. carelica (Betulaceae) Wood with Different Degree of Xylogenesis Disturbance
Effect of modifications in experimental conditions for determining superoxide dismutase and polyphenol oxidase activity in xylem and phloem tissues of woody plants by the example of Karelian birch, also known as curly birch, (Betula pendula Roth var. carelica (Mercl.) Hämet-Ahti) was studied. Some minor features of enzyme reactions were taken into consideration while testing the proposed chemical reaction techniques and mathematically evaluating enzyme activity. The multidirectional trends in behavior of superoxide dismutase and polyphenol oxidase enzymes under different birch xylogenesis scenarios are shown. ACKNOWLEDGMENTS The study was carried out within the framework of the Karelian Research Centre of the Russian Academy of Sciences (Forest Research Institute of KarRC RAS) state research assignment and supported by research grant № 19-04-00622 А from the Russian Foundation for Basic Research.
