title: THE ANTIOXIDANT ENZYMES – INDICATORS OF DIFFERENT XYLOGENESIS SCENARIOS: IN EARLY ONTOGENY AND IN ADULT PLANTS (EXAMPLE OF BETULA PENDULA ROTH)
abstract: We studied the activity of antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT), peroxidase (POD)) and polyphenol oxidase (PPO) across ontogenetic stages during the formation of normal (in silver birch, Betula pendula Roth var. pendula ) and abnormal (in Karelian birch, Betula pendula Roth var. carelica (Mercl.) Hamet-Ahti) wood structure. This was the first study of this sort. The objects were the seedlings (6‑and 11‑weeksold) and adult plants of different forms of the silver birch (
