| Summary: | The activity of the peroxidase enzyme in the leaves of late plum and apple tree varieties growing under controlled
watering and simulated drought conditions was studied. The peroxidase system serves as a unique indicator of
the stress state of plants and provides sufficient information on their physiological state and is a criterion for their
resistance to abiotic factors. It was shown that in the leaves of trees grown under water deficit conditions, a higher
increase in peroxidase activity was observed compared to the control. The highest level of enzyme activity was
found in the leaves of the studied apple varieties. Studies conducted on plum and apple trees showed that the activity
of the peroxidase enzyme in the leaves depended on various factors: environmental conditions, the intensity of
metabolic processes occurring in certain phenophases of growth and development of trees, as well as on the biological
characteristics of the varieties.
Keywords: plum, apple, drought, temperature, antioxidant enzyme, peroxidase.
