| Abstract | The results of studies on effect of the biological product Bioneostim (1.0 l/t) used in various ways with the plant growth regulator Vermistim D (seed treatment before sowing – 7.0 l/t, crop spraying – 8.0 l/ha) on the activity of individual enzymes in the seedbed. Oxidative-reductive transformations are an integral part of plant metabolism, the direction of which is determined by a number of factors, including biological and chemical preparations. Metabolic, physiological-biochemical indicators, such as enzyme activity, chlorophyll content, intensity of organic matter accumulation and respiration, directly depend on the activity of enzymes of the oxidoreductase class: catalase (EC 1.11.1.6), peroxidase (EC 1.11.1.7); polyphenoloxidase (EC 1.14.18.1). The research was conducted in the field conditions of the Department of Biology of Uman National University during 2024–2025. The effect of the biological product Bioneostim and the plant growth regulator Vermistim D was studied оn the Ivolga variety. Field experiments were conducted using a systematic method with three repetitions. Crops in the stem elongation phase were sprayed with the plant growth regulator Vermistim D at a rate of 8.0 l/ha based on a working mixture consumption rate of 200 l/ha. The activity of oxidoreductase enzymes: catalase was determined in the flowering-pod formation phase of the crop. The biological product Bioneostim and the plant growth regulator Vermistim D had a positive effect on the activation of certain enzymes of the oxidoreductase class (catalase, peroxidase, polyphenol oxidase) in plants of the sowing pea, which is a consequence of the intensification of metabolic processes, in which enzymes are active and direct participants. The highest enzyme activity in plants of the sowing chaff was observed with the combined use of the biological product Bioneostim at a rate of 1.0 l/ha with the plant growth regulator Vermistim D at a rate of 7. 0 l/t, followed by spraying Vermistim D at a rate of 8.0 l/ha on this crop background, which exceeded the control by an average of 27–69%. This is obviously a result of the intensification of plant-microbial interactions and improved mineral nutrition of crops, on which the direction of metabolic processes in plants directly depends. | ||
