“…Changes in enzymes' activity and the number of their forms indicate a change in metabolic processes occurring when using herbicides depending on their chemical nature, which provides plant resistance to stress caused by chemicals in the form of herbicides. High specific peroxidase activity and an increased number of multiple forms (14) was caused in soybean leaves by Pivot herbicide, exceeding control by nearly three times; this is confirmed by an increase in adaptive potential of Garmoniya soybean variety plants to this herbicide by reducing the intensity of growth processes regulated by enzymes.…”

“…The resistance of crops to herbicides is also studied by enzyme activity indicators, which naturally bear the role in maintaining metabolism constancy during the period of exposure to various negative factors [12,13]. Enzymes that cause reaction to external factors and play a key role in the use of active oxygen forms are peroxidase and catalase [14,15]. In increasing plants' resistance to adverse environmental factors, a special place belongs to peroxidase [16].…”

The article presents the study results of specific activity and multiple forms of peroxidase and catalase as antioxidant enzymes in leaves and seeds of Garmoniya soybean variety in oxidative stress conditions caused by herbicides. It has been found that herbicides not only destroy weeds, but also have an effect on cultivated plants. Significantly low specific peroxidase activity in soybean leaves was identified in crops treated with Pulsar herbicide. High specific peroxidase activity and increased number of multiple forms (14) in soybean leaves was caused by Pivot herbicide exceeding control by almost three times, which was confirmed by a slowdown in growth and development of soybean plants by reducing the intensity of growth processes and, accordingly, increasing their resistance to withstanding adverse conditions caused by exposure to chemical substances - herbicides. Analysis of specific activity and multiple forms of catalase in soybean seeds of the 2018 and 2019 harvest showed differences in enzyme activity and number of forms depending on the herbicides used. Changes in enzymes’ activity and the number of their forms indicate a change in metabolic processes occurring when using herbicides depending on their chemical nature, which provides plant resistance to stress.

“…These effects include activating the antioxidant defense of plants. Increased CAT activity may indicate increased stress and the ability to adapt through ROS detoxification . Sinegovskaya and Dushko, investigating the role of enzymes in increasing soybean plant resistance to herbicides, state that the increase in CAT activity is related to the oxidative stress provided by herbicides, and this increase is essential for plant resistance.…”

Chemical desiccation in the preharvest of grains and seeds is commonly used in production fields. Using herbicides for this purpose is a viable alternative to reduce beans' exposure to adverse crop conditions. Our objectives were to evaluate (1) the efficacy of herbicides for accelerated defoliation of cowpea, (2) the impact of herbicide application on antioxidant enzyme activity and protein and amino acid contents in seeds, and (3) the effects of different herbicide application schedules on the physiological aspects of seeds. In the first experiment, in addition to the control treatment (without herbicides), seven herbicides and two mixtures were applied at night: diquat, flumioxazin, diquat + flumioxazin, glufosinate ammonium, saflufenacil, carfentrazone, diquat + carfentrazone, atrazine, and glyphosate. Diquat and its mixtures showed greater efficacy in anticipating the harvest. Flumioxazin and diquat alone reduced amino acid content by 61.72 and 51.44%, respectively. The same trend was observed for total soluble proteins. The activity of antioxidant enzymes (CAT, POD, PPO) increased, indicating oxidative stress caused by diquat and flumioxazin. In the second experiment, we tested three application times (6 a.m., 12 p.m., 6 p.m.) with diquat, diquat + flumioxazin, and diquat + carfentrazone. The lowest damage to chlorophyll a was at 6 a.m.; other times reduced photosynthetic pigments and increased carotenoid content. Total soluble sugars decreased by 27.74% with nocturnal application of diquat + flumioxazin. Our data indicate that herbicide use for desiccation affects seed quality. These findings highlight the need for selecting appropriate herbicides and application times. Future research should explore long-term impacts on crop yield and quality.

“…Cytosolic and stromal antioxidant protection is typically activated in the cold and supports cold acclimation (Juszczak et al, , , van Buer et al, , Mir et al, , O'Kane, Gill, Boyd, & Burdon, , Sin'kevich et al, ). Secondary regulation of the response starts, such as the cold acclimation responses, quickly at the end of the cold period.…”

Cold is a major stressor, which limits plant growth and development in many parts of the world, especially in the temperate climate zones. A large number of experimental studies has demonstrated that not only acclimation and entrainment but also the experience of single short stress events of various abiotic or biotic kinds (priming stress) can improve the tolerance of plants to chilling temperatures. This process, called priming, depends on a stress "memory". It does not change cold sensitivity per se but beneficially modifies the response to cold and can last for days, months, or even longer. Elicitor factors and antagonists accumulate due to increased biosynthesis or decreased degradation either during or after the priming stimulus. Comparison of priming studies investigating improved tolerance to chilling temperatures highlighted key regulatory functions of ROS/RNS and antioxidant enzymes, plant hormones, especially jasmonates, salicylates, and abscisic acid, and signalling metabolites, such as β- and γ-aminobutyric acid (BABA and GABA) and melatonin. We conclude that these elicitors and antagonists modify local and systemic cold tolerance by integration into cold-induced signalling cascades.
