“…Hence, there is an opportunity to develop substances that are effective in combating bacteria, safe to use with the plants and possibly beneficial for the health of the potato when affected by the phytopathogenic gram-positive bacterium Cms. Bio-composites of fungal origin avoid both the environmental risks associated with modern chemical pesticides and the increasing resistance of phytopathogens to chemical pesticides [7]; phytopathogens decrease both the yield and quality of these strategically important crops [8]. Therefore, the most satisfactory solution would be to identify preparations based on natural compounds.…”

The effect of metal (II)-containing composites based on extracellular metabolites of basidiomycetes Pleurotus ostreatus, Ganoderma lucidum, Grifola umbellata and Laetiporus sulphureus on the viability and response of potato plants in vitro has been investigated. The Lukyanovsky variety of potato, which is susceptible to ring rot, caused by the bacterium Clavibacter sepedonicus, was studied. The parameters investigated included biofilm formation by Clavibacter sepedonicus, various morphometric parameters of plants and the phytotoxicity of substances of fungal origin. The greatest anti-biofilm-forming effect was observed in metal-containing biocomposites based on G. lucidum; Fe- and Co-containing biopreparations inhibited the formation of Clavibacter sepedonicus biofilms by 40–50%. The plant height was adversely affected by composites, in the absence of metal (II), derived from L. sulphureus and P. ostreatus, as well as by a Co-containing composite derived from P. ostreatus. The decrease in plant growth, in comparison with the control, can be associated with the pronounced antibiotic properties of these basidiomycetes and cobalt. The remaining biocomposites studied did not have an adverse effect on the growth of potatoes in vitro. A number of morphometric parameters (length of internodes, number of leaves) remained virtually unchanged when exposed to biocomposites of fungal origin. In contrast to the vegetative part of plants, the biomass and length of the roots increased by 10–20% under the influence of biocomposites. Copper-containing composites derived from G. lucidum had no phytotoxic effect on plants and enhanced potato resistance to Clavibacter sepedonicus. The beneficial properties of biocomosites may be judged by the degree of stimulation of the physiological processes underlying the formation of the underground part of the plants, which is a prerequisite for increasing yields. The biocomposites are environmentally friendly because of their natural origin and being effective at very low doses. The results obtained using metal-containing biocomposites derived from G. lucidum and Gr. umbellata demonstrate the safety and possible improvement in health of potato plants by using biocomposites derived from cultures of higher fungi.

Goal. The effect of fungicides on the dynamics of the activity of peroxidase, catalase (CAT) and chlorophyll content in lupine plants during seed dressing has been established. Methods. Laboratory and vegetation researches were conducted in the laboratory of analytical chemistry of pesticides of the Institute of Plant Protection. Yellow lupine (Lupinus luteus L.), variety Obriy has been grown. The objects of research were fungicides triticonazol (40 g/t) and its combination with prochloraz (120 g/t). Determination of the content of fungicides in plants was carried out using chromatographic methods according to officially approved methods and methods developed in the laboratory of analytical chemistry of pesticides. Chlorophyll content and peroxidase activity were measured by colorimetric method, catalase activity — by titrimetric method. Results. According to the research results, the varying sensitivity of the enzymatic system of antioxidant defense (catalase, peroxidase) in response to seed dressing by fungicides was recorded. It showed that on the 10th day after sowing, content of triticonazol in plants was 0.8 mg/kg, and the peroxidase activity was similar to that in untreated plants. Subsequently, against the background of a decrease in the content of the active substance, a gradual activation of the enzyme was observed. Catalase activity also gradually increased beginning from the 14th day, and on the 30th day it exceeded the corresponding control indicator by 40%. When using a combination of triticonazol with prochloraz, the disturbance in the balance of peroxidase catalase was more significant. However, by the phase of 7—8 leaves, with a minimal total content of fungicides (0.38 mg/kg), the enzyme activity approached the control level, which is associated with the restoration of plant homeostasis and the formation of its adaptive potential under stress conditions. The stimulating effect of these fungicides on chlorophyll content at the initial growth stages of lupine was established. The chlorophyll concentration in fungicides-treated plants exceeded the control indicator by 11—29%. Conclusions. The use of systemic triazole fungicides to protect seedlings, improves the photosynthetic activity of plants and at the same time acts as a stress factor that activates protecting enzymes (catalase, peroxidase), which trigger the development of protective adaptive reactions of plants.

The Impact of Short-Wave UV Radiation on Peroxidase Activity in Soft Wheat Seeds

The effect of UV radiation on plants provokes oxidative stress, accompanied by the production of reactive oxygen species that can have a direct destructive effect on cellular structures and initiate free radical oxidation of proteins, lipids, and nucleic acids. There is an antioxidant defense system in plant cells that includes a complex of low and high molecular weight compounds. Antioxidants with high molecular weight are enzymes, the key of which is peroxidase [PO]. The paper studies changes in PO activity in soft spring wheat seedlings due to grain treatment with small and medium doses of short-wave UV radiation. A UV-dosed irradiation system (Bio-Link Vilber) with the exposure time 0–60 minutes in increments of 10 minutes was used for seed treatment. Pre-soaked wheat seeds were germinated in Petri dishes. PO activity was determined colorimetrically in three-day-old wheat seedlings, according to A. L. Boyarkin [3]. When the source was irradiated for up to 30 minutes, a clear dependence of the PO activity on the exposure time was not established. The maximum increase in peroxidase activity (by 25.9% relative to the control) was detected with 30-minute UV irradiation. A further increase in exposure time led to a significant decrease in enzyme activity. Moreover, vital feedback was revealed between the activity and exposure time in the range of 30–60 minutes.
