Aim. The usage of biotic elicitors for elicitation of defense responses may induce plant disease resistance and prevent increased environmental pollution by pesticides. Hydrogen peroxide (HP) is a signal molecule for photosynthetic status and for stomatal movements, and systemic acquired resistance to pathogens in plants proposed to be dependent on H2O2. It is shown in our previous research that biotic elicitors influence on H2O2 content in plants. Kojic acid inhibits tyrosinase activity in melanin synthesis. In plant-pathogen interaction melanin plays role for filaments growth of fungal agent. The aim of research was to analyze in field trials effect of kojic acid with additional donor NO treatment of winter wheat under biotic stress. Methods. Content of endogenous H2O2 was measured in kojic acid and NO donor treated wheat plants (cv. Legenda Myronivska) during different ontogenesis phases. The extent of morphometric parameters and yield structure were analyzed. Results. The data obtained suggest that kojic acid and donor NO decreased the HP content in wheat leaves and increased the grain number and yield. Conclusions. Kojic acid with donor NO is effective combination and could be used as biotic elicitor. Keywords: winter wheat, kojic acid, NO, biotic elicitors, induced resistance, Triticum aestivum L., Septoria tritici Rob.et Desm.

Aim. The usage of biotic elicitors for elicitation of defense responses may induce plant disease resistance and prevent increased environmental pollution by pesticides. Hydrogen peroxide is a well-known signal molecule for photosynthetic status and for stomatal movements, and systemic acquired resistance to pathogens in plants proposed to be dependent on H2O2. The aim of research was to analyze in field trials the effect of oxalic, ferulic and kojic acid on H2O2 content and winter wheat resistance against Septoria tritici. Methods. Content of endogenous H2O2 was measured in elicitor treated and inoculated by S. tritici wheat plants (cv. Oberig) during different ontogenesis phases. The extent of disease development, morphometric parameters and yield structure were analyzed. Results. It is shown that the lowest level of hydrogen peroxide in leaves at the necrotrophic stage of pathogen infection was after oxalic acid treatment, and the highest – after koijc acid influence. Conclusions. The data obtained suggest that elicitors induced defense responses in winter wheat against S. tritici and hydrogen peroxide content is an important and valuable parameter.

Aim. The usage of biotic elicitors for elicitation of defense responses may induce plant disease resistance and prevent increased environmental pollution by pesticides. The aim of research was to analyze in field trials participation of ferulic acid in elicitation of winter wheat resistance against Septoria tritici blotch agent. Methods. Content of endogenous H2O2, peroxidase, catalase and ascorbatperoxidase activities were measured in elicitor-treated and inoculated by S. tritici blotch winter wheat plants (cv. Poliska 90) during different ontogenesis phases. The extent of disease development, morphometric parameters and yield structure were analyzed. Results. The data obtained suggest that ferulic acid induced defense responses in winter wheat against S. tritici blotch agent. Initiation of defense responses in elicitor-treated plants occurred shortly. Hydrogen peroxide content was enhanced in elicitor-treated plants. Conclusions. Ferulic acid could be used as biotic elicitor. It increased the wheat grain quantity. Elicitation of biochemical nature of induced defense responses revealed increased peroxidase activities for lignin biosynthesis and mechanical strengthening of the plant cell walls. Keywords: winter wheat, biotic elicitors, induced resistance, ferulic acid, Triticum aestivum L., Septoria tritici.

Aim. The aim is to research the ability of enhancing ferulic acid effect as a biotic elicitor to induce tolerance of winter wheat plants against Septoria tritici Rob et Desm. leaf blotch infection by addition donor of NO signal molecule. Methods. Content of endogenous H2O2 was measured in wheat leaves (cv. Oberig myronivskij and Svytanok myronivskij). The extent of disease development, morphometric parameters and yield structure were analyzed. Results. It is shown that combination of treatment by ferulic acid with NO donor reduced the disease symptoms on 1–2 points. The level of endogenous hydrogen peroxide increased on 27 % in cv. Svytanok myronivskij. Conclusions. The data obtained suggest that combination of ferulic acid with donor NO could be used as more effective combination than biotic elicitor. They decreased the degree of lesions in leaf area caused by Septoria tritici Rob et Desm. leaf blotch infection and stimulated the growth of wheat plants. The analyze of biochemical mechanisms revealed that system resistance of wheat plants is induced via activation of antioxidant protection.

Ecdysteroids (ECs) are steroid hormones originally found in the animal kingdom where they function as insect molting hormones. Interestingly, a relatively high number of these substances can also be formed in plant cells. Moreover, ECs have certain regulatory effects on plant physiology, but their role in plants still requires further study. One of the main aims of the present study was to verify a hypothesis that fenarimol, an inhibitor of the biosynthesis of ECs in the animal kingdom, also affects the content of endogenous ECs in plants using winter wheat Triticum aestivum L. as a model plant. The levels of endogenous ECs in winter wheat, including the estimation of their changes during a course of different temperature treatments, have been determined using a sensitive analytical method based on UHPLC-MS/MS. Under our experimental conditions, four substances of EC character were detected in the tissue of interest in amounts ranging from less than 1 to over 200 pg·g−1 FW: 20-hydroxyecdysone, polypodine B, turkesterone, and isovitexirone. Among them, turkesterone was observed to be the most abundant EC and accumulated mainly in the crowns and leaves of wheat. Importantly, the level of ECs was observed to be dependent on the age of the plants, as well as on growth conditions (especially temperature). Fenarimol, an inhibitor of a cytochrome P450 monooxygenase, was shown to significantly decrease the level of naturally occurring ECs in experimental plants, which may indicate its potential use in studies related to the biosynthesis and physiological function of these substances in plants.
