“…К важным регуляторам жизнеспособности растений относятся фенольные соединения -одни из наиболее распространенных вторичных метаболитов, которые присутствуют во всех клетках и тканях (6,7). Их содержание зависит от видовой принадлежности растений, стадии онтогенеза, условий произрастания и минерального питания (8)(9)(10). Функциональная роль фенольных соединений чрезвычайно разнообразна и связана с процессами фотосинтеза, дыхания, роста и развития растений, а также c устойчивостью к стрессовым воздействиям (6,11,12).…”

“…The ability to accumulate phenolic compounds as important components of the antioxidant system of plant protection can serve as a criterion for high stress factor resistance. In plants adaptive to stress factors a significant increase in the content of phenolic compounds in cells comparing to forms with low viability and adaptive response was revealed [6]. Identifying buckwheat forms with high flavonoid content contributes to the development of adaptive varieties that are resistant to various stress factors of the external environment.…”

Breeding buckwheat varieties with high lavonoids content is one of the priorities at the Federal Research Center of Agricultural Biotechnology of the Far East named after A.K. Chaika. The aim of this study was to find ways of increasing the accumulation of rutin in F. esculentum plants in vitro culture using salicylic acid (SA) and copper sulfate. The effective concentrations and exposures of elicitors, which ensure the maximum content of rutin in the plant tissues of buckwheat microplants, were established as a result of the study. The microplants of the Izumrud × Inzerskaya hybrid synthesized the largest content of rutin (3.27%) under prolonged exposure (24 days) to 6.9 mg L −1 of SA concentrate. Microplants of the Izumrud variety synthesized 2.8% of rutin when exposed to the same SA concentrtion for 2 days. Using SA allowed to increase the accumulation of rutin in F. esculentum plants by 1.7-1.9 times, copper sulfate -by 1.2 times compared with the control. The effect of such treatment, which persists for a long time, makes obtaining buckwheat genotypes with a high level of flavonoid synthesis possible.

Although the entomopathogenic bacteria Bacillus thuringiensis Berliner are well-known bio-agents for regulating the population of leaf-eating pests of agricultural and ornamental crops, other agricultural properties of this microorganism are promising. In this work, the growth-stimulating effect of entomopathogenic strains of B. thuringiensis on Deviz pea plants was studied. The entomopathogenic strains B. thuringiensis 685, 926 and 109-C obtained from the Crimean Collection of Microorganisms of the Crimean Agricultural Research Institute, registered online (http://www.ckp-rf.ru) with number 507484, were used as research material. The morphometric parameters of pea sprouts were evaluated following standard methods. Biochemical parameters of pea sprouts were determined for 10-day-old sprouts. The amylase activity of pea sprouts was determined by photocalorimetry; total acidity was measured by titration using 0.1 n NaOH solution; total water-soluble phenolic compounds were determined by Leventhal titrimetric method. It was found that liquid spore culture of strains B. thuringiensis 685, 926 and 109-C had a stimulating effect on the length of root and stem and the weight of 10-day-old sprouts of Deviz pea variety. Treatment with a spore suspension of all tested strains B. thuringiensis led to an increase in the content of organic acids in the sprouts by an average of 12.4% compared with that of the control. Maximum stimulating effect on amylolytic activity and synthesis of phenolic compounds in Deviz pea sprouts was achieved by treating with a spore suspension of the strain B. thuringiensis 926. The amylase activity increased on average by 41.5% when compared to that of the control, while the total content of phenolic compounds in this experiment was 2.3 times higher than that of the control. Therefore, in light of the entomopathogenic properties and the obtained data on the growth-stimulating activity of the strains of B. thuringiensis, it can be concluded that these bacteria have additional potential for their use in agriculture as a bio-agent for plant protection having a complex action.
