摘要：The analysis of the available bibliographic data on the influence of hydroxyaryl compounds on the growth and development of grain legume crops grown on different soils is carried out. The content of the hydroxyaryl compounds in various types of soils has been studied. Their maximum amount in the chernozem soils has been defined. A decrease in the amount of the hydroxyaryl compounds with an increase in the depth of sampling was revealed. The quantitative content of the polyphenol oxidase enzyme has been established in the seeds of winter wheat variety Grom. The effect of hydroxyaryl compounds of exogenous plant origin on the development of winter wheat seeds in various soil conditions has been analyzed. The soils rich in hydroxyaryls are more favorable for seed growing and development. The options with the use of exogenous hydroxyaryl compounds of plant origin and chernozem had the maximum stimulating effect, while sand samples had the minimum one.
