Abstract
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.
Highlights
Nowadays, biologization of technological production processes, that is, effect of biologically active substances on the agrocenosis, in order to reduce the pesticide effect and increase the productivity of the agricultural crops is a relevant direction of the agricultural development
Based on the mentioned above, the aim of the work was: to determine the content of the hydroxyaryl compounds in different types of soil and in winter wheat seeds; to reveal the joint effect of soil polyphenols, including those formed as a result of vital activity, on the ontogenesis of higher plants, as well as the possibility to use them as a source of energy for germination of seeds of Triticum aestivum L
The analysis of the greenhouse experiment was carried out according to the following indicators: the content of the hydroxyaryl compounds in the soil, the activity of polyphenol oxidase in the seeds of winter wheat, their germination, the length and weight of winter wheat seedlings
Summary
Biologization of technological production processes, that is, effect of biologically active substances on the agrocenosis, in order to reduce the pesticide effect and increase the productivity of the agricultural crops is a relevant direction of the agricultural development. Active substances of various chemical composition and origin are widely represented both in the soil as in the plants. One of the most important fields of the research is a study of soil phytotoxicity, which is a result of the phenolic substances accumulation in it [2]; they were found at various levels of biological systems. These substances are able to regulate various processes of plant life, including metabolic processes and cell division regulation. The non-commercial part of the crop, including the husks, can be used as a source of hydroxyaryl compounds for various purposes [5]
