Development of winter wheat plants under the influence of phenolic compounds

This article analyzes the available bibliographic data on the effect of polyphenolic compounds on the growth and development of grain crops grown on different soils. The content of phenolic compounds in various types of soils has been studied. The maximum amount of phenolic compounds in chernozem soils has been established. A decrease in the amount of phenolic compounds with an increase in the depth of sampling was revealed. In the seeds of winter wheat variety Mironovskaya 808, the quantitative content of phenolic compounds in the amount (50.6 - 50.9 mg / 100 g of wet weight) was determined, the activity of the enzyme polyphenol oxidase was determined, which amounted to 0.96 to 1477 conventional units per gram of fresh weight. The content of exogenous phenolic compounds in buckwheat husk in the amount of 0.1 g per 10 grams of the sample was determined. The effect of phenolic compounds of exogenous plant origin on the development of winter wheat seeds in various soil conditions has been analyzed. The analysis of germination indicators showed the maximum values in the variants with the use of chernozem both in the presence of their own phenolic compounds and when they were introduced from outside, which amounted to 87.3% and 89.1%, respectively. The stimulating effect was manifested in the analysis of the weight (0.072 g / pc) and linear dimensions of 10-day-old seedlings of winter wheat (162.8 mm / pc). An increase in the content of all variants of phenolic compounds in soil samples affected the content of phenolic compounds in plants. The maximum value was determined in the variant "chernozem with the introduction of phenolic extract" and is 61.0 mg / 100 g of wet weight, the minimum - "sand with watering with clean water" (22.4 mg / 100 g of wet weight). The dynamics of changes in the activity of polyphenol oxidase has a positive correlation with the content of phenolic compounds in the soil and the ground weight of winter wheat. Soils with a high intrinsic content of polyphenolic compounds are more favorable for the growth and development of seeds.
