Exploring the influence of structural characteristics on the stability of bioregulators in natural environmental conditions

Abstract

This research aimed to identify the plant bioregulator with lower environmental risk for improving fruit and grape production through the comprehensive field, laboratory, and computational experiments. Plant bioregulators are compounds playing a vital role in the development of plants, regulating diverse cellular processes. Among these compounds, Ormoroc and Globaryll are widely known formulations extensively applied for improving the quality of crops. However, overusing bioregulators in food production has led to their presence in different water resources, threatening to designate them as severe pollutants of natural resources. Field experiments were conducted to identify which bioregulator improves the quality of selected fruit and grape varieties. The laboratory study involved photolysis and hydrolysis experiments in pure and rain waters, aimed at studying the stability of the mentioned bioregulators under naturally occurring conditions. The laboratory experiments also included the exploration of chemical and biochemical oxygen demand. The computational analysis involved density functional theory calculations and molecular dynamics simulations in investigating how the structural characteristics of the compounds affect their local reactivity properties. The study indicates that the application of Ormoroc improves fruit and grape quality to a greater extent. However, the active component of Ormoroc is less stable under the influence of solar irradiation and water, reducing the likelihood of water pollution.
