Abstract
In order to manage field crop production, reduce the negative impact of abiotic factors, and increase productivity and product quality, the modern agricultural industry uses chemical compounds analogous to endogenous phytohormones. Some of these substances are physiologically valuable due to their capability to improve the resistance of plants to adverse environmental factors. The increased interest in such preparations can be attributed to their low cost and effectiveness at low concentrations. The effect of a protatrane mixture (a, b, c) on changes in the physiological parameters (growth characteristics; water status) of spring wheat (Triticum aestivum L.) was studied at low concentrations (10−6 and 10−9 g/L) under chloride salinity conditions. The plants were grown under laboratory conditions in a CLF PlantClimatics chamber, in which untreated and chemically treated spring wheat seeds were evaluated for changes in morphological and physiological parameters under salt stress conditions (150 mM NaCl). The analysis of obtained data revealed that protatranes have a positive effect on the morphometric parameters and water status of plants under chloride salinity conditions. Thus, the examined substances decrease the inhibition of growth processes under chloride salinity conditions. The treatment of seeds with the studied substances increases the tissue water content while decreasing the osmotic potential drop in leaves and roots. Irrespective of the mix ratio, protatranes help to improve the plant water status and mitigate the negative effects of chloride salinity on plant growth.
