The influence of succinic acid on the photosynthetic activity of spring soft wheat

Currently, a large number of chemicals of different composition and origin, activating physiological and biochemical processes in plants, is known. Carboxylic acids, including succinic acid, possess biostimulating properties. In this regard, the aim of the research was to study the effect of succinic acid on the photosynthetic activity of spring soft wheat. Objects of research were spring soft wheat ( Triticum aestivum ) and succinic acid ( ethane-1,2-dicarboxylic acid ). The study used field, physiological and statistical methods. Field studies were performed in a stationary experiment on the basis of a five-course grain-fallow crop rotation in the southern forest-steppe zone of Western Siberia. The scheme of the experiment included two factors: a pre-sowing treatment of wheat seeds with an aqueous solution of succinic acid and the use of mineral fertilizers. To assess the impact of the factors at study, the following quantitative parameters used in plant physiology were applied: leaf surface area, photosynthetic potential, growth of the vegetative mass in the main growth phases and development of wheat...
