Abstract

The paper investigated the effect of exogenous caffeic acid (0.1 mM) on antioxidant enzyme activity, LPO reactions, the permeability of membranes for electrolytes, the photosynthetic activity and productivity of potato plants (Solanum tuberosum L.) under optimal conditions, as well as under the action of a 2-hour hypothermia of -2 °C simulating chilling. The investigation showed stimulation of the activity of SOD, catalase and peroxidase under the influence of caffeic acid. The research on LPO reactions revealed the absence of the caffeic acid effect on the content of hydroperoxides and a decrease in the accumulation of malonic dialdehyde. Caffeic acid stimulated the photochemical activity of isolated chloroplasts (Hill reaction), and induced an increase in plant productivity. Based on the previous data, the authors made an assumption about the role of phytohormones of auxins in changing physiological and biochemical processes caused by the caffeic acid effect. Hypothermia initiated the development of oxidative stress, increased the electrolyte output, and reduced the activity of light reactions of photosynthesis and the plant productivity. Under hypothermia, caffeic acid made a protective influence on the preservation of membranes as a result of stabilizing oxidative stress and, as a consequence, the light reactions of photosynthesis.
