Abstract

This has been investigated the effect of stress on the maize dehydrogenase mesophyll system of maize leaves. The plants were exposed to cold, heat and salt stress for 24 hours. Graphs of activity dynamics of NAD-MDH, NADP-MDG, NAD-ME and NADP-ME were constructed. Different enzymes of the malate dehydrogenase system react differently to stresses and can participate in the stress leveling. The results of the study indicate the induction of the tricarboxylic acid cycle and the intensification of the Hatch-Slake cycle under stressful conditions. Based on the data obtained, the role of the malate dehydrogenase enzyme system in the mechanisms of the adaptive mesophyll reaction of maize leaves to salinity and extreme temperatures is discussed.
