SALT-STRESS INDUCED CHANGES OF THE ACTIVITY OF H^+-PUMPS IN ROOT CELLS AND CO_2-METABOLISM ENZYMES IN LEAVES OF WHEAT GENOTYPES

Abstract

In the present study some local wheat genotypes, including Barakatli 95, Garagylchyg 2 and Gyrmyzy bugda have been divided into 6 biogroups according to the morphological structure of seed embryos and the effects of high NaCl concentrations on the H⁺-pums function and the activities of carbon metabolism enzymes have been determined. It was found that under salt stress CA, RBPC, NAD-MDH enzymes in the leaves and H⁺-pumps of the root system act in a coordinated manner in various biogroups and thereby play an important role in the formation of salt tolerance mechanisms.
