Effect of Inhibitors and Activators of Phosphofructokinase on the Oxygen Uptake in Plants under Salinity Conditions

Abstract

The effect of inhibitors and activators of phosphofructokinase on the absorption of oxygen by the roots of wheat seedlings was studied under normal and salinity conditions. It was revealed that in the control version the absorption of О₂ by seedling roots was significantly increased and the effect of acceptor ADP was appeared after introduction of 10^-3М АМР and 4·10^-4М of inorganic phosphate into the system. However, under salinity conditions the acceptor effect of ADP did not occur, and the absorption of oxygen was somewhat reduced.
