The effect of potassium deficiency on glutamate dehydrogenase(EC. 1.4.1.2) and glutamate synthase (EC. 2.6.1.53) activities in leaves of two cultivars of bean plants (Phaseolus vulgaris L.) was studied. The results showed an increase of glutamate dehydrogenase and a decrease of glutamate synthase activities in potassium deficient plants of the two cultivars studied.
