Cadmium-treated pea plants exhibited PEPC and NADP-ME activities, titratable acidity, and malate concentration in the leaves similar to controls. The PEPC activity in the roots of Cd-treated plants decreased by about 40 %, and NADP-ME increased more than twice. The titratable acidity remained similar as in the leaves, but the malate content diminished by about 30 %. The application of 500 g(d.m.) m** (-3) biomin and a combination of biomin and algae suspensions to Cd-treated plants brought about an increase in the titratable acidity and in the malate concentrations in the leaves and the roots.
