EFFECT OF METAL STRESS OF IRON, COPPER AND ZINC ON AMYLASE, ACID PHOSPHATASE AND ALKALINE PHOSPHATASE ACTIVITY IN Phaseolus vulgaris Authors: Kaur A , MITTAL N, KAUR A
ABSTRACT
Acid and alkaline phosphatases in plants play a major role in the supply and metabolism of
inorganic phosphate for the maintenance of cellular metabolism. Phosphate plays an
extremely important role in a variety of reactions in germinating seed including energy
metabolism and synthesis of nucleic acids and membranes. In the present study, the effect of
different concentrations of iron, copper and zinc (50mM, 100mM, 150mM, 200mM) on
hydrolysis enzymes activity e.g., amylase, acid and alkaline phosphatase was studied in
Phaseolus vulgaris. In the present study, with the increasing concentration of iron (Fe), zinc
(Zn) and copper (Cu) toxicity there was decrease in phosphate levels. There was significant
decrease in acid and alkaline phosphatase levels in seeds of Phaseolus vulgaris treated with
Zn and Cu heavy metal with increasing metal concentration (p?0.05). No significant change
on acid phosphatase activity was observed with Fe metal toxicity.
