Abstract

Foliar application of lead applied in four differentconcentrations (1,4,7 and 10mM) and the control (0) at five
growth stages (28, 35, 42, 49 and 56 DAS) of rnungbean resulted in increased activities of both peroxidase and IAA
oxidase. Highest stimulation in peroxidase activity was recorded at 56 days after sowing (DAS) by 10 mM dose
while IAA oxidase showed maximum activity at 35 DAS under same dose. Lead also caused growth inhibition of
plants by decreasing plant height, dry weight of leaf, stem and five entire plants.The effect was pronounced towards
higher concentrations of lead.
