Abstract
In the current research work, the effects of different concentrations of Manganese and Iron on various growth parameters of Phaseolus lunatus L. were studied. For this purpose pots experiments were performed in three replicates. Three concentrations each of Manganese and Iron (2millimolar (mM), 10mM and 20mM) were used as metal stress treatments. A single series of 3 pots with no treatment was designated as the control. The results showed that number of days to germination were more in treated plants as compared to control. Hence, seed germination was negatively affected by the applied metal stresses. Similarly number of seeds germinated per treatment was also decreased with the increasing concentrations of the treatments. All the other growth parameters including plant height, number of leaves, shoot length and root length significantly reduced with the increase in concentration as compared to control. While fresh and dry weights increased at the lower (2mM) concentration while decreased significantly with the higher (10mM and 20mM) concentrations.
