Phytotoxicity of Pb: I Effect of Pb on Germination, Growth, Morphology and Histomorphology of Phaseolus mungo and Lens culinaris

Rafia Azmat, Saba Haider and Shabana Askari

Abstract:
This study examined the effect of toxic metal Pb on Phaseolus mungo and Lens culinaris. Results showed that Pb markedly affect the Lens culinaris as compared to Phaseolus mungo. A pronounced effect of Pb on plant roots of both species shows the rapid respond to absorbed Pb, through a reduction in rate of seed germination, morphology with change in branching pattern. Histomorphological changes in root and vascular tissues in both species may be related with the conduction of water in the plant followed by inhibitory effect on germination of seeds and retarded the growth of seedlings. Pb also decreases the germination percent, germination index, root/shoot length which also depend upon the nature of plant species.
