title: Influence of cadmium on growth and development of Vicia faba Linn.
abstract: Influence of cadmium (Cd) on growth and development of broad bean (V. faba) was assessed in pot cultures with cadmium iodide (CdI2) in different concentrations ranging from 15 to 500 mg per kg of soil. There was a decline in plant height and total dry weight. Root size decreased most significantly with a corresponding reduction in the frequency of root nodules. Total soluble protein in leaf, stem and root suffered a pronounced loss with increasing concentration of cadmium. Chlorophyll a was the most sensitive pigment followed by chlorophyll b and carotenoids. Nitrate reductase activity too was adversely affected. Cadmium contamination induced abnormalities in stomata and trichomes.
