ABSTRACT

 

Heavy metals are the compound which are naturally occurring elements that have a high atomic weight and density. Cadmium is a carcinogenic element.The main sources of cadmium getting to environment includes burning of diesel and heating oil, agricultural practices like use of phosphate fertilizers, sewage sludge, car tyres, street dust, smelting industries thereby entering to agricultural soils and water bodies by its sources. The present study deals with observing parameters like Percent germination, % phytotoxicity of root, % phytotoxicity of shoot, Seedling vigour, Tolerance indices, seedling weight, fresh biomass and dry biomass on growth of Vigna mungo L. by subjecting the seeds to different concentration of Cd2+ ranging from 1 ppm to 10 ppm. The result showed that there was no negative effect on seedling growth with lower concentration but at higher concentration the seedlings were not tolerant and the vigour index also showed the same pattern.

 

Keywords : Cd2+, Seed germination, Seedling growth, Phyto-toxic, Vigna mungo L.
