Abstract:

Plants exhibit various responses to environmental stresses. A laboratory experiment was conducted to determine the influence of heavy metals(Cd, Cr) and water stress induced by polyethylene glycol(PEG) on germination and early seedling growth of two black gram (Vigna mungoL.Hepper) cultivars. Seeds of two black gram (Vigna mungo L.Hepper) cv. LBG-623 and LBG-752 cultivars were subjected to water stress by using PEG – 6000 (-0.3MPa, -0.6MPa,-0.9MPa and -1.2MPa) heavy metal stress by Cadmium and Chromium(20,60,100,200,400ppm). Results indicated that a significant inhibitory effect was observed at all levels of single and combination of stresses.
