Plants are sessile and sensitive organisms that inevitably encounter a variety of abiotic stresses in nature. Abiotic stresses such as salinity, drought, heavy metal toxicity and extreme temperatures are critical factors that reduce crop yields by more than 50% worldwide. Sustainable agriculture in harsh environments requires an understanding of the ways that crop plants respond to both biotic and abiotic factors. The aim of the study was to determine the influence of water stress and heavy metals (Cd and Cr) singly and in combination on germination and seedling growth of two Green gram (VignaradiataL.Wilzec) cultivars.Seeds of two Green gram (Vignaradiata L. Wilczek ) cv. ML – 267, TM 96-2 cultivars were subjected to water stress by using PEG – 6000 ( -0.3 MPa , -0.6 MPa , -0.9 MPa and -1.2 MPa); Cadmium and Chromium(20,60,100,200,400ppm). The seed germination percentage decreased significantly with increasing concentration of Cd and Cr. Decreased osmotic potential caused a decrease in germination percentage. In comparison with the control treatment, the lowest germination rate values determined at -0.9MPa, 400 ppm Cd and 400 ppm Cr. Shoot and root length was reduced significantly with a rise in PEG and heavy metal levels. Cd concentration had a more depressing effect on the root than on the shoot growth. Interactive effects between heavy metal and water stress on dry weight and root length was significant. According to this study the interactive effect of both stresses were however, less than additive. References Almansouri, M., Kinet, J.M., Lutts, S. 2001.
