Germination, Seedling Growth and Biochemical Responses of Amaranthus (Amaranthus tricolour L.) and Sesame (Sesamum indicum L.) at Varying Chromium Concentrations
Journal Title: International Journal of Plant & Soil Science - Year 2017, Vol 20, Issue 5
Abstract
The main objective of present investigation was to evaluate the impact of different concentrations of hexavalent chromium on germination and seedling growth responses of Amaranthus (Amaranthus tricolor L.) and Sesame (Sesamum indicum L.). Every treatment was replicated thrice in a randomized block design. Observations were made on germination rate, root and shoot length, fresh weight and dry weight of seedling, % phytotoxicity of root and shoot, sugar, and chlorophyll content in the leaves of both treated and control plants. Steady increase in Cr (VI) fixation under different concentration under various treatments significantly leads to inhibition of seed germination and other development parameters. Percentage of phytotoxicity demonstrated an increasing pattern with continuous increment in Cr VI concentrations for the entire Amaranthus tricolor L. and Sesame (Sesamum indicum L.) cultivars. Most extreme restraints of root development were recorded. Endeavors are being made in various research centers to build novel plants utilizing hereditary control innovations that may have a more noteworthy resistance o the nearness of heavy metals. The consequence of the present investigation may help in understanding the components included and their conceivable use in phytoremediation. The germination and seedling growth responses of Amaranthus (Amaranthus tricolor L.) and Sesame (Sesamum indicum L.) were assessed in varying concentrations of K2Cr2O7. Germination of both green Amaranthus and Sesame was significantly affected by the increasing K2Cr2O7 concentrations. Root length and shoot length of both the green Amaranthus and Sesame were inhibited by the high K2Cr2O7 concentrations as compared to those containing low K2Cr2O7 concentrations and control treatment.
