An experiment was carried out to assess the single and combined effects of cadmium (Cd) and zinc (Zn) on growth and component wise biomass accumulation in carrot (Daucus carota L.) plants, grown under natural field conditions. Carrot plants were raised in field and treated with 10 and 100 μ g mL- 1 of Cd, 100 and 300 μ g mL- 1 of Zn singly, and in combination through soil drench. A control was also kept without any treatments of Cd and Zn. The impacts of different treatments of Cd and Zn on carrots were evaluated in terms of number of leaves, leaf area, plant length, and component wise biomass accumulation at different plant ages. Growth indices were also calculated to assess the biomass allocation patterns in carrots. The results showed that the above parameters were significantly affected in carrots treated with Cd and Zn singly and in combination as compared to the control as well as plants treated with 100 μ g mL- 1 of Zn. The results also showed that treatments of Cd and Zn have significant effects on biomass allocation pattern. This study concludes that growth and biomass accumulation in carrots were significantly influenced by the concentration ratios of Cd and Zn in soil/root/stem/ leaves. It is clear from this study that combined treatments of Cd and Zn have more negative impacts on above parameters as compared to their individual treatments. |
