Accumulation and distribution of heavy metal cadmium in sweet sorghum

In this study, two varieties of sweet sorghum (Keller and ETian) were grown with 5 levels (0, 5, 10, 25 and 50 ppm) of cadmium (Cd) in order to investigate the accumulation of Cd in plant parts at the hard dough stage. The results clearly showed the absence of Cd in the seeds of the above plants. | Nong Lam University Ho Chi Minh City 57 Accumulation and distribution of heavy metal cadmium in sweet sorghum Tra T. T. Dinh Department of Environment and Biology Quang Binh University Quang Binh Vietnam ARTICLE INFO ABSTRACT Research Paper Many species of plants have been studied as well as applied for cleansing the environment. Previous research has concluded that Received October 01 2019 sorghum plants are highly tolerant to metal pollution and capable of Revised November 29 2019 reaching high biomass values in the presence of metals. However the Accepted December 09 2019 distribution of heavy metals in plant s parts has not been adequately studied. In this study two varieties of sweet sorghum Keller and E- Tian were grown with 5 levels 0 5 10 25 and 50 ppm of cadmium Keywords Cd in order to investigate the accumulation of Cd in plant parts at the hard dough stage. The results clearly showed the absence of Cd in the seeds of the above plants. There was the presence of Accumulation Cd at the second and fifth leaf when the level of Cd reached 25 - Cadmium 50 ppm. There was a great correlation coefficient between Cd and Distribution the position of the internodes namely 0.86 0.96 0.99 0.98 with Hard dough stage KE and 0.86 0.92 0.94 0.94 with ET at 5 10 25 and 50 ppm Cd Sweet sorghum P lt 0.01 respectively. The greater the internodes the lower the accumulation of Cd. The aforementioned plants recorded the high accumulation of Cd in their roots peaking at 23.27 µg g dried Corresponding author weight dw in Keller and 21.69 µg g in E-Tian. Based on these results it is concluded that the distribution of Cd in the studied Dinh Thi Thanh Tra sweet sorghum can be arranged in the following order gt stem gt Email dinhthanhtra83@gmail.com old leaves gt young leaves.
