Figure 1

Effect of metal treatments on root growth in Camelina and rapeseed. Seeds were germinated and grown on agar plates containing 50 μM Cd, 500 μM Pb, 500 μM Zn, and 100 μM Co for seven days. Data represent means ± SD (n = 30). Mean values of root length in the normal medium as control for Cd, Zn, and Co were 4.10 ± 0.69 (Camelina) and 4.62 ± 0.53 (rapeseed); mean values of root length in the no-phosphate medium control for Pb were 3.25 ± 0.11 (Camelina) and 3.80 ± 0.55 (rapeseed). Asterisks in the figure indicate significant difference between Camelina and rapeseed subjected to the same treatment at ***P < 0.001 by Student’s t-test.
