Figure 2

Metal contents in roots and shoots of Camelina and rapeseed .Four-week-old plants were grown hydroponically and treated with 50 μM Cd, 500 μM Pb, 500 μM Zn, and 100 μM Co for one week. Data represent means ± SD (n = 3) from three independent plants. Asterisks in the figure indicate significant difference between Camelina and rapeseed subjected to the same treatment at *P < 0.05, **P < 0.01, and ***P < 0.001 by Student’s t-test.
