Means ± SE. According to Fisher's test (p < 0.05), the values followed by different letters within the same plant organ and metal are significantly different, the values followed by the same letter are not significantly different, and “ab” indicates that there is no difference between values followed by a and b letters. ^∗Not detectable.
