Comparison of ATPase activity in leaves of two barley genotypes. H+-ATPase (A), Na+K+-ATPase (B), Ca2+Mg2+-ATPase (C), and total ATPase (D) of Weisuobuzhi and Dong17 were measured in the control and after 15 d of 5 μM Cd treatment. Data are means ± SD (n = 4). The value of total-ATPase activity is not the sum of all ATPase activities due to different methods used in the assay. Different lowercase letters in each graph indicate significant differences at P < 0.05.
