Figures & data

Figure 1. Effect of SA (10−5 M) on the Cd (0, 25, 50, or 100 mg per kg of soil) induced changes in nodule number (a), nodule fresh mass (b), nodule dry mass (c), nodule leghemoglobin content (d), nodule nitrogenase activity (e), and root nitrate content (f) in Cicer arietinum at 90 DAS. Data are the mean of three independent replicates. Vertical bars represent standard error (±).
