Figure 15. Leaves showing mineral nutrient deficiency symptoms (A-D) and greening disease symptoms (E). Nutrient deficiencies are manganese (A), iron (B), zinc (C), and magnesium (D). Note the uniformity (symmetry) of the mineral deficiencies; the left and right halves of the leaves are mirror images of one another. The greening leaf (E) does not show this symmetry.
