This review has focused predominantly on the function of manganese in plants and its concentrations
for maintaining optimal growth; the vast literature on diagnostics is heavily drawn on in Table 12.1.
Developments in the last 10 years in manganese physiology and diagnostics have largely been
refinements on the previous work rather than new radical developments. This may change with the
emerging of new molecular technologies in the area of plant mineral nutrition.
