Conclusion

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.
