| Outline of Final Research Achievements |
The function of boron in plants is nowadays well established to be the stabilization of cell walls by borate cross-linking of wall pectin. We attempted to develop a diagnostic method for boron deficiency in plants using the borate cross-linking ratio of pectin as an index. Recently, blackening disorder of broad bean pods caused by boron deficiency was observed in farmers’ fields in Kagoshima prefecture, Japan. We used the affected broad bean plants as samples to demonstrate the usefulness of the method of diagnosis for boron deficiency occurred in fields. Then we applied the diagnostic method to several crops on which boron deficiency was suspected from the symptom, and finally proposed diagnostic criteria for boron deficiency.
