| Research Abstract |
Blue light promotes NADH-specific nitrate reductase (NADH-NR) activity in the leaves of the spinach plants more than red light. This promotion might be caused by the increase of the nitrate content in the xylem sap. The release of nitrate from the vacuole might not relate to the promotion of NADH-NR activity. These mean that nitrate stored in the vacuole of spinach leaves was not depleted. Therefore, it was difficult to control the nitrate content of the spinach leaves by blue light irradiation.
