Outline of Final Research Achievements

The effects of red- and blue-light irradiation at night on abscisic acid (ABA) synthesis and anthocyanin and sugar concentrations were examined in grape vines, which were grown in two different seasons. In grapes cultivated with early heating, the ABA concentrations were highest in blue-light-emitting diode (LED)-treated skin; however, those in grapes cultivated in the ordinary growing season were highest in red-LED-treated skin. The expressions of 9-cis-epoxycarotenoid dioxygenase (VvNCED1) and ABA 8'-hydroxylase (VvCYP707A1) were high in each treatment at veraison regardless of the growing season. In both seasons, anthocyanin concentrations were highest under the blue-LED treatment, followed by the red-LED treatment. The expressions of VlMYBA1-2, VlMYBA2, and VvUFGT coincided with anthocyanin concentrations. Sugar concentrations were increased by the blue-or red-LED treatment dependent on the growing season.
