| Outline of Final Research Achievements |
Red-light irradiation increased endogenous ABA concentrations in the skin compared to those in the untreated control and blue-light irradiation in ‘Kyoho’ grape berries. However, anthocyanin and sugar concentrations in the skin were significantly increased in blue-light irradiated berries. Blue-LED cluster treatment increased sugar concentrations compared to leaf treatment. In addition, blue-LED treatment decreased the expression of ABA signal transduction retardant gene.
These results suggest that ABA signaling may be more important than ABA concentrations for anthocyanin and sugar production. Isoprothiolane retarded chlorophyll degradation in the berry skin as well as NDGA. The treatment of oxylipin increased ABA concentrations and affected synergistically against pathogen infection.
