| Outline of Final Research Achievements |
Quality maintenance of horticultural produce after stress treatments and its evaluation using molecular markers were determined. We investigated anthocyanin biosynthesis and keeping quality of blueberry fruit after heat treatment, gene expression of enzymes related to the production and elimination of hydrogen peroxide in broccoli florets, control of tomato fruit ripening and effect on ethylene production-relating genes by ethanol treatment, and activation of the antioxidative system by hydrogen peroxide treatment and its relation to quality maintenance in sweet pepper fruit. The possibility of quality evaluation using molecular markers was suggested by clarifying the relevance between quality changes of heat-treated broccoli florets and expression changes of freshness marker genes. Cooperative research on keeping quality of Thai lime fruit by stress treatments was also conducted with Thai research collaborators.
