| Outline of Final Research Achievements |
Plant species for urban greening are limited because of severe growth condition. There are abundant unutilized genetic resources of Hydrangea macrophylla in Japan. In this study, we explored novel hydrangea germplasm with tolerance to the excessive solar radiation from Izu Islands in order to develop suitable hydrangea cultivars to urban greening. Some wild plants introduced from Izu Islands including Hachijojima Island and Niijima Island showed remarkable tolerance to the excessive solar radiation in screening tests. We found wild Hydrangea macrophylla plants growing under severe environmental stress including excessive solar radiation, oligotrophic soil and desiccation in seven areas in Miyakejima Island.
