| Outline of Final Research Achievements |
In a study of flower colors and pigments in summer bedding plants (particularly, cultivars of Catharanthus, Impatiens, and Petunia), the factors of flower color expression have been confirmed by intermolecular copigmentation of flavonoids and by variation of anthocyanin concentration for flower colors. Although bluing of flower color of Petunia cultivars has been associated with a change in pressed corolla juice pH, an exception has been found. These results are considered to serve as useful basic data for future breeding of summer bedding plants with new flower colors.
