Abstract

Spectrophotometric studies were made on fresh flower petals of 139 species and/or cultivars in forty families on the basis of their absorption peaks in the visible light wavelength region. The absorption spectra measured were classified into mainly four flower groups according to the types of aglycones (anthocyanidins) and their absorption spectral patterns. The relationships between flower colors, absorption spectra and structures of anthocyanins were investigated for the above mentioned four flower groups. These investigations may give a clue to the chemical basis of color variation in the flowers.
