 note = {Flowers from detached buds of three lisianthus cultivars, 'Asuka no Asa', 'Mickey Rose' and 'Asuka no Kurenai', were examined in vitro to investigate the influence of the partial UV-A (380-400nm) and blue light (400-470 nm) spectra of visible light on petal coloration and flavonoid accumulation. The saturation and hue of flower color changed with time after anthesis under conditions of darkness, control irradiation (380-700 nm) and 380-470 nm cut irradiation (470-700 nm). The chromaticity of lisianthus flowers was highest in the control, but the hue angles of flower petal color did not differ among the three conditions in any of the cultivars. Anthocyanin biosynthesis was enhanced by partial UV-A and blue light as well as 470-700 nm of visible light, whereas flavonol biosynthesis did not proceed without partial UV-A and blue light. Although the biosynthesis of pigments might start before flower opening and partial UV-A and blue light spectra were considered to be a factor for accelerating the synthesis after anthesis, minimum petal flavonoids aggregated even in darkness where the quantity retained a similar level to that found before treatment. The wavelengths 380-470 nm are required for the expression of vivid flower colors as well as for the accumulation of flavonoids without changing lisianthus flower hue.},
