Factors affecting flower colour


, : Factors affecting flower colour. Acta Horticulturae (41): 57-68

Anthocyanins and other flavonoid components were isolated from a range of flowers including bulbous iris, azalea, rose and pelargonium. Spectral absorption curves of entire fresh flower petals or intact epidermal cells were obtained using a microspectrophorometer. Methylation and hydroxylation were the main factors influencing the colour of anthocyanins, methylation reducing blueness and hydroxylation enhancing it.

Quantitative effects of major pigments on flower colour variation, and measurement of colour qualities of petals with a colour difference meter. Sixty-eight cvs were placed in 4 colour categories: white, pink-to-reddish-purple, yellow, and orange-to-red. TLC revealed 3 major anthocyanin spots in 49 cvs and 10 major carotenoid spots in 26. Carotenoids were responsible for colour expression...
