Studies on Bluing Effect in the Petals of Red Rose, V. : A Survey of the Various Bluing Types
YASUDA, HITOSHI

One hundred and forty five rose cultivars, including old roses, were used to determine the various bluing patterns of red rose petals. The upper epidermis of fresh petals, which had exhibited the bluing phenomenon, were peeled and examined microscopically. The bluing patterns observed were grouped into three types. The first was the cell sap-type where the central vacuole of upper epidermal cells was uniformly blue without any apparent blue structures. The second was a tannin body-type in which blue spherical tannin bodies appeared in the vacuoles. The third was a miscellaneous-type which included blue structures in the vacuole other than tannin bodies. Old roses drived from Rosa chinensis usually exhibited the cell sap-type of bluing while those derived from Rosa gallica had a tendency to exhibit a combination of the tannin body-miscellaneous bluing types. Combinations of two or even all three of the bluing types were found in some cultivars. With the long history of rose breeding, the various bluing types and their combination could have evolved through the segregation and recombination of the bluing factors, specifically when Rosa chinensis or Rosa gallica were used as parents.
