Physiological and Anatomical Investigation of Flower Colors of Primula vulgaris L.

ABSTRACT

Primula vulgaris L. (Primrose) of Primulaceae family is an annual or perennial herbaceous ornamental plant with white, yellow, pink, red or violet flowers. There is no study on the relationship between various pigments and petal colors of this plant, which has an important place in urban architecture, is resistant to cold weather, and grows in scattered clumps, and the leaves and flowers of which are clustered in the form of a rosette at the base. This study aims to inspect the relationship between anthocyanin, which colors the flowers of P. vulgaris employed as material in this study and chlorophyll. It further aims at determining whether there is a relationship between the active ingredients of Primula as a publicly favored medicinal plant and its total protein content. Consequently, it has been physiologically and anatomically proved that anthocyanin existed more at the root, at the basal part of the spatulate leaf, and at the base of the long flower stalk, and was synthesized more in the abaxial and adaxial epidermal cells in the flower petal.
