Abstract:The research advances in organ colorations of higher plants determined by anthocyanins and its influencing factors were summarized. The coloring property, location in vacuole and non-uniform distribution in plant organs of anthocyanins contributes their colorations of organs. Molecular structures of monomeric and polymeric anthocyanins and their various changes, together with the correlation between anthocyanin synthesis and the growth and development stages of plant result in diversity of plant organ coloration. Temperature, light, water and mineral elements influence the chromas of plant organs by affecting the anthocyanin accumulation in vacuole. Vacuolar pH, oxidizing and reducing agents influence the hues of plant organs by affecting molecular structure of anthocyanins. Simultaneously, the cell shapes restrict the color changes of plant organs by influencing the optical attributes of anthocyanins, and the exploration of mechanism and artificial improvement of plant organ colorations were prospected.
