In this paper we focus on anatomic structure of the outer cellular layers of the fruit of Sorbus torminalis. We have confirmed the theory of existing of multilayered epidermis providing developmental, histogenetic evidence. The studies were made from blooming time (ovules) to fully ripen fruits, using various histological techniques and microscope types. The multilayered epidermis is derived from successive tangential divisions of cells of initially single-layered epidermis commencing about two weeks after full bloom. The subsequent epidermal layers result from division of cells of epidermal meristem. The mature fruits – about 12 weeks after full bloom – are covered with four – to five-layered epidermis; each layer with its own cuticle. The lenticels developed beneath stomata from phellogen which is not in continuity with the epidermal meristem. Measurements of cuticular membranes thicknesses during development were also made.
