MORPHOLOGIC AND MOLECULAR CHARACTERIZATION OF SPECIES OF Myrciaria spp

Abstract

The jabuticaba tree is considered one of the most tipical brasilian fruit tree, however, there are a little of studies of this plant in the literature and even in the specilized literature, there are controversies about its classification many. The present work makes some comparisons between jabuticaba species, using morphologic markers (organography) and molecular markers (RAPD) technique. The morphologic characteristics of the plants, used as morphologic markers, were compared with specimens present on herbaria from São Paulo and Minas Gerais states and through the revision of specialized literature. Molecular differences between the species were identified by molecular in Piracicaba, Jaboticabal and Ituverava cities, São Paulo, Brasil. Morphologic and molecular differences between the studied plants were identified and arranged in four groups, the identified species were: Myrciaria cauliflora (Mart.) O. Berg, Myrciaria coronata Mattos, Myrciaria jaboticaba (Vell.) O. Berg., Myrciaria phytrantha (Kiaersk.) Mattos. The technique of molecular markers with the technique of morphologic markers (organography) showed to be an important tool in the identification of jabuticaba tree species.
