Vegetative propagation of camu-camu by intergeneric grafting in Myrtaceae family

Abstract

Camu-camu [Myrciaria dubia (Humb., Bonpl. & Kunth) McVaugh], of the Myrtaceae family, can be found at flooded areas in the Amazon region and it is used like a conservant in antioxidants due to its high ascorbic acid content. In order to obtain rootstocks of this family adapted to dry land for vegetative propagation of camu-camu, two hundred and forty plants of camu-camu, guava (Psidium guajava L.) and Surinam cherry (Eugenia uniflora L.) were selected. They received four different kinds of grafting, originating twelve treatments of sixty plants and five repetitions. Only the camu-camu rootstocks showed compatibility. Incompatibility between camu-camu and the rootstocks of guava and Surinam cherry was demonstrated by anatomical analysis.
