Abstract

Açaí (Euterpe oleracea) is a palm tree found in abundance in the Amazon and, mainly, in Pará. It has great economic importance, making the Amazon, combined with Euterpe precatoria, the largest supplier of açaí for national and international markets. Due to this high demand for the fruit of the açaí, the management aiming at the enrichment of the species and its high capacity of regeneration, homogeneous forests of this palm tree are appearing, damaging the biodiversity of the Amazon biome. Studying the regeneration of E. oleracea will be important to establish sustainable strategies for the management and ensure the maintenance of genetic diversity of the species over time, as well as studying the crossing system may help in determining the genetic structure of the E. oleracea Thus, in this project will be studied the genetic diversity of regenerants using SNPs markers through the sequencing genotyping method, in order to obtain greater coverage of the genome and analyzed the mating system of this species using microsatellite markers, because these markers have a bad discrimination in determining the alleles in the genotypes.
