Systematic Review of the State of Knowledge About Açaí-Do-Amazonas ( Mart., Arecaceae).

Mart. is an increasingly important palm for subsistence and income generation in central and western Amazonia with growing demand for its fruit pulp, which is an alternative source of açaí juice for domestic and international markets. This study synthesizes current knowledge on its systematics, ecology, fruit production in natural populations, fruit quality, uses, population management, and related areas, identifying critical research gaps. A systematic literature survey was conducted across databases including Web of Science, Scopus, Scielo, CAPES, and Embrapa. Of 1568 studies referencing , 273 focused on , with 90 addressing priority themes. Genetic diversity studies suggest the may represent a complex of species. Its population abundance varies across habitats: the highest variability occurs in , followed by and . exhibit greater productivity potential, with more bunches per plant and higher fruit weight than ; no production data exist for . Additionally, has higher anthocyanin content than , the primary commercial açaí species. Management of natural populations and cultivation practices are essential for sustainable production; however, studies in these fields are still limited. The information is crucial to inform strategies aiming to promote the sustainable production of the species.
