Advances in the propagation of acerola

Abstract The acerola tree (Malpighia emarginata Sessé &Moc. ex DC.) is a fruit species that has prospered in the Brazilian tropical regions, especially in the Northeast, thanks to the high content of vitamin C in the fruits, among other characteristics that make it attractive to the producer, such as early production. Although there is increasing demand for the product, the production of certified seedlings of good commercial varieties is still a barrier to further expansion of the crop. This review aims to present, in a comprehensive way, technical information on how the spread has been made since its introduction in the country, as well as innovations and advances. Traditionally, propagation is carried out through seeds, cuttings and by grafting on top of common acerola rootstocks, with no defined origin. The advances presented are focused on the use of new canopy and rootstock varieties, including the use of double grafting, minicutting and tissue culture, with studies still in progress, and use of new substrates such as coconut fiber.
