Optimization of an in vitro culture protocol of Coyol embryos (Acrocomia aculeata)

Abstract

El coyol (Acrocomia aculeata), es una palma distribuida principalmente en la Región del Pacífico de Costa Rica, su principal uso ha sido la obtención de una bebida conocida como vino de coyol y los frutos como alimento para el ganado. Además, es una especie que tiene un gran potencial, debido a que de los frutos y semillas se puede obtener aceite que puede ser utilizado para producir biodiesel, alimentos y cosméticos, entre otros. Son pocas las plantaciones comerciales que existen en el mundo, sin embargo, Brasil es uno de los países que está apostando a la siembra de esta especie en mayores extensiones. Uno de los problemas que se tiene al trabajar con esta especie es la alta dormancia de sus semillas y los bajos porcentajes de germinación. Por tal motivo el objetivo del trabajo fue el establecimiento y estandarización de un protocolo de germinación in vitro de embriones de coyol (A. aculeata). Se colectaron frutos de plantas de coyol (A.aculeata) ubicadas en diferentes sitios de las provincias de Guanacaste, Alajuela, San José y Puntarenas de Costa Rica, durante el año 2018. Se separó el exocarpo y mesocarpo y se desinfectó el endocarpo, posteriormente se extrajeron los embriones y se sembraron en diferentes medios de cultivo in vitro. Se logró obtener un protocolo de desinfección y de germinación.

Coyol (Acrocomia aculeata), is a palm distributed mainly in the Pacific Region of Costa Rica, its main use has been to obtain a drink known as coyol wine and the fruits as feed for livestock. In addition, it is a species that has great potential, because of the fruits and seeds you can obtain oil that can be used to produce biodiesel, food and cosmetics, among others. There are few commercial plantations that exist in the world, however Brazil is one of the countries that is betting on planting this species in larger areas. One of the problems we have when working with this species is the high dormancy of its seeds and the low percentages of germination. For this reason, the objective of the work was the establishment and standardization of an in vitro germination protocol of coyol embryos (A. aculeata). Fruits were collected from coyol plants (A. acuelata) located in different sites in the provinces of Guanacaste, Alajuela, San José and Puntarenas of Costa Rica, during 2018. The exocarp and mesocarp were separated and the endocarp was disinfected, subsequently embryos were extracted and seeded in different in vitro culture media. A disinfection and germination protocol was obtained.
