HIDROBO-LUNA, Jaime R.; SANCHEZ-HINOJOSA, Verónica M.; SORIA-IDROVO, Norman A.  e  GIA-BUSTAMANTE, Jaime F.. Histological studies of the somatic embryogenesis process in Coco Cumbé Palm (Parajubea cocoides Burret), from cigotyc immatures embryos. cultrop [online]. 2017, vol.38, n.2, pp.36-44.

The aim of the present research was to determinate the type of tissue present in a sample obtained from an embryogenic callus of Coco Cumbé Palm, Parajubaea cocoides Burret and somatic embryos on globular stage. For this purpose, in order to the protocol established in the histotechnology analysis procedure manual of Patology Service from "Carlos Andrade Marín" Hospital (HCAM, according its acronyms in Spanish) was proceeded located in Quito, Pichincha, Ecuador. The results showed that the embryogenic calli are conformed by meristematic cells and although present cells with starch granules near to embryogenic cells, indicating embryos formation. In somatic embryos case, was verified that these were in globular stage, because of these showed a characteristic structure of the first development stage, named protoderm. Therefore was determined that calli present distinctive characteristics of embryogenic competence and viability of the somatic embryos
