Caracterización morfológica y evaluación de la germinación de semillas de dos especies tintóreas de la provincia de Zamora Chinchipe

Abstract

Kumphia (Renealmia alpinia) and Sua (Genipa americana), are two native dying species of Zamora Chinchipe Province, which have little information about their morphological, physiological and reproductive characteristics. This study was carried out in the UTPL Germplasm Lab, whose objective was to evaluate the morphology of their fruits and seeds; an individual was studied in G. americana because it was the only specie found in this area and five individuals were studied in R. alpinia, considering aspects such as size, shape, weight, moisture content, according to the ISTA 2007 standards and also the germination capacity was evaluated by separating the small from large seeds. The fruits and seeds of R. alpinia presented little morphological variation both among individuals and among provenances; while its germination was greater in the seeds coming from the Kimm, however in both provenances high germination was observed in the large seeds. In G. americana were found variations in the size of the fruits and seeds, presenting greater germination in the large seeds.
