Variación interespecífica morfológica y germinativa de la especie Cedrela odorata L (Meliaceae). Estudio realizado en el sector Daucay, cantón Atahualpa en el año lectivo 2018-2019.

Abstract

Abstract: The study was conducted in the sector Daucay, canton Atahualpa, province of El Oro- Ecuador with the objective of knowing the patterns of interspecific morphological and germinative variation of Cedrela odorata L., collecting 20 fruits from each of the 10 individuals, they were weighed and photographed to measure the length and width. The seeds of each fruit were extracted and counted, and measured with the imageJ program. To evaluate germination, 50 seeds were selected per individual and planted in plastic containers with absorbent paper. At the end of the trial, the cut test was carried out, accounting for viable and non-viable seeds. According to the results of the measurements, it could be seen that there were differences in the dimensions, weight and seed production of the fruits, and the dimensions of the seeds, which is detailed in the work. It was also determined that the seeds showed a high viability index. Knowing morphophysiological aspects in the seeds of tropical species is the first step for management, conservation and use of forest species.
