Colección y caracterización morfológica de semillas y embriones de especies distribuidas en la provincia del Guayas

Abstract

The study aimed to provide information on the morphological characterization of seeds of 10 plant species belonging to six families of a dry tropical forest in the province of Guayas. The seed length had a mean of 13.34 ± 5.8 mm and the mean width was 6.84 ± 3.05 mm. The mass presented a mean of 1.08 g ± 1.84 and the volume varied from 19.21 mm3 to 1288.08 mm3. Most of the species were characterized by having ovoid seeds and endosperm in 9 out of 10. The texture showed as a tendency seeds with hard and semi-hard brows in 70% of the cases and the color of the forehead predominated the tones Dark The predominant form of the embryos was the linear one in 40% of the species and the one in the 30%. In the cotyledons elliptical forms predominated and clear coloration. The seed grouping was carried out in two sets: those seeds with lengths greater than 15 mm and with a length below this measure.
