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

Abstract

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.
