Relationship between morphology and dispersion of Juglansjamaicensis DC with the distance to the water course

Abstract

The study was conducted in the Turquino National Park in the Zonal Conservation Units Santo Domingo and La Platica, to establish the relationship between the shape of the seeds of Juglansjamaicensis and distance to waterways as an adaptive response to their dispersal mechanism 7 groups of trees were selected. Each player is taken tree seeds 50 which were performed measurements of height (H), width (L) and thickness (E) to determine the rate of roundness (R). The distance of each tree nearest the course of water was also measured. The relationship between the two variables was performed through a simple correlation analysis; however the comparison of means was through a simple ANOVA, while the distribution of the shape of the seeds in relation to the distance to the watercourse was analyzed through the Tukey test. Those trees closer to water courses had more round seeds, indicating that the mechanism of scattering by water influences the environment in which they live. The roundness index varied and seeds were identified with rates ranging from medium to high (0, 81 to 1, 12; mean = 1, 01). These results suggest that the shape of the seeds is an adaptation of trees J. jamaicensis the medium in response to dispersal mechanism for water.
