REPRODUCTIVE PHENOLOGY OF THE USPÍ TREE Couepia polyandra (Kunth) Rose (CHRYSOBALANACEAE) IN THE MUNICIPALITY OF PALIZADA, CAMPECHE, MEXICO

Abstract

Objective. The different reproductive phenological phases are described from the formation of flower buds, flowering, fruiting to the formation of the mature fruit and foliation of 21 Couepia polyandra trees and the correlation of the allometric data of the height of the tree, the diameter to the height of the chest (DAP) and crown diameter, as well as the correlation of precipitation with reproductive phenology data.

Methodology. The description of the reproductive phenology (foliage, formation of flower buds, flowers, fruits) was made by monthly direct observation with the help of a photographic camera (Canon SX60HS, 65), the correlation between precipitation, allometry and types of soils where trees grow by recording data for each tree and measurements of height, diameter at chest height (dbh) and foliage were taken.

Results. The tallest tree was found to be 21.0 m; the highest dap found was 68 cm and the diameter of the main crown was 34.45 m. with general averages of 10.38 m, 33.17 cm and 9.37 m respectively. A significant correlation was found between Height and DBH (r = 0.91, p <0.05), the correlations for the Height-Cup and DBH-Cup variables were not significant (p> 0.05).

Conclusions. The presence of the water factor is responsible for the formation of inflorescence and fruit, pointing out that these events, as well as their relationship with precipitation, are dependent variables, where it presented a positive average relationship with the production of flowers on the tree.
