Comportamiento fenológico de Wercklea insignis (Malvaceae) en un Bosque Pluvial Premontano, San Ramón, Costa Rica

Abstract

I studied the phenology of W. insignis (n =10), tree with great ornamental potential with conspicuous flowers, which grows on the San Lorencito riverbed, in the Alberto Manuel Brenes Biological Reserve, Alajuela, Costa Rica, June 2014 until October 2015. Of the selected sample of six individuals with flower production, the diameter at breast height ranged from 7 cm to 11.9 cm, while the highest trees measured 15 m. The identification of the individuals was done with plastic marks enumerated, after this they were georeferenced. In relation the flowering phenotypes (subanual), foliar sprouts, fall foliage were continuous, without having a total loss of the leaves. While the fructification was absent in October 2014 and June 2015. There was asynchrony between individuals in the behavior of the phenological stages. The fall of foliage (n = 10, r = 0.35, p <0.05) and flowering (n = 10, r = 0.46, p <0.05) correlated with precipitation while fruiting (n = 10), r = -0.51, p <0.05) had an inversely proportional correlation with this phenomenon.
