PHENOLOGICAL STUDY OF Licania arborea Seem (CHRYSOBALANACEAE) IN JIQUIPILAS, CHIAPAS, MÉXICO

Abstract

Phenological studies allow understanding the periods of time of appearance and permanence of the life stages of a plant and their climatic relationship, with flowering and fructification being the most important, which ensure understanding the range of the phenomena with the purpose of management and propagation. The flowering and fructification events of Licania arborea were evaluated, as well as their relation with precipitation and temperature. Events were observed during the period of 2013 to 2014 on 10 trees located in the municipalities of Jiquipilas, Chiapas, México, applying Fournier’s numerical scale (1974); the climate data were obtained at the Las Flores bioclimate station (CONAGUA), and a simple regression analysis was performed, adjusting a model of Y square-inverse of X, finding that the phenological events take place once a year, where the flowering is seen from October to March, while the fructification extends from January to July. The flowering is related to the temperature (p=0.0006) (r²=0.70) and correlation coefficient of 0.84, proving that temperature plays an important role in the production of flowers.
