Abstract
Las observaciones fueron realizadas en la
Estación Experimental Fabio Baudrit, Alajuela.
Se aplicaron diversas prácticas de manejo químico y cultural en el período del 2008 al 2012,
sobre árboles de lichi propagados por acodo,
con el objetivo de observar su influencia sobre
la floración. Las prácticas de manejo y productos
utilizados fueron: el riego con restricción,
raleo de ramas, aplicación de nitrato de potasio,
paclobutrazol y ethrel. Ninguna de las prácticas
utilizadas influenció positivamente la floración
de los árboles bajo observación; por el contrario,
fundamentalmente los tratamientos utilizados
promovieron el crecimiento vegetativo. Se teoriza
que se requieren períodos más prolongados
de temperaturas por debajo de los 20ºC para que
los árboles tengan mayores posibilidades de ser
inducidos a florear.
Observations were made in the Fabio Baudrit Experiment Station. Several chemical and cultural management practices were applied, over the course of several years (2008-2012), on young lychee trees that had been propagated by means of air layering, with the purpose of observing their influence on blooming. The practices and products tested were: irrigation restriction, branch thinning, potassium nitrate, pachlobutrazole and ethrel. None of the management practices applied had a positive effect on the flowering of the trees under observation. It is speculated that lychee trees require prolonged periods with temperatures under 20ºC, for flower induction to occur.
