Resumen
Descripción
The assessment of the variation in juvenils needles per fascicle in Pinus caribaea var. hondurensis Barr. and Golf at 18 months under greenhouse conditions, was not significantly different between populations. Nevertheless the populations Limones and Melinda present the highest values of fascicles with four and five needles with respect to the average, and Guanaja the lowest.
It looks the genes responsible for the expresion of fascicles with four and five needles are present along the natural distribution of this variety, and that its expression is under control of climatic factors.
