Abstract

CAMCORE has visited 33 populations of Pinus caribaea var. hondurensis in Belize, Guatemala, Honduras, El Salvador, Nicaragua, and Quintana Roo, Mexico. Seed collections have been made in 29 provenances from 1,325 mother trees. A total of 21 provenances and sources of Pinus caribaea var. hondurensis were tested in 48 provenance/progeny trials in Brazil, South Africa, and Venezuela. Growth rates in Brazil and Venezuela were quite promising, and were less encouraging in Colombia. In Brazil and Venezuela, heights were around 12m and mean DBH was around 18 cm at age 8. Growth in Colombia was substantially slower, with mean height less than 8 m at age 8, and mean DBH around 13 em, Assuming 1111 stems/ha with 85% survival, these growth rates correspond approximately to volumes (outside bark) of 14 - 15 m3 of wood/ha/year on sites in Brazil and Venezuela, and 4 - 5 m3/ha/yr in Colombia. Since these data represent the mean of unimproved material from all provenances, substantially larger values should be expected from selected material from the best provenances planted on suitable sites.
