Abstract: The geographical provenance test of Pinus caribaea Mor. var. hondurensis Barr. et Golf which provenances were introduced from four countries, thirteen areas of Central America has been earring out for eight years, the tree height, diaemeter breast height, needle length, branch numbers and crown area were surreyed and the analysis ofvarance and the ana-lysis of correlation were made, It has been verified -that the variance among provenances and the correlation of increase and geographical distribution of provenance are not obvious. Other-wise, the correlation between seedling stage growth and young stage growth for each provenance are very distinct and the provenance with smaller ceofficent of variation on five main characters has greater tree volume.

Key words: Pinus caribaea var. hondurensis
