Abstract: This seedling test used provenances of four countries, sixteen areas from Central America. We surveyed the seedling height and the ground diameter increment of seedling and carried out the analysis of variance when 55 monthes old. We find out: Pinus oocarpa of different provenances, at the same testing situation, the yariance of seedling height and ground piameter are very striking. We have preliminarily selectcd some provenances of those increase more than 114- 126% of control, one of them which comes from Honduras call be used in fores- tation at those places that lower than 1200 meters above sea-level at southern Yunnan.The test has also investigated the geographical variation regularity of mor-phological characters of Pinus oocarpa and the relations between them.
