Abstract

Plantation growth of mahogany (Swietenia spp.) and teak (Tectona grandis) and the performance of teak and Spanish cedar (Cedrela spp.) provenances located in subtropical dry and moist life zones. are summarized for St. Croix, U.S. Virgin Islands. Hybrid mahogany (S. macrophylla x S. mahagoni) from St. Croix had the best form and growth rate of all tree species tested. The surviving five provenances showed 39 and 59 percent survival at 16 years in Estate Thomas and Hams Bluff, respectively. Growth rates for the Belize provenance at Estate Thomas and the Mexican provenance at Hams Bluff were superior to others; their survival rates were 66 and 89 percent, respectively. Testing of six provenances of teak showed significant differences in dbh and height, with the Tamilnadu, India provenance growing most ·rapidly, but having the highest mortality.
