Provenance productivity in Pinus caribaea and its interaction with environment
Data are reported for 19 provenances grown at some or all of 16 sites in the CFI international provenance trials which represent the full range of climatic conditions suitable for afforestation with the species. Interactions between provenance and locality were analysed for ht., diam., bark thickness and % and vol. u.b., and found to be small but statistically significant; e.g. for vol. u.b. locality accounted for 67% of variation, locality and provenance for 79% and locality, provenance and interaction for 80%. However, important reversals in ranking between inland and coastal provenances of P. caribaea var. hondurensis occurred at environmental extremes. Productivity of P. caribaea var. hondurensis was superior to P.c. var. caribaea and var. bahamensis at all localities, and there were significant differences in productivity between provenances of P.c. var. hondurensis.
