Abstract
Data on stemwood biomass and mean annual biomass increment ( MABI) for seven tropical tree plantation species were synthesized from the literature to evaluate species adaptibility and potential yields in different environments. Stemwood biomass ranged from < 1 to 712 t ha −1, and MABI ranged from about 1 to 30 t ha −1 year −1 in plantations of Pinus caribaea, Tectona grandis, Pinus patula, Gmelina arborea, Cupressus lusitanica, Eucalyptus grandis, and Albizia falcataria. Stemwood biomass and MABI varied with species, plantation age, and climate. Linear models best described the relationship between stemwood biomass and age of plantation, and the slopes of these equations ( MABIs) varied among species and among life zones for a given species. Significant relations were found between stemwood biomass and MABI and water availability (the ratio of temperature to precipitation, T/ P). In general, stemwood biomass and MABI decreased at high (arid) and low (very humid) T/ P ratios. Each tree species had an optimal T/ P at which its maximum stemwood biomass and MABI occurred. Other site factors, such as soil fertility, modified plantation response to climate.
