Biomass distribution among tropical tree species grown under differing regional climates

摘要: In the Neotropics, there is a growing interest in establishing plantations of native tree species for commerce, local consumption, and to replant on abandoned agricultural lands. Although numerous trial have been established, comparative information performance trees under different regional environments generally lacking. this study, we evaluated accumulation partitioning above-ground biomass 16 two exotic replicated selection trials Panama humid dry environments. Seven 18 accumulated greater total at site than over two-year period. Speciesspecific among leaves, branches trunks was observed. However, wide range found (from 1.06 kg Dipteryx panamensis 29.84 Acacia mangium Soberania) justified used an Aitchison log ratio transformation adjust size. When adjusted size, majority these differences proved be result ability support components rather sites. These findings were confirmed by ANCOVAs Aitchison-transformed non-Aitchison-transformed variables. comparisons, basal diameter, height diameter breast robust predictors pooled data from both sites, but variables had little predictive power. © 2010 Elsevier B.V.
