“…In a parallel study conducted in the same experimental site we found a positive relationship between SLA and leaf photosynthetic nitrogen use efficiency (PNUE) (Delagrange et al 2008) and Kitajima (1994) and Walters et al (1993), among others, have reported higher photosynthetic rates and SLA values for pioneer species than for non-pioneers when growing under high light conditions. SLA is known to well predict photosynthetic capacity under high light conditions and particularly at The main factors included in the analyses were the functional type (pioneer or non pioneer) and the species nested under these groups Trees (2008) 22:585-596 591 fertile sites (Craven et al 2007).

We investigated biomass allocation and root architecture of eight tropical species with different successional status, as classified from the literature, along a size gradient up to 5 m. We focused on belowground development, which has received less attention than aboveground traits. A discriminant analysis based upon a combination of allocational and architectural traits clearly distinguished functional types and classified species according to successional status at a 100% success rate. For a given plant diameter, the pioneer species presented similar root biomass compared to the non-pioneer ones but higher cumulative root length and a higher number of root apices. A detailed study on the root system of a sub-sample of three species showed that the most late-successional species (Tabebuia rosea) had longer root internodes and a higher proportion of root biomass allocated to the taproot compared to the other two species (Hura crepitans and Luehea seemannii). Most pioneer species showed a higher leaf area ratio due to a higher specific leaf area (SLA). We conclude that the functional differences between pioneer and non-pioneer tree species found in natural forests were maintained in open-grown plantation conditions.

“…Condit et al 1993). However in sites with restricted water availability or on poor soils the use of more conservative non-pioneer species (with lower LAR and thus lower evaporative demands) or nitrogen-fixing species, such as Enterolobium, seems more appropriate (Craven et al 2007). …”

“…Photosynthesis, intrinsic water use efficiency, dark respiration, and foliar C:N ratios all vary among species and among sites with different rainfall regimes (Mulkey and Wright, 1996;Craven et al, 2007). Precipitation may be the most important climatic variable affecting tree growth in the seasonal tropics.…”

“…Our knowledge of biomass accumulation and partitioning under different regional climates must therefore be greatly improved (i) to fine-tune species selection criteria for plantations and agroforestry, and (ii) as a step towards understanding differential growth and survival of multiple species. Comparative studies performed along gradients of site conditions, or in different regional climates are particularly needed (Condit, 1998;Santiago and Mulkey, 2005;Craven et al, 2007;.…”

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