The biomass of tropical forests plays an important role in the global carbon cycle, both as a dynamic reservoir of carbon, and as a source of carbon dioxide to the atmosphere in areas undergoing deforestation. However, the absolute magnitude and environmental determinants of tropical forest biomass are still poorly understood. Here, we present a new synthesis and interpolation of the basal area and aboveground live biomass of old-growth lowland tropical forests across South America, based on data from 227 forest plots, many previously unpublished. Forest biomass was analyzed in terms of two uncorrelated factors: basal area and mean wood density. Basal area is strongly affected by local landscape factors, but is relatively invariant at regional scale in moist tropical forests, and declines significantly at the dry periphery of the forest zone. Mean wood density is inversely correlated with forest dynamics, being lower in the dynamic forests of western Amazonia and high in the slow-growing forests of eastern Amazonia. The combination of these two factors results in biomass being highest in the moderately seasonal, slow growing forests of central Amazonia and the Guyanas (up to 350 Mg dry weight ha−1) and declining to 200?250 Mg dry weight ha−1 at the western, southern and eastern margins. Overall, we estimate the total aboveground live biomass of intact Amazonian rainforests (area 5.76 × 106 km2 in 2000) to be 93±23 Pg C, taking into account lianas and small trees. Including dead biomass and belowground biomass would increase this value by approximately 10% and 21%, respectively, but the spatial variation of these additional terms still needs to be quantified.

The improvement of sweet sorghum for biofuel traits is gaining attention globally because of its promising role in the growth and sustainability of the ethanol production chain. The aim of this study was to assess the heterosis on ethanol yield and related agro-industrial traits in sweet sorghum under tropical conditions. Thirty hybrids were generated from a partial diallel scheme using three juicy stem non-sweet female lines (A) with cytoplasmic male sterility crossed with ten sweet sorghum male fertile restorer lines (R). The hybrids, parental lines, and two checks were evaluated in three environments in Brazil. Heterosis in sweet sorghum was observed for ethanol yield (ETH) and several yield components. Four hybrids showed positive heterosis on the R-line basis for ETH. The heterosis was higher for PH (plant height), GMP (green or fresh biomass production), and tons of brix per hectare. The parental A and R-lines diverged in contributing to the heterosis. The lines BR008A and CMSXS644R have been highlighted for ethanol yield and can be included in future A and R-line development. |
