Abstract
The energy exchanges from a 23.5 m high rubber stand located in the tropical rain forest of Ivory Coast were determined using the energy balance-Bowen ratio method. The analysis shows that during the vegetative growing period (11 months) the radiation budget is nearly constant: it represents 72% of the global radiation. The distribution of available energy between latent and sensible heat depends on the leaf age, the air water vapour pressure deficit and the soil water availability. The amount of water vapour released in the atmosphere by the rubber forest represents 3 to 5 mm day−1 during nine months of the vegetative period and 1 to 3 mm day−1 two months before the leaf fall. Fluctuations of the canopy photosynthetic capacity are also dependent on soil water availability and leaf age.
