Resumen
Descripción
Measurements of photosynthesis and stomatal conductance were made on oil palms (3 clones (MK10, MK22 and MK04) with contrasting morphology and different genetic origins) at the Marihat Research Station in NorthSumatra in Indonesia. The results established a new level of reference for the maximal photosynthesis of oil palm equal to 31.6 Ámol m2s1. Analysis of variations of photosynthesis in response to environmental factors such as temperature or vapour pressure deficit (VPD) demonstrated the high sensitivity of maximal photosynthesis to these factors in Sumatra compared with observations in Cote d'Ivoire and in Benin. The differences observed within clones for the photosynthetic response to light and the sensitivity of maximal photosynthesis tovariations in VPD and temperature demonstrate the possible use of these physiological parameters for breeding.
