  abstract = {{C}limate change and fast extension in climatically suboptimal areas threaten the sustainability of rubber tree cultivation. {A} simple framework based on reduction factors of potential transpiration was tested to evaluate the water constraints on seasonal transpiration in tropical sub-humid climates, according pedoclimatic conditions. {W}e selected a representative, mature stand in a drought-prone area. {T}ree transpiration, evaporative demand and soil water availability were measured every day over 15 months. {T}he results showed that basic relationships with evaporative demand, leaf area index and soil water availability were globally supported. {H}owever, the implementation of a regulation of transpiration at high evaporative demand whatever soil water availability was necessary to avoid large overestimates of transpiration. {T}he details of regulation were confirmed by the analysis of canopy conductance response to vapor pressure deficit. {T}he final objective of providing hierarchy between the main regulation factors of seasonal and annual transpiration was achieved. {I}n the tested environmental conditions, the impact of atmospheric drought appeared larger importance than soil drought contrary to expectations. {O}ur results support the interest in simple models to provide a first diagnosis of water constraints on transpiration with limited data, and to help decision making toward more sustainable rubber plantations.},
