Abstract Several pieces of research suggest that leaf liquid-path conductance (K1) may be smaller in evergreen species (EG) than in deciduous species (DC), coexisting in tropical dry forests. This was investigated in four DC and two EG in a tropical dry forest in Venezuela. The K1 (kg m-2 MPa-1 s-1) were consistently lower in EG (8.4 × 10-5) than in DC (12 to 20 × 10-5). Differences in water potential (ΔΨW) inside the leaves were calculated using K1 values in connection with maximum transpiration rates measured in the field. It was found that ΔΨW was about 1.9 MPa in EG, intermediate for one DC (Pithecellobium dulce, 1.7 MPa) and minimum for other DC (1.0 to 1.3 MPa).
