Night-time transpiration (Enight) is potentially an important factor affecting whole-plant water balance and, thus, water use efficiency. The aims of the present study were: to evaluate night-time changes of stomatal conductance (gnight) and transpiration under different soil water availability...

In Mediterranean areas grapevine water use efficiency (WUE) is becoming an important issue as grapevine production and quality are largely dependent on irrigation, and given the large area of this crop in this region. Under semi-arid conditions, grapevine water consumption rises up to 700mm/year...
