Not much is known about the influence of leaf position on photosynthesis in water-stressed leaves. We do know that stomatal control of water loss is an early plant response to water deficit under field conditions ( Chaves, 1991 ; Cornic and

poor postproduction conditions are estimated to result in 5% to 20% of unsalable crops ( Healy, 2009 ), and water stress is one of the major causes of diminished aesthetic quality and salability of plants. Therefore, it is highly desired to minimize
