对约旦安曼常见条件下生长的苹果、杏、葡萄、橄榄和桃子的选定水关系参数进行了每日检查。该研究的目的是确定水关系特征是否存在差异，这些差异可用于预测约旦不同地点或水资源有限的类似干旱地区的这些作物的用水量。苹果的蒸腾量最大，其次是桃子。杏、橄榄和葡萄具有相似的蒸腾速率，并且这些物种每单位叶面积损失的水分比桃或苹果少。苹果和橄榄的叶片电导率在下午达到最大，而桃和杏的叶片电导率在中午达到最大值；葡萄出现最早的最大叶导。葡萄的正午木质部压力潜力最高，橄榄最低，苹果、杏和桃处于中间。苹果和橄榄似乎具有最快恢复黎明前木质部压力的潜力。对水流的液体路径阻力的估计在苹果中最低，在橄榄中最高。结果表明，这些物种代表了响应常见湿度状况的替代植物策略。
Selected water-relations parameters were examined on a diurnal basis for apple, apricot, grape, olive and peach grown under common conditions in Amman, Jordan. The study objective was to determine if there were differences in water-relations characteristics that could be useful for the prediction of water use by these crop plants at various sites in Jordan or in similar arid areas with limited water.Transpiration was greatest in apple, followed by peach. Apricot, olive and grape had similar transpiration rates, and these species lost less water per unit leaf area than peach or apple. Apple and olive reached maximum leaf conductance in the afternoon, while peach and apricot had maxima at mid-day; grape had the earliest maximum leaf conductance. Grape had the highest midday xylem pressure potential and olive the lowest, with apple, apricot and peach being intermediate. Apple and olive appeared to have the most rapid return to pre-dawn xylem pressure potential. Estimates of the liquid pathway resistance to water flow were lowest in apple and highest in olive. Results suggest that these species represent alternative plant strategies in response to a common moisture regime.
