Abstract: Variations in the water regime promote changes in physiology and plant phenology by modifying patterns of growth and development.The aim of this research was to study physiological responses and changes in phenology of 'Navelate' orange trees submitted to different intensities of water stress in greenhouse.Stressed conditions were based on 50% and 25% of the field capacity.Gas exchange [photosynthesis (A), transpiration (E), stomatal conductance (gs), internal CO2 concentration (Ci), water use efficiency (WUE)] were analyzed in addition to growth parameters during 210 days.A completely randomized design was used, the results were submitted to variance analysis and when detected statistical difference, the means were compared by Tukey test at 5% probability.Water stress affected all gas exchange parameters of the exposed orange trees, limiting growth in diameter and height.Submission to amount of water lower than 50% of field capacity undertakes gas exchange, reducing plants Brazilian Journal of Development
