WATER STRESS AND ORANGE YIELD
The effects of different levels of water stress on orange fruit quality in different periods were examined in a six year experiment. The qualitative characters examined, i.e., rind thickness, juice content, acidity and Brix degree remained unaffected by the stress level, but were affected according to the period when stress was imposed. Giberellic and abscisic acid content as affected by water stress and subsequent rehydration was determined.
