Abstract
Plant growth, photosynthetic and physiological characteristics, fruit quality and yield were studied under simulated drought stress using CaCl2 solution to improve tomato fruit quality.
Under simulated drought stress, water potential and transpiration rate decreased, free water decreased and bound water increased.
Photosynthetic rate, stomatal conductance and intercellular CO2 were reduced.
Drought stress improved fruit quality, SSC, organic acid, and vitamin C, increased sugar/acid ratio, but decreased yields.
Under simulated drought stress, the number of fruits almost did not change but the weight per fruit was reduced.
Dry matter content per fruits increased, and the total dry matter content per section did not change.
