Transpirations of one-year-old seedlings of two natural oak species (Ouercııs libaııi and O. frainetto) vvere nıeasured in dry period (late August). Seedlings of Q. libaııi began to control their stomas at 5th minutes and closed the stomas at 45,h minute with higher vvater potentials. This species also lost relatively less vvater than the other in comparison vvith dry vveight. Q. frainetto closed the stomas at 180,h minute. The results shovv that compared to Q. frainetto, O libani is found to be less sensitive to drought stress and more desiccation avoidant.
