The good growth of Populus alba x P. glandulosa was shown at the foothill of the mountain where good soil moisture was available, but its growth was poor at the upper part of the mountain where soil moisture was limitted. Stomatal frequency, stomatal size and transpiration rates that affect soil moisture demand were determined in order to know how this characters was inherited from its parents. Number of stomata per mm2, length and width of stomata from the abaxial leaf and transpiration rate (g/cm2) per day in P. alba x P. glandulosa showed intermediate values between those of their parents, while P. alba showed the highest values and P. davidiana the lowest values
