The difference esti­ mated be caused by cuticular resistances for transpiration appeared large gap at surface. Furthermore, differences were found between profiles on adaxial abaxial surfaces, which considered more turbulent higher tran­ spiration rate conditions such as temperature, saturation deficit wind velocity ambient outside affected density, these condi­ tions closely related made resistance lower temperatures, deficits velocities.
