Abstract: This paper gives the results of wheat stomatal resistance influenced by environmental factors. The analysis method used is multiple regression. The results explain that: soil water potential in the root zone is the major factor that influences stomatal resistance. The effect of environmental factors to abaxial stomata and adaxial stomata are different: the abaxial stomatal resistance is mainly influenced by soil water potential, but the adaxial stomatal resistance is mainly influenced by air temperature and air humidity.
