Abstract: Daily changes of stomatal conduction of Salix gordejevii decreased after 8 a.m. The value of stomatal conductance was higher on lower epidermis than upper one, and the stomata of low epidermis were more sensitive to the environmental condition. The value of stomatal conduction and the cell water parameter of Salix gordejevii was different during growth season. The drought resistance ability of Salix gordejevii varied at different part of sand dunes and different seasons. The shrub possessed highest drought resistance in May and June. Cell turgor pressure was always positive in humid July, which implied that although the cell turgor pressure of Salix gordejevii changed with environmental condition and stomatal regulation, the growth of plants was not affected.
