The ability of maintaining turgor pressure, osmotic adjustment,capable of preserving and endurance of water separation capability were increased under elevated CO_2 concentrations,whereas the resistance of water separation capability decreased.Theε~max increased in normal water condition of Acer truncatum under 720μmol·mol~(-1)CO_2,and cytoderm more hardness and less elasticity.But in circle 3,ε~ decreased in light and middle drought conditions and increased in serious drought condition.(5) The branch 0,branch 1 and branch 2 of hydraulic conductivity of 7 trees increased along elevated CO_2 concentration.
