Potted seadlings of Pinus koraiensis,Fraxinus mandshurica,Juglans mandshurica,Tilia amurensis,and Quercus mongolica,which are five dominant species in the Korean pine broadleaf forest at Changbai mountain,were grown in different soil moistures.We designed three soil moisture scenarios:85%～100%(high water,CK),65%～85% (medium water,MW) and 45%～65% .(low water,LW) of field water-holding capacity.The results show that characteristics of typical drought-resistance on the leaves are significantly developed.The net photosynthetic rate and water use efficiency of F. Mandshurica were higher compared with CK at MW.The net photosynthetic rate and water use efficiency of other 4 tree species at CK were lower than those at MW and LW.The transpiration rate of 5 tree species responses differently to various soil water status.
