  • This paper compared the drought resistance of three seedlings of Acacia under different water stress by means of treating with polyethylene glycol 6000 (PEG-6000) solutions with different osmotic potentials to imitate the condition of water stress, furthermore, decided appraising physiological indexes of early drought resistance of seedlings. The result showed that the indexes of EC, RWC, RWD, Ssug and Fpro could be used as appraising indexes of early drought resistance of seedlings of Acacia, and concluded that the drought resistance of three tree species from strong to weak was A. crassicarpa, A. auriculaeformis, A. mangium.
