This paper evaluated the ability of cold resistance of three Acacia species coming from south subtrop icalareas and sequenced the cold resistance of the p rovenances on the basis of electrical conductivity. The resultsshowed that there was very significant diference for cold tolerance among the three Acacia species and theirp rovenances. The sensitizing range of low temperature for A. m ang ium. was 6 ℃, and 3 - 0 ℃ for A. au riculaeform is and A. crassicarpa. The strongest p rovenances of A. m angium, A. auriculaeform is and A. crassicarpa were17703, 19244, 17562 or 16598.
