Abstract: In order to evaluate the waterlogging tolerance of fig（Ficus carica Linn.），potted-cuttings of 12 cultivars were used to compare the effects of waterlogging on leaf pigments，antioxidant enzyme activities，reactive oxygen metabolism，malonaldehyde（MDA），proline，soluble protein content and the chlorophyll fast fluorescence characteristics under full flooding condition. The results showed that waterlogging significantly reduced the content of leaf pigment and soluble protein in all cultivars，but the superoxide anions，MDA and proline contents were significantly increased under the stress；Nevertheless，the amplitudes were different dependent upon cultivars. Furthermore，the leaf chlorophyll fast fluorescence characteristics，including prompt fluorescence of OJIP curves，PSⅠ and PSⅡ reaction center activities and photosynthetic capacity indexes of fig cultivars were significantly impaired by waterlogging stress，most of them were closely correlated with waterlogging tolerance. According to the leaf injury index and the correlated physiological parameters under waterlogging，the 12 cultivars were classified into four groups by fuzzy clustering of SPSS20 software，where 102A，105A and 121E were waterlogging tolerant，106A，113C，107B and 112C were medium tolerant，101A，110C and 114C were weak tolerant，and 117D and 118D were sensitive cultivars.
