The data in Table 3 represent the biomass of each part of Sedum alfredii Hance at different Pb and Cd concentration treatments. Each abbreviation in the table indicates: S-F-W shoot fresh weight, S-D-W shoot dry weight, U-D-W underground dry weight, T-D-W total dry weight. The numbers after different letters in the same column of each treatment were significantly different (P < 0.05)
