Fig. 1. Stem biomass (A), root biomass (B), total biomass (C) and leaf performance (D) of Populus deltoides and P. cathayana under different treatments (mean ± SE). CK, control; D, defoliation; Sa, salt stress; Sa-D, salt stress and defoliation; Sp, species. Different lowercase letters indicate significant differences among treatments (p < 0.05). **, 0.001 < p ≤0.01; ***, p ≤ 0.001.
