Bar charts labeled A and B display the effect of different salt stress concentrations and PEG-6000 levels on leaf water content and relative conductivity, respectively, with significant differences indicated by letters and statistical notations. — Effects of combined drought and salinity stress on the water content of alfalfa leaves and the relative electrical conductivity of seedlings. (A) Leaf water content, (B) Relative conductivity. D, drought stress; S, salinity stress; D × S, interaction between drought stress and salinity stress. Different lowercase letters above bars indicate significant differences among treatments at P < 0.05. *, **, and *** indicate significance at P < 0.05, P < 0.01, and P < 0.001, respectively; ns indicates no significant difference.
