FIGURE 1.

NaCl treatment (50 mM) for 7 days increased the survival rate and durability of 2-week-old Zygophyllum xanthoxylum seedlings compared to controls when water was withheld. (A) Water lost by evapotranspiration per box on the 7th day of NaCl treatment. (B) Survival rate versus days that water was withheld; (C,D) show representative photographs of control and NaCl-treated plants taken after 19 days without water, respectively. Bars denote the mean ± SD of between three and four replicates; each replicate in (A) involved 12 plants. Bars with different letters are significantly different at the level of 0.05.
