Abstract Three-month-old mulberry (Morus alba L.) cultivars (salt tolerant cv. S1 and salt sensitive cv. ATP) were subjected to different concentrations of NaCl for 12 d. Leaf area, dry mass accumulation, total chlorophyll (Chl) content, net CO2 assimilation rate (P N), stomatal conductance (g s), and transpiration rate (E) declined, and intercellular CO2 concentration (C i) increased. The changes in these parameters were dependent on stress severity and duration, and differed between the two cultivars. The tolerant cultivar showed a lesser reduction in P N and g s coupled with a better C i and water use efficiency (WUE) than the sensitive cultivar.
