This study compared the effects of salt (NaCl) stress on growth, photosynthesis and solute accumulation in seedlings of the three poplar (Populus bonatii) cultivars Populus × BaiLin-2 (BL-2), Populus × BaiLin-3 (BL-3), and Populus × Xjiajiali (XJJL). The results showed that BL-2 and BL-3 could not survive at a salinity level of 200 mM but XJJL grew well. The effect of moderate salt stress on leaf extension of the three cultivars was only slight. At a high level of salinity, however, NaCl clearly inhibited leaf extension of BL-2 and BL-3, whereas it did not affect that of XJJL, and the net photosynthetic rate (P N) in XJJL was much higher than those of BL-2 and BL-3. The lower P N of BL-2 and BL-3 might be associated with the high concentration of Na+ and/or Cl- accumulated in the leaves, which could be toxic in photosynthesis system. In summary, the greater salt-tolerance of XJJL compared with that of BL-2 and BL-3 might be explained by the higher P N and photosynthetic area, the lower Na+/K- ratio and Cl- in the leaf, and the greater accumulation of soluble sugars and SO4 2-.
