Abstract:The seedlings of somatic hybrid wheat (Ⅰ-1-3) (Triticum aestivum × Agropyron elongatum) and its wheat parent (Jinan 177) were treated with different concentrations of NaCl to investigate the growth and Na+ and K+ contents in leaves, stems and roots. It was shown that the seedling weight of somatic hybrid was higher than that of wheat parent after treatment with salt for 6 days. The Na+ content both in hybrid and in wheat parent increased as NaCl concentration increased, but the Na+ content in the leaves and stems of the hybrid was significantly lower than that of the wheat parent．On the contrary．Na+ content in the roots of hybrid was higher．It implied that the hybrid had more vacuole compartment for sodium than the parent．However, the content in the leaves and stems of the hybrid was higherthan that in the wheat parent．Net Na+ uptake in hybrid was slightly higher than that in parent．It is indicated that the hybrid line possesses higher salt tolerance than the wheat parent.
