Abstract

Abstract: In this study, we select spring wheat (yongliang4) that main grow in Midwest Inner Mongolia. Pot experiments were conducted under laboratory to study the effects of soil salinity levels (0.41%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%) and three soil varieties (NaCl, NaCl+Na₂SO₄, Na₂SO₄) on seedling stage growth of wheat. The results showed that emergence rate, shoot length of wheat, while they diminished with increasing soil salinity. Among the three salt, Salt stress was NaCl>NaCl+Na₂SO₄>Na₂SO₄. Lowness concentration of salt stimulate, the root growth of wheat was more adversely affected compared to shoot growth by soil salinity. The results will has important referenced value to wheat production to salt-affected cropland.

Key words: Salt stress, Wheat, Seedling stage growth, Salt-tolerance
