The study about the effects of different NaCl concentrations at 0,150,300,and 500 mmol· L on 40-day-old seedling of Amaranthus tricolor showed that the plant growth, photosynthetic rate, rate of transpiration and opening degree of stoma were all restrained with different degrees after lasting 5 d. The contents of Na+ and Cl- in the leaf and root of Amaranthus tricolor increased remarkably with the raise of the concentration of NaCl. The contents of betaine in all treatments with different concentrations of NaCl increased.
