Abstract:

This experiment was carried out to assess the physiological property of Saussurea runcinata seedling under varying levels of NaHCO3 and Na2CO3 (0, 30, 60, 90, 120, 150 and 180 mmol/L). To explore the physiological property of Saussurea runcinata seedling under varying levels of NaHCO3 and Na2CO3, the Pro, soluble sugar, soluble protein and MDA contents of Saussurea runcinata were significantly higher than control, and the contents of roots were significantly higher than those of the leaves at the same alkali concentration of stress; the harm of Na2CO3 is greater than NaHCO3 to Saussurea runcinata.
