Phenotypic response of Z. japonica Steud. to salt stress. a Two materials with contrasting salt tolerances, Z004 (salt sensitive) and Z011 (salt tolerant), were exposed to 350 mM NaCl for 40 days. b The leaf firing of the Z004 and Z011 grasses after NaCl treatment for 40 days. c The relative shoot clipping dry weights of Z004 and Z011 after NaCl treatment for 40 days. d The relative verdure dry weights of Z004 and Z011 after NaCl treatment for 40 days. e The relative root dry weights of Z004 and Z011 after NaCl treatment for 40 days. The values are presented as the means ± SEs. The asterisks above the bars indicate significant differences between the respective values (p < 0.05)
