Exogenous calcium facilitated the carbon (A) and nitrogen (B) assimilation of tall fescue in salt environment. However, it showed no significant effect on Carbon Nitrogen ratio (C). Columns marked with different letters indicate statistic significant difference at P < 0.05 by Tukey's multiple range tests. “0-L” and “5-L” on the horizontal axis means experiments are carried out in shoots at 0 and 5 days after treatments (DAT), similarly, “5-R” represents roots at 5 DAT. Comparisons were carried out among the same tissue at same time, respectively.
