The effect of salt stress on growth parameters of A. hierochuntica and Arabidopsis. (A–C) Plants grown on soil were exposed to incremental increases of NaCl concentration, and were harvested 1 week after the final NaCl concentration was reached. (A) Shoot FW. (B) Shoot DW. (C) Rosette leaf area. (D,E) Seedlings were grown on MS medium in vertical plates without NaCl and then transferred to fresh vertical MS plates supplemented with the indicated NaCl concentrations. (D) Arabidopsis root relative growth rate (RGR). (E) A. hierochuntica root RGR. Data are expressed as a percentage of control (0 mM) RGR on day 1 after transfer to salt stress. Data are mean of three to four experiments ± SD. Each independent experiment comprised four replicate plates with 10 seedlings per plate. For both soil and plate experiments, bars or time points with different letters indicate a significant difference at P < 0.05 (Tukey HSD test). FW, fresh weight; DW, dry weight.
