* within the same row and within each type of conditions (non-saline and saline conditions) indicates significant differences from its respective control, # within the 100 mM NaCl control column indicates significant differences from normal conditions control, both according to Fisher’s protected LSD (least significant differences) (p ≤ 0.05 ). S.E. = standard error.
