Fig 1. Epidermal cell size under condition of salt stress.

Two different hybrids, namely the salt-sensitive Lector (A) and the relatively NaCl-resistant SR03 (B), were raised in the absence (left, control) and presence (right, 100 mM NaCl) of an 8-day NaCl stress treatment. The size of the epidermal cells was measured in the youngest expanding leaf in a region that had emerged from the sheaths. Epidermal cell length (A), epidermal cell width (B) and epidermal cell surface area (C) are shown. The data represent the means of four biological replicates (n = 4), each run in triplicate ± SE. Sizes of 12 cells per technical replicate were quantified. Asterisks indicate significant mean differences between salt treatments and controls (*p ≤ 0.05 and **p≤ 0.01; ns = not significant; t-test). Photo in (A) amended from Geilfus [37].
