FIGURE 5.

Representative transverse semi-thin sections of leaves. The samples for this experiment were third- and fourth-node leaves from 2-week-old Z. xanthoxylum seedlings treated with 50 mM NaCl or without (control) for 7 days. All these sections were stained with toluidine blue. Semi-thin section of leaf from control (A) and NaCl treatment (B). Palisade cells from control (C) and NaCl treatment (D). Spongy cells from control (E) and NaCl treatment (F). The scale bars in (A,B) are 100 μm, while those in (C–F) are 50 μm.
