SEM images. 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. (A,E) Adaxial stomata in control plants. (B,F) Abaxial stomata in control plants. (C,G) Adaxial stomata in NaCl-treated plants. (D,H) Abaxial stomata in NaCl-treated plants. Scale bars in (A–C), and (D) are 20 μm, while those in (E–H) are 4 μm. Scanning electron microscope (SEM) analysis of leaves on the 3rd–4th nodes of 2-week Z. xanthoxylum seedlings treated without (Control) or with 50 mM NaCl (Na) for 7 days. (A,E) Adaxial stomata in control plants. (B,F) Abaxial stomata in control plants. (C,G) Adaxial stomata in Na treatment plants. (D,H) Abaxial stomata in Na treatment plants. Scale bar: (A–D) 20 μm; (E–H) 4 μm.
