The content of different ions in trichomes of S. ferganica under salt stress. a Control (without salt treatment). b–c Microstructure of trichome surface after salt treatment (500 mmol·L− 1). d Contents of Na+, Cl−, K+, and Mg2+ in leaf mesophyll cells and trichomes. Scale bar in a, b, c is 20 μm. Lowercase letters indicate significant differences (P < 0.05) among different NaCl concentrations in mesophyll cells; uppercase letters indicate significant differences (P < 0.05) among different NaCl concentrations in trichomes. *,**: represents significant differences (P < 0.05 or 0.01) between mesophyll cells and trichomes at the same NaCl concentration. Values are means ± SD of at least three replicates
