Effect of salt stress on trichome development in S. ferganica. a–c, e–g, i–k, m–o Cytological changes in the trichome cells during true leaf development under NaCl treatment. d, h, l, p Trichome length measurements corresponding to a–c, e–g, i–k, and m–o, respectively. a–d Germination for 36 h; e–h 40 h; i–l 54 h; m–p 60 h. a, e, i, m H2O; b, f, j, n 100 mmol·L− 1 NaCl; c, g, k, o 300 mmol·L− 1 NaCl. Scale bar: a–c, e–g, i–k, m–o, 25 μm. Different lowercase letters above columns indicate significant differences (P < 0.05 or 0.01) among different NaCl concentrations at the same developmental time. Values are means ± SD of at least 10 replicates. CC: cotyledon cell; TC: trichome cell; M1: mesophyll
