Morphological analysis of wheat treated with PDS solution under salt stress. Three-day-old wheat was treated with or without 2000 ppm PDS solution with or without salt stress for 2 days. The bar in the left panel indicates 10 mm in the picture (A). As morphological parameters, leaf length (B), fresh leaf weight (C), main root length (D), and total root fresh weight (E) were analyzed at 5 days after sowing. The data are presented as mean ± SD from three independent biological replicates. As independent biological replicates, more than 20 seeds were sown for each treatment for each replicate on different days. Student’s t-test was used to compare values between two groups. Asterisks indicate significant changes (*, p ≤ 0.05; **, p ≤ 0.01).
