Effect of powder and liquid auxin formulations on silver damage. Unrooted IBA-coated (cv. Baltica) cuttings were dipped in water for 30 min. Non-coated cuttings were dipped in an equimolar concentration of 4000 ppm or water. Control cuttings did not receive a water dipping treatment. Bars (mean ± SEM, n = 13–15) represent the cumulative silver damage expressed as damaged leaf area in mm². Different letters indicate significant differences among groups as determined by Kruskal–Wallis followed by Games–Howell multiple post hoc comparison (p < 0.05).
