  1. Percentage of shoot rooting were measured 35 days after shoots were transferred into medium containing 0.001, 0.005, 0.01, or 0.05 μM IBA, respectively. Each experiment was replicated five times, and each replicate consisted of 30–50 shoots. Values represent the mean ± SD. Values followed by different letters are significantly different (α = 0.05) by ANOVA
