  1. Here, NAA α-naphthaleneacetic acid, IBA Indole-3-butyric acid, BAP 6-benzylaminopurine, Kn 6-furfuryl-amino purine. Each value represents the mean ± SE of three repeated experiments. Each mean value followed by the same letter does not differ significantly according to Duncan’s multiple range test (p ≤ 0.05). Marked in bold is the treatment that yielded the best result
