Pigmented and non-pigmented callus percentages in presence of different concentrations of auxin hormones. Mean comparisons were performed by Tukey’s multiple range tests

	Non pigmented callus (%) mean ± SE	Pigmented callus (%) mean ± SE
IAA (mg.L-1)
0.2	There were no non pigmented callus	68.33 ± 0.28
0.5		56.67 ± 0.17
1		36.67 ± 0.24
2, 4-D (mg.L-1)
0.2	41.66 ± 0.38	30 ± 0.54
0.5	61.66 ± 0.37	15 ± 0.33
