Effect of different Indole-3-butyric acid (IBA) concentrations on in vitro rooting of B. senegalensis shoots after 4 weeks of culture.

IBA (mg/L)	Number of roots per rooted shoot	Root length (cm)	Rooting percentage (%)
0.0	1.0 ± 0.3	0.4 ± 0.1	67
0.25	1.2 ± 0.4	0.5 ± 0.2	67
0.5	0.3 ± 0.2	0.1 ± 0.1	33
1.0	0.4 ± 0.2	0.3 ± 0.1	33

Each value represents the mean + standard error of at least 10 replicates.
