IBA(μM)	% Response	Mean no. of roots/shoots	Mean root length (cm)
0	0	0.0 ± 0.0e	0.0 ± 0.0e
100	80	3.1 ± 0.3d	1.7 ± 0.0d
200	82	3.4 ± 0.2d	1.9 ± 0.0cd
300	90	5.5 ± 0.1b	2.0 ± 0.1bcd
400	94	5.0 ± 0.1bc	2.5 ± 0.3b
500	95	7.0 ± 0.1a	3.1 ± 0.1a
1000	92	4.6 ± 0.1c	2.3 ± 0.1bc

Values represent means ± standard error of 20 replicates per treatment in three repeated experiments. Means followed by the same letter are not significantly different (P = 0.05) using Duncan’s multiple range test
