Clonal Propagation of Khaya senegalensis: The Effects of Stem Length, Leaf Area, Auxins, Smoke Solution, and Stockplant Age

Table 3

Main effects of Indole-3-butyric acid (IBA) on the percentage of rooted cuttings, the number of roots, the length of the longest root, and the number of secondary roots per rooted cutting of Khaya senegalensis. Means ± SE (standard error) followed by the same letter(s) are not significantly different at the 5% level according to Tukey’s multiple comparison test.

0 ppm	28 ± 8ab	7.9 ± 1.4a	2.59 ± 0.45ab	3.5 ± 0.9a
2500 ppm	30 ± 8a	10.0 ± 2.1ab	2.53 ± 0.35b	3.8 ± 0.8a
5000 ppm	28 ± 8ab	12.0 ± 2.1b	3.51 ± 0.50a	4.6 ± 0.9a
10000 ppm	26 ± 8b	17.1 ± 3.1c	3.27 ± 0.31ab	5.2 ± 1.0a
