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

Table 1

Effects of cutting length 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.

Length	Rooting percentage	No. roots/rooted cutting	Longest root length (cm)	No. secondary roots
5 cm	53 ± 16a	1.8 ± 0.3a	5.62 ± 1.38a	9.5 ± 4.1a
10 cm	47 ± 12a	2.0 ± 0.3a	4.10 ± 1.38a	3.9 ± 2.3a
15 cm	43 ± 16a	1.8 ± 0.2a	4.30 ± 0.32a	3.0 ± 1.7a
20 cm	63 ± 3a	3.0 ± 0.6a	5.16 ± 1.05a	7.7 ± 2.0a
