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

Table 6

Main effects of low concentrations of smoke solution and immersion time 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.

Main effects		Rooting Percentage	No. roots/rooted cutting	Longest root length (cm)	No. secondary roots
Smoke	0%	100 ± 0a	10 ± 0.3a	2.92 ± 0.17a	4 ± 0.4a
solution	5%	88 ± 3b	7 ± 0.4b	3.28 ± 0.20a	6 ± 0.8a
	10%	93 ± 3ab	7 ± 0.3b	3.31 ± 0.28a	5 ± 0.8a
Immersion	30 min	92 ± 3a	8 ± 0.4a	3.01 ± 0.25a	5 ± 1a
time	60 min	93 ± 3a	8 ± 0.6a	3.10 ± 0.24a	5 ± 1a
	120 min	97 ± 2a	8 ± 0.5a	3.22 ± 0.26a	5 ± 1a
	180 min	91 ± 4a	8 ± 0.6a	3.34 ± 0.26a	6 ± 1a
