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

Table 5

Main effects of stockplant maturation, Naphthalene acetic acid (NAA) and NAA in combination with Indole butyric acid (NAA + 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.

Main effects		Rooting (%)	No. roots/rooted cutting	Longest root length (cm)	No. secondary roots
