Intraspecific Morphological Variations among the Populations of Milicia excelsa, Pouteria adolfi-friedericii, and Prunus africana in Different Natural Forests of Southwest Ethiopia

Table 2

Principal component analysis (PCA) showing the effect of morphometric in clustering the populations of M. excelsa, P. adolfi-friedericii, and P. africana measured at the different forests.

	M. excelsa		P. adolfi-friedericii		P. africana
	PC1	PC2	PC1	PC2	PC1	PC2
Stem height	−0.16	0.58	0.73	0.23	−0.06	0.79
DBH	−0.99	−0.13	0.12	0.88	0.07	−0.59
Bole length	−0.04	0.80	0.67	−0.41	−0.99	−0.09

ANOVA test of the significance of the effect of parameters showed all morphometric parameters, i.e., DBH (F = 156.6, p ≤ 2e − 16), bole length (F = 13.34, p = 1.82e − 07), and stem height (F = 19.27, p = 1.2e − 09) have highly significant effect on the variation of the populations of M. excelsa at , i.e., DBH @PCA1, stem height and bole length both @PCA2. However, only bole length (F = 109.2, p = 7.5e − 05) has highly significant effect on the variation of the populations of P. adolfi-friedericii at , and similarly, only bole length (F = 118.7, p = 0.008) has a very significant effect on the variation of the populations of P. africana at .
