Figure 3From: Variation of chemical composition of essential oils in wild populations of Thymus algeriensis Boiss. et Reut., a North African endemic SpeciesDendrogram obtained by cluster analysis based on Euclidean distance performed on the essential oil compounds of the 8 T. algeriensis populations during two phenological stages. PiSj represent population i (i = 1-8) at the vegetative stage (S1) or at the flowering stage (S2). Coding numbers of populations' locations: see Table 1.Back to article page
