Intraspecific variation and morphometric analysis of Juniperus phoenicea L. branches and cones from Tunisia
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2016, Vol 4, Issue 0
Abstract
The intra- and inter populational geographic variation of eight distant populations of Juniperus phoenicea L. originating from Tunisia was examined biometrically on the basis of morphological-key characters of branches and cones. Seven and eight qualitative and quantitative (measured) traits of each branches and cones were studied on 45 and 29 vouchers, respectively. The principal component analysis (PCA) and hierarchical cluster analysis (HCA) of euclidean distances were performed to verify the hypothesis of geographic differentiation and for the existence of two J. phoenicea L. subspecies. The sampled populations differed significantly from one another, while the intra-populational variation was lower. Two major groups emerged on the PCA and HCA results, separating the continental populations from the coastal ones. Compared to the morphological traits of J. phoenicea subspecies in the literature and the basic flora, we confirm the existence of two J. phoenicea taxa: J. phoenicea ssp. turbinata was the reported from the coastal sites and J. phoenicea ssp. phoenicea located in the continental ones.
