“…Morphological study was carried on the fresh samples of small twigs and cones of J. phoenicea (Schulz et al, 2003;Klimko et al, 2007;Guetet et al, 2009). Plant materials were collected in December 2011 from four coastal sites (Rimel, Laazib, Tabarka and Korbous) and four continental sites (Makther, Mallegue, J. Mansour and Dkhila) ( Table 1).…”

KEYWORDS Juniperus phoenicea Branches Cones Morphometry Taxonomy ABSTRACTThe 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.

“…Unlike the cultivated garlic (A. sativum L.), which has been the focus of several studies treating morphological, agronomic, and molecular characteristics (Maaß and Klaas, 1995;Baghalian et al, 2006), studies on rosy garlic are scarce. These studies are mainly dedicated to morphological (Guetat et al, 2008(Guetat et al, , 2009bZammouri et al, 2009), chemical (Najjaa et al, 2007), and karyological aspects (Guetat et al, 2009a), and recently to molecular identification (Guetat et al, 2010).…”

In North Africa, Allium roseum L. has been treated as a polymorphic species comprising 12 different taxa. More than 80 individuals in the Allium roseum complex were sampled from 20 populations at different localities in Tunisia and investigated karyologically. Basic chromosome number was confirmed as x = 8. Three cytotypes, diploid (2n = 2x = 16), triploid (2n = 3x = 24), and tetraploid (2n = 4x = 32), were found. Polyploidy was recorded for the first time for this species in Tunisia. Most of the populations were diploid (17 populations), whereas two populations were tetraploid and only one was triploid. The chromosome set of studied populations is nonuniform at the species level and within cytotypes. The 45S and 5S ribosomal genes (rDNA) were visualized by fluorescent in situ hybridization for the A. roseum polyploid complex. The diploid showed three loci 45S rDNA; the triploid and tetraploid showed 9 and 12 signals, respectively. However, 5S rDNA showed 2 signals for the diploid genome and 4 signals for both triploid and tetraploid. The 45S rDNA results showed intra-and interpopulational numerical variation. However, the data obtained with the 5S rDNA genes revealed a highly conserved distribution of these ribosomal families in the chromosomes of individuals from each population, as well as among the analyzed populations.
