“…S. muricatus populations originating from subhumid or dry-subhumid Mediterranean climate zones showed greater leaf dimensions (length, width and length of the stipule) when compared with those originating from semi-arid zones. Similar results were found by Zoghlami & Zouaghi (2003) for Astragalus hamosus L. and by Davies & Young (1967) for white clover ( Trifolium repens ).…”

SU MMARYPrickly scorpion's tail (Scorpiurus muricatus L.) is a self-reseeding annual legume widely distributed in natural pastures of the Mediterranean area and appreciated by farmers for its productivity, forage quality and palatability. Twenty-eight natural populations were collected throughout Sicily in 2005; two field experiments were carried out in 2005/06 in a hilly area of the Sicilian inland to assess the genetic variation based on pheno-morphological and agronomic characters. The phenomorphological traits observed were analysed using a principal component analysis (PCA). The first four components of PCA (eigenvalues >1) explained 0 . 84 of the total variation. Similarities obtained by PCA were investigated by means of cluster analysis, which clearly identified five clusters.The pheno-morphological and agronomic traits were mainly affected by latitude of the collection site (0 . 69 of the correlations were significant), spring rainfall (0 . 63) and rain days per year (0 . 63). Altitude was not significantly correlated with any of the traits.A strong positive correlation was found between the days to the first flower and spring rainfall at the collection site. Populations originating from subhumid or dry-subhumid Mediterranean climate zones showed greater leaf dimensions when compared with those originating from semi-arid zones. Seed weight decreased with increasing number of rain days per year and spring rainfall. Populations from drier environments showed, on the whole, a more prostrate growth habit. Dry matter yield at spring cut exhibited a significant correlation with latitude (positive) and longitude (negative). Seed production was highly correlated with spring rainfall, number of rain days per year and latitude of collection site. The presence of a large diversity among populations appears to be valuable when searching for suitable S. muricatus material to exploit in pastures and crop-livestock farming systems of Mediterranean areas.

“…Milkvetch is a hard droughttolerant plant, with a high seed productivity (Zoghlami and Zouaghi, 2003), whose prostrate growth makes it a potentially useful species for soil protection in Mediterranean areas (Meloni et al, 2000). Button medic, due to its high-quality forage for livestock (Derkaoui et al, 1993;Zhu et al, 1996) and high seed productivity (Conway et al, 2001), is considered a potential species for pasture improvement in semi-arid zones (Meloni et al, 2000).…”

“…Koch, rarely noted as scorpion's tail, is a species that belongs to the family of Fabaceae plants, genus Coronilla. Since antiquity, various benefits of this genus have been mentioned, involving its use as a medicinal plant due to the occurrence of cardiac glycosides including furanocoumarins and coumarins, in several species (Zoghlami and Zouaghi, 2003). Indeed, among the Fabaceae family, furanocoumarins, especially psoralen, bergapten, xanthotoxin, are produced only by two genera, which are Psoralea and Coronilla genera (Szewczyk and Bogucka-Kocka, 2012).…”

The Tunisian area flora has a diverse and interesting vegetation cover. To date, many species, however, are not sufficiently explored and properly exploited. Despite their medicinal potential, Coronilla scorpioides (L.) W.D.J. Koch species has still not been studied. In this study, we aim to investigate the genetic diversity and the population structuring of 10 Tunisian populations. Ten DNAs pooled represented the populations of C. scorpioides species are used in this molecular analysis. Bulked segregant analysis (BSA) was used in order to identify a genetic polymorphism associated to a specific trait by comparing DNA pools with contrasting phenotypes by sequence-related amplified polymorphism (SRAP) markers. Moreover, 10 DNA samples for each population were examined by five retrotransposon-microsatellite amplified polymorphism (REMAP) combination in order to elucidate the genetic composition of this species. Our results suggested that C. scorpioides species have a high genetic diversity that can be related to their geographical distribution. This genetic richness could be the source of their agronomic variability in which two contrasted populations originated from Kairouan (P210 and P224) were genetically distinguished by the BSA-SRAP method. The occurrences of evolution were elucidated, and the ancestral populations were revealed. As the first research based on the genetic structuring and diversity of C. scorpioides, our finding illustrates the affluences' biodiversity of Tunisian area and the genetic richness of the studied species. This study could be the genetic guideline of C. scorpioides species that can be used to meet the needs of medicine and the national economy.
