Abstract

Saffron (Crocus sativus L.) is an autumnal herbaceous triploid plant; it is the source of saffron spice, recognized as the most expensive spice in the world. In this study, genetic diversity among 14 saffron accessions collected from different ancestral geographic areas in Morocco, Greece and France were assessed using inter-simple sequence repeats (ISSRs) markers system. Ten ISSR primers were amplified into a total of 143 fragments, of which 44.05 % are polymorphic with an average of 6.3 polymorphic fragments per each primer and average of polymorphic information content (PIC) of 0.236. ISSR markers proved to be a powerful tool for assessment of genetic diversity among saffron accessions. Cluster analysis using unweighted pair group method with arithmetic mean (UPGMA), based on Jaccard's similarity coefficient and supported by the principal coordinate analysis (PCoA), divided the studied accessions into three major groups, and showed that genetic distance is independent of geographical distance. In this paper, we report for the first time the level of genetic diversity among Moroccan saffron; this information allows an unequivocal development of a suitable approach for the conservation of C. sativus germplasm and reduce its genetic erosion.

Abstract

Pyrus mamorensis Trab. commonly called “wild pear” was considered for long time as an endemic of the Mamora forest of Morocco (north-west). Although lack of protection and it is threatened with extinction in its range, this tree is of great interest due to its ecological and medicinal properties. This study focused on evaluation of volatiles in Pyrus mamorensis for its valorisation as a natural resource. So, the volatile compounds from different parts (leaves, stems, fruits, and flowers) were investigated after extraction by cold maceration in ethyl ether and analyzed by gas chromatography coupled to the mass spectrometry (GC - MS). Thirty one (31) compounds were identified and quantified including fifteen (15) terpenes, seven (7) alcans, two (2) aldehydes, four (4) esters and three (3) allyl alkoxybenzen derivatives. Estragol was the dominant component of the plant and that was only detected in leaves (83,09 %), while hexadecane (36,92 %) and allyl hexanoate (29,39 %) were mainly detected in the stems. The fruits showed relatively high levels (20,59 %) of benzyl butanoate, whereas in the flowers, limonene is the most abundant constituent (30,12 %). The analysis of the relative rates of different classes of volatile compounds, revealed the diversity of these compounds in P. mamorensis compared to two cultivars of edible species : P. communis L. et P. pyrifolia. The significant difference in composition in this case could be due to the wild character of P. mamorensis., Moroccan Journal of Chemistry, Vol 4, No 1 (2016)
