Morphological, chemical, and genetic diversity of wild myrtle(Myrtus communis L.) populations in Sicily
Myrtus communis L. İs a shrub widespread in the Mediterranean area. The interest in this species is growing, mainly due to its pharmacological and aromatic properties. The overexploitation of wild populations induced increasing degradation of plant cover with serious risk of loss of genetic diversity. This research explored the morphological, chemical, and genetic diversity of wild myrtle populations in Sicily, with the aim to provide a first characterization of a core collection of 36 accessions from 7 localities for future domestication programs. Amplified fragment length polymorphism fingerprinting generated 152 polymorphic fragments. STRUCTURE analysis identified three genetic clusters …
Sicilian Myrtle Diversity: Evaluation of Leaf Total Phenols Content and Antioxidant Properties
Myrtle (Myrtus communis L.) is an aromatic plant spontaneously growing and increasingly cultivated in Mediterranean area. Recently, interest on myrtle plant is growing due to the pharmacological and antioxidant properties since myrtle leaves are important sources of phenolic and antioxidant compounds with health-promoting effects. Plant genotype is the primary factor affecting antioxidant activity and phenol content. For this reason, a core collection of local selected myrtle accessions from Sicily was evaluated with the aim to identify genotypes with high antioxidant value. Thirty-six myrtle individuals belonging to seven populations were studied for leaf total phenols, tannins and antioxi…
Phenology study of Myrtus communis accessions selected from wild populations of Sicily: preliminary results
Myrtus communis is a Mediterranean shrub widely diffused in Sicily. To promote the cultivation of myrtle, seven wild populations were collected from different areas of Sicily, with the aim to select new candidate cultivars in the frame of a selection program. Considering the berries value in the food industry, many efforts need to be done to cultivate myrtle as alternative to harvest from wild plants. To promote cultivation few important phenologic traits have been recorded in candidate cultivar selections from wild populations in Sicily. This study was performed in a repository field under homogeneous environmental conditions. The vegetation activity of the selected accessions begins in Ja…
