Seed germination in the Sicilian subspecies ofDianthus rupicolaBiv. (Caryophyllaceae)

2012

Abstract Five populations belonging to three subspecies of Dianthus rupicola Biv. (D. rupicola subsp. rupicola, D. rupicola subsp. aeolicus, and D. rupicola subsp. lopadusanus) and growing in different geographical areas of Sicily were tested for seed germination at various temperatures. All populations showed high germination rates with an optimum temperature between 15°C and 25°C. Efficient seed germination might contribute significantly to the preservation of these subspecies which are currently exposed to several environmental threats.

Contribution to the identification of Dianthus rupicola (Caryophyllaceae) subspecies using morphological and molecular approaches

2017

The systematic relationships between the five different subspecies actually recognized within Dianthus rupicola (subsp. aeolicus , subsp. bocchorianus , subsp. hermaensis, subsp. lopadusanus and subsp. rupicola ), were assessed by means of morphometric and molecular analysis. Our results highlighted the molecular differences between the five subspecies of D. rupicola and a morphological differentiation of four groups being D. rupicola subsp. aeolicus and D. rupicola subsp. rupicola partly overlapping. At the present state of knowledge, a subspecific status seems the most appropriate for all the recognized subspecies of D. rupicola . The names D. aeolicus , D. bisignanii var. virescens , D. …

Volatile constituents of Dianthus rupicola Biv. from Sicily: activity against microorganisms affecting cellulosic objects.

2014

Dianthus rupicola Biv. (cliffs carnation) is a camephytic, suffruticous, perennial plant growing up to 40 cm high. The plant is widespread in Sicily and neighbouring islands (Egadi, Lampedusa, Lipari) and in some areas of southern Italy. GC and GC-MS analyses of the essential oil distilled from the flowers showed the presence of 66 components. Its composition is characterised by the high content of thymol and carvacrol derivatives. A good antibacterial activity against Bacillus cereus and Bacillussubtilis, both infesting cellulosic historical material, was shown, whereas the antioxidant capacity was determined to be quite poor.
