Interspecific variation of inflorescence scents and insect visitors in Allium (Amaryllidaceae: Allioideae)
2019
Allium is a large monocotyledonous genus, with many species of high economic importance. Knowledge of the pollination biology and the chemical ecology of pollination in this genus is far from being complete. We studied flower visitors of some Allium species in their native habitat and how these interaction partners communicate by olfactory cues. Floral volatiles of five Mediterranean species were investigated by dynamic headspace and thermal desorption-gas chromatography/mass spectrometry (TD-GC/MS). Floral visitors were observed and captured. The physiological activity of scent components in antennae of flower visitors and congeneric species was tested by gas chromatographic/electroantenno…
Phylogenetic Relationship Among Wild and Cultivated Grapevine in Sicily: A Hotspot in the Middle of the Mediterranean Basin
2019
Grapevine (Vitis vinifera ssp. sativa) is a perennial crop especially important for wine and fruit production. The species is highly polymorphic with thousands of different varieties selected by farmers and clonally propagated. However, it is still debated whether grapevine domestication from its wild ancestor (V. vinifera ssp. sylvestris) has been a single event or rather it occurred on multiple occasions during the diffusion of its cultivation across the Mediterranean. Located in the center of the Basin, Sicily is its largest island and has served as a hotspot for all civilizations that have crossed the Mediterranean throughout history. Hundreds of unique grapevine cultivars are still cul…
