Inflorescence scents of Calendula maritima, C. suffruticosa subsp. fulgida, and their hybrid

2018

Premise of research. Hybridization is an important driver of plant evolutionary processes. By attracting the same pollinators to different species, floral scents may be involved in the formation of hybrids and breakdown of species boundaries. In contrast, by attracting a different suite of pollinators to hybrids and their parents, floral scents are believed to contribute to speciation processes initiated by hybridization events. Scents may or may not differ between the hybrids and their parents, but little is known about the scent chemistry of parental species and their hybrids. Methodology. We studied the inflorescence scents of parental Calendula maritima and C. suffruticosa subsp. fulgid…

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…

Inflorescence-visiting insects of a functionally dioecious wild grapevine

2018

The wild grapevine [Vitis vinifera L. subsp. sylvestris (Gmelin) Hegi] is the Eurasian dioecious ancestral form of mostly monoecious domesticated cultivars (Vitis vinifera subsp. vinifera). There are different hypotheses about grapevine pollination, varying from insect to wind pollination to spontaneous self-pollination. The aim of this paper is to update our knowledge on the biology of the wild grapevine by studying the insects visiting their inflorescences. During the fieldworks, floral visitors were observed, captured and identified. The most frequent insects visiting both sexes of wild grapevine were beetles (55%) followed by bees (45%). The present study shows that although in vineyard…
