HS-SPME-GC-MS determination of the scent of taxa (fam. Orchidaceae) from Basilicata (Southern Italy).

The scent of species has been analyzed by using HS-SPME-GC-MS. The sample was collected in Basilicata (Southern Italy). Every species showed a different composition of the scent in the analyses we performed.

The scent of orchids from Basilicata (Southern Italy).

The scent of species has been performed by using solid-phase microextraction- gas chromatography- mass spectrometry (SPME-GC-MS). The scent of showed the presence of 9-tricosene, 1-nonadecanol and heinecosane. The analysis of the scent of gave α-ionone as the main component.

Pollination features and floral volatiles of Gymnospermium scipetarum (Berberidaceae).

The discovery of few isolated populations of Gymnospermium scipetarum (since now considered as an amphi-Adriatic endemic) in the S-Apennines prompted to investigate, also for conservation purposes, some aspects of its reproductive biology. We aim: (1) to determine if insects play an important role in pollination; (2) to describe the pollinator community; (3) to detect floral scent composition. Experiments of insect exclusion were carried out in the field using 24 flowering individuals: one raceme was capped whereas the nearest one was used as control to ascertain differences in seed set.
