Variety traits

Pear flower scent

Pyrus communis L.

The scent of pear flowers is determined by the composition of volatile organic compounds and is a key factor in attracting insect pollinators, which ensures effective fruit set.

In the reference 3 varieties crop European pear, where this is mentioned in the description.

To characterize the scent of Pyrus communis L. flowers, gas chromatography-mass spectrometry methods are used. More than 100 components are identified in the scent composition, with an average concentration of volatile substances of 256 ng per flower per hour.

Out of the total set of compounds, only about 17 components trigger a biologically significant response in honey bees. This trait is not a target for breeding programs focused on fruit marketability or tree resistance, and therefore it is absent from standard state variety testing protocols.
