Fragrance chemistry, nocturnal rhythms and pollination “syndromes” in Nicotiana

Phytochemistry, 2003
GC-MS analyses of nocturnal and diurnal floral volatiles from nine tobacco species (Nicotiana; Solanaceae) resulted in the identification of 125 volatiles, including mono- and sesquiterpenoids, benzenoid and aliphatic alcohols, aldehydes and esters. Fragrance chemistry was species-specific during nocturnal emissions, whereas odors emitted diurnally ...

Why Are Flowers Different? Pollination Syndromes—The Theory

2007
AbstractIt is clear from a merely cursory glance around any garden in the summer months that flowers come in an enormous variety of sizes, shapes, colours, and scents. The book now focusses on the differences between flowers, as opposed to the molecular similarities that unite them. This chapter begins by considering the different ways that flowers can

3-D pollination syndromes in Aquilegia

2023
Flowers of the genus Aquilegia are pentamerous and have two petaloid perianth whorls, of which the inner one is spurred; nevertheless, their morphology is highly diverse. In Asia and Europe pollinators are mostly bumblebees and bees, while in North America shifts to hummingbird and hawkmoth pollination have occurred.

Pollination syndromes and pollinator shifts can be explained by climatic and elevational gradients

Pollination syndromes are defined as suites of floral traits, which have evolved repeatedly across angiosperms in adaptation to distinct functional pollinator groups. The large, pantropically distributed family Melastomataceae is dominated by buzz-bee pollination (95.5 %), where pollen is released from tubular, poricidal anthers through vibrations.
