Is the flower fluorescence relevant in biocommunication?
Flower fluorescence has been previously proposed as a potential visual signal to attract pollinators. In this work, this point was addressed by quantitatively measuring the fluorescence quantum yield (Φf) for flowers of Bellis perennis (white, yellow, pink, and purple), Ornithogalum thyrsoides (peta...

It was concluded that the fluorescence emission is negligible compared to the reflected light, even for the most fluorescent samples, and it may not be considered as an optical signal in biocommunication. The work was complemented with the calculation of quantum catches for each studied flower species to describe the visual sensitization of eye photoreceptors. © 2010 Springer-Verlag. 2010 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00281042_v97_n10_p915_Iriel http://hdl.handle.net/20.500.12110/paper_00281042_v97_n10_p915_Iriel |
