Ozone degrades floral scent and reduces pollinator attraction to flowers

In this work we analyzed the degradation of floral scent volatiles from Brassica nigra by reaction with ozone along a distance gradient and the consequences for pollinator attraction. - For this purpose we used a reaction system comprising three reaction tubes in which we conducted measurements of f...
