Trace Detection in Agriculture and Biology

The use of the photoacoustic effect for new applications in agricultural biology is the subject of this chapter. Section 8.1 deals with the photoacoustic detection of ethylene that is produced by specific plant species during senescence and inundation. It was jointly written by the groups of Molecular and Laser Physics (F. Harren, J. Reuss, F. Bijnen) and Experimental Botany (L. Voesenek, C. Blom) from the Catholic University, Nijmegen, and E. Woltering, associated with the Sprenger Institute in Wageningen.
