Ozone- and UV-stress detected by photon emission of plants
Published online by Cambridge University Press: 05 December 2011
Synopsis
The photon emission (ultraweak photon emission and delayed luminescence) of duckweeds (Spirodela polyrrhiza) and 1–2 year old tree seedlings (Picea abies, Abies alba and Fagus silvatica) was investigated by means of a single photon counting equipment. The decay kinetics of DL, the temperature dependence of UPE, and the anaerobic phase-induced kinetics of UPE were measured under/after treatment with ozone and UV-radiation. The results suggest that more consideration be given to photon emission as an indicator of stress-induced changes in plants.
