Abstract
The photon emission (ultraweak photon emission and delayed luminescenc e) of duckweeds (Spirodela polyrrhiza) and 1-2 year old tree seedlings (Picea abies, Abies alba and Fagus silvatica) was investigated by mea ns of a single photon counting equipment. The decay kinetics of DL, th e temperature dependence of UPE, and the anaerobic phase-induced kinet ics of UPE were measured under/after treatment with ozone and UV-radia tion. The results suggest that more consideration be given to photon e mission as an indicator of stress-induced changes in plants.
