Early Detection of Damage Conditions in Plants by Delayed Chlorophyll Fluorescence

  • Rolf Blaich

Abstract

A device is described which allows the analysis of delayed chlorophyll fluorescence (luminescence) recorded continuously 20 msec after 50 msec pulses of exciting light. Both qualitative analyses of luminescence images produced by an image intensifier and quantitative measurements using a photomultiplier are possible. Luminescence kinetics are recorded by means of a microcomputer which allows saving of data files, automatic statistic treatment and printout of single or combined curves. The device has been applied to analyse damages caused by herbizides, heat, and freezing.
