Paper Abstract

Plants metabolism changes as function of parasitic attacks, nutrients of the ground, environmental condition. This characteristic has been exploited to diagnose possible stresses, for a better control of the production processes to increase the perceived quality in agricultural products, to evaluate the environmental quality and to monitor the effects of human activities on the environment, using plants as the primary sensor. These aims have been pursued through the development of a knowledge based instrument for the early identification of a plant stress state, a hard task to be performed even by a human expert. It is known that information on the photosynthetic apparatus can be obtained from the analysis of the chlorophyll fluorescence. The chosen procedure, known as OJIP test, is based on measurements of the fluorescence dynamic behaviour at 730 nm as it is related with the chlorophyll. The stimulus is generated with an amplitude modulated laser diode, the fluorescence detection is done by means of a photomultiplier to reach a good sensibility. The proposed instrument integrates the knowledge of human experts and laboratory diagnostic techniques for an on-site, non-intrusive and remote analysis.
