Estimating the term…
A method of monitoring health in chlorophyll containing matter comprises exposing the matter to a light source to cause chlorophyll to fluoresce and emit a fluorescence signal. Any changes in a parameter indicative of changes in the intensity of the fluorescence signal are detected and compared with a predetermined threshold. A change which exceeds the predetermined threshold is interpreted as a transition of the level of stress in the chlorophyll containing matter. An apparatus for monitoring health in chlorophyll containing matter is also provided and comprises a light source for causing chlorophyll in the matter to fluoresce, a detector for detecting the intensity the fluorescent signal, means for measuring changes in a parameter indicative of changes in the intensity of the fluorescent signal and a detector to detect an increase in the change of the parameter above a predetermined threshold.
A method of detecting the onset of stress in chlorophyll containing matter, said chlorophyll containing matter being exposed to a stress inducing condition, the method comprising:
A method as claimed in claim l, comprising measuring the intensity of the fluorescence signal at each of a plurality of different light levels, and deriving said parameter based on said plurality of fluorescence signal intensity measurements.
An apparatus for detecting the onset of stress in chlorophyll containing matter, comprising:
A method of detecting the recovery from stress in chlorophyll containing matter, said chlorophyll containing matter being exposed to a stress affecting condition, the method comprising:
An apparatus for detecting the recovery from stress in chlorophyll containing matter comprising:
