Vitality and reflectance spectra of living plants: experiments. Aario S, S., O., &., K., H. In 2001.
abstract   bibtex   
The aim of the study was to examine the correlation mechanisms between the vitality of cucumber (Cucumis Sativus) leaves and their reflectance spectra. The reflectance spectra were measured line by line from cucumber leaves with an imaging spectrograph in direct sunlight. For evaluating the water-index and the amount of chlorophylls and carotenoids in the leaf, the ratio of two characteristic reflectances of different wavelengths were calculated for every substance and values were compared to the reference measurements, which were done directly from the leaf. The changes in the distribution of the water-index were also examined during one measurement day, when the plants were desiccated. The water-index and chlorophyll concentration can be very accurately measured from the spectra, but the determination of the amount of carotenoids still needs further investigation. The distributions give us more information than mean values calculated over the leaf.
