Discrimination between 15 weed species was done using chlorophyll fluorescence image analysis. The fluorescence parameters F₀ (minimum fluorescence) and F_p (peak fluorescence shortly after the induction of the Kautsky-Effect) were used to differentiate between mono- and dicotyledonous plants and within the grouped species at different growth stages. Weed species used in the experiment were sown in a greenhouse under controlled conditions and collected from agricultural fields. Fluorescence measurements were done in the cotyledonous and in the 8-10 leaves growth stage. It is shown that simple fluorescence parameters (F_o and F_p) can be used for discrimination of weed species. This suggests that chlorophyll fluorescence measurements could potentially be used in precision farming to identify weeds.
