Image maker of quantum efficiency of photosynthetic system
- Title:
A method and a device for making images of the quantum efficiency of the photosynthetic system with the purpose of determining the quality of plant material and a method and a device for measuring, classifying and sorting plant material
- Publication number:
WO2004040274
- Description:
The invention relates to a method for determining the quality of plant material, such as for instance whole plants, leaf material, fruits, berries, flowers, flower organs, roots, seeds, bulbs, algae, mosses and tubers of plants, by making chlorophyll fluorescence images, particularly a method wherein a characteristic chlorophyll fluorescence image is calculated from the measured chlorophyll fluorescence images and more particularly a method wherein said characteristic fluorescence image contains information about the quantum efficiency of the photosynthetic activity of photosynthetic system of the plant material. The present invention further relates to a device for measuring the chlorophyll fluorescence images and calculating the image of the quantum efficiency of the photosynthetic activity of the photosynthetic system of the plant material from said chlorophyll fluorescence images. The present invention also relates to a device for sorting and classifying plant material on the basis of the chlorophyll fluorescence images and the image of the quantum efficiency of the photosynthetic activity of the photosynthetic system of the plant material calculated from said chlorophyll fluorescence images.
