Abstract
A device for analyzing plants, by luminous excitation and fluorescence measurement, can be used on site without preparation of the plants. The device evaluates the content of a compound in the skin or epidermis of a plant. The geometry of the device is characterized by a direction of the excitation light rays and a direction of the fluorescence light rays which are non-collinear with each other. The device includes several sets of emitters of different wavelengths, each including several emitters, and makes it possible to measure a plurality of excitation-fluorescence combinations. A method for evaluating and monitoring the development and maturity of a crop, as well as a method for monitoring and controlling plant treatment are also described.
