Device Plant of field analysis, monitoring process, or mapping of the state or the Evolution of a culture and method of administration for treatment of plants

The present invention relates to a plant analysis device, by light excitation and measurement of fluorescence, for field use without preparation vegetaux.Elle further relates to a processing unit of the content of a compound in the skin or epidermis of a vegetal.A from the use of such apparatus, the invention also relates to a method for evaluating and monitoring the development and maturation of a culture, and a method control and processing vegetaux.La steering geometry of the device is characterized by a direction of the excitation light rays and a direction of the light ray fluorescence noncolinear between elles.L'appareil includes several sets of transmitters of different wavelengths, each comprising a plurality of transmitters, and can measure a plurality of combinations excitation fluorescence.
