| abstract |
The subject of the invention is the use of a mobile light exposure device (1) that delivers light pulses to a plant material (2), comprising a first emission module (3) for emitting one or more light pulses, comprising at least one light treatment panel; a second adjusting and/or switching module (6), remote from or on the device, for adjusting and/or switching on the optical power density of the treatment panel and optionally the temperature of said panel; and a locomotive means (4) for moving the device; for preventing and/or attenuating the effects on the plant material which are associated with abiotic stresses, preferably stresses associated with edaphic, climatic and/or chemical factors. |
