peer reviewedIntroduction. La gestion optimale de la fertilisation azotée des cultures nécessite l’utilisation de méthodes qui permettent d’évaluer rapidement et avec précision le statut azoté de la biomasse aérienne en cours de saison. C’est le cas des mesures optiques sur le végétal et parmi celles-ci, les approches basées sur la mesure de la fluorescence chlorophyllienne (ChlF) des feuilles occupent une place intéressante. Les potentialités de la ChlF sont étudiées depuis plusieurs années pour détecter et quantifier différents stress biotiques et abiotiques des plantes et la ChlF peut s’envisager pour l’évaluation du statut azoté. Ces approches permettent a priori de pallier certaines limitations des méthodes souvent utilisées pour ...
