description

EASPEGESTAD INRA; La modélisation, et plus particulièrement le modèle de prédiction de flore adventice FLORSYS, nécessite l’acquisition constante de données sur la croissance et la plasticité morphologique d’espèces cultivées et d’adventices. Nous avons mis au point une méthodologie basée sur de l’expérimentation en parcelles jardinées pour quantifier la croissance et la plasticité morphologique des espèces dans des conditions contrastées de lumière. Les données sont obtenues par des mesures de surfaces foliaires, de hauteurs et envergures des plantes, des pesées de biomasse, et par analyse de photographies via les logiciels Matlab et ImageJ. Nous montrerons les résultats pour quelques espèces adventices.
