Évaluation de l’effet de la quantité et de la qualité de la lumière sur le développement végétatif du manguier : analyses préliminaires et caractérisation initiale du développement végétatif

Abstract : Light is a major environmental factor that modifies plant development and growth. Previously, the effects of light have been well described for the study of plant adaptation to shade. It is also known for some species the important effect of light on the bud break of vegetative and reproductive buds. These studies underline that depending on the species, the effects of the quantity and quality of light can be dissociated or not. The light environment within the mango canopy is well described, and the effects of this environment on bud break identified. However, at this stage, there is no dissociation and evaluation between the effects that are due to the quality of light and those due to the quantity. Effects of the light environment on the vegetative budbreak of mango were first identified under uncontrolled conditions. Then, a second trial was set up to dissociate the effects of the quality of light from those of the quantity on the vegetative budding of the mango tree through different light treatments modifying the quality and/or the quantity of light. During this internship, the analysis of data from a first experimental trial in the canopy of adult mango trees allowed to highlight the relationship between the light environment of the vegetative organ units and bud break. In order to determine if the effects of the quantity and quality of light on vegetative budbreak are dissociated, a second experimental set-up was set up in the field. This second trial consisted in completely modifying the light environment of young mango trees using specific colored filters and describing the budding behavior of mango trees in response to light.
