Elaboration de la qualité du fruit : composition en métabolites primaires et secondaires

Abstract : Improving the quality of products quality is an economic, public health and scientific issue. How the fruit composition is elaborated is a research question for some INRA research teams working on quality. The objective of this paper is to present recent knowledge on this topic using some examples from our results on tomato. The fruit growth results from the multiplication of cells and their growth in size and volume, these two processes being strongly mediated by the number of fruits growing on the plant. Molecules very different in nature and concentrations accumulate or are transported or used in the fruit during fruit growth or maturation of tissues, determining their composition and quality. The composition in sugars, acids, vitamin C and secondary metabolites is determined by the stage of fruit development, the environmental parameters (temperature, radiation) and culture management (size, fruit load, N fertilization, genotype). A model "virtual fruit” is presented; it is able to simulate fruit growth, degree of maturity and change in dry matter and compounds, under the influence of factors, such as water availability.
