Application of a SUGAR model to analyse sugar accumulation in peach cultivars that differ in glucose–fructose ratio Inra
Wu, B.H.; Quilot-Turion, B.; Génard, M.; Li, S.H.; Zhao, J.B.; Yang, J.; Wang, Y.Q..
A SUGAR model, which was established to predict the partitioning of carbon into sucrose, glucose, fructose and sorbitol in fruit mesocarp of peach cultivars (Prunus persica (L.) Batch) with normal glucose: fructose ratio (G:F) of 0·8–1·5, was evaluated and extended for peach cultivars with a high G:F ratio of 1·5–7·8. The extended model (SUGARb) is more generic and assumes a high G:F ratio to be due to preferential transformation of sorbitol into glucose, preferential utilization of fructose or preferential conversion of fructose into glucose. The simulated seasonal variations in sugars via the SUGARb-model-matched experimental data for three normal and three high G:F cultivars well, and accurately exhibited G:F ratio characteristics. The relative rates of...

Combining ecophysiological modelling and quantitative trait locus analysis to identify key elementary processes underlying tomato fruit sugar concentration Inra
Prudent, M.; Lecomte, A.; Bouchet, J.P.; Bertin, N.; Causse, M.; Génard, M..
A mechanistic model predicting the accumulation of tomato fruit sugars was developed in order (i) to dissect the relative influence of three underlying processes: assimilate supply (S), metabolic transformation of sugars into other compounds (M), and dilution by water uptake (D); and (ii) to estimate the genetic variability of S, M, and D. The latter was estimated in a population of 20 introgression lines derived from the introgression of a wild tomato species (Solanum chmielewskii) into S. lycopersicum, grown under two contrasted fruit load conditions. Low load systematically decreased D in the whole population, while S and M were targets of genotype×fruit load interactions. The sugar concentration positively correlated to S and D when the variation was...

Effects of different irrigation regimes applied during the final stage of rapid growth on an early maturing peach cultivar Inra
Mercier, V.; Bussi, C.; Lescourret, F.; Génard, M..
Different irrigation regimes were performed on container-grown early-season peach trees (cv. Alexandra) during stage III of fruit growth. In the first experiment, three water treatments were applied: T1, control irrigation; T2, light water restriction; T3, high water restriction. In the second experiment, T4, a light water restriction, was compared to T5, the same total amount of water as T4 but with alternating periods of water withholding and subsequent re-irrigation. Compared to T1 and T2, leaf photosynthesis was limited under T3. Fruit yield and quality did not differ between T1 and T2, while fruit yield, average weight and percentage in the higher commercial grade decreased and total soluble solids (TSS) increased under T3, compared to T1 and T2....

Effets d'une contrainte hydrique sur le flux pédonculaire massique et la croissance de la pêche Inra
Huguet, J.G.; Génard, M..
L’objectif de cette étude était d’établir, pendant la dernière phase de croissance active de la pêche (Prunus persica (L) Batsch cv Dixired), l’influence des conditions d’alimentation hydrique sur la croissance des fruits. Des pêchers sont cultivés en pots, selon 2 régimes de disponibilité en eau (avec ou sans restriction) et les microvariations du diamètre des troncs ont été enregistrées pour servir d’indicateur de la contrainte. Pour chaque traitement, l’évolution du diamètre de quelques fruits a été suivie par micromorphométrie. Les diamètres de toutes les autres pêches ont été suivis par mesures manuelles. La transpiration propre des fruits a été évaluée sur des fruits cueillis, en mesurant soit leurs pertes de masse, soit les variations...

Fluctuations in sugar content are not determinant in explaining variations in vitamin C in tomato fruit Inra
Massot, C.; Génard, M.; Stevens, R.; Gautier, H..
The present study aimed to clarify the relationship between sugars and vitamin C in fruit. The objective was to determine whether vitamin C content was regulated by sugar content due to the role of sugar as a precursor for vitamin C. During summer, maximal content in sugar and vitamin C were found in both genotypes tested Solanum lycopersicon ‘Cervil’ and ‘Levovil’. During autumn, fruit pruning increased fruit size and hexose content but fruit vitamin C content did not increase. Therefore sugar substrate was not limiting for vitamin C synthesis during autumn. We demonstrated for two cultivars, ‘Cervil’ and ‘Levovil’, with different sugar accumulation profiles during ripening, that sugar content was not determinant in the regulation of vitamin C content....

How does tomato quality (sugar, acid, and nutritional quality) vary with ripening stage, temperature, and irradiance Inra
Gautier, H.; Diakou-Verdin, V.; Bénard, C.; Reich, M.; Buret, M.; Bourgaud, F.; Poëssel, J.L.; Caris-Veyrat, C.; Génard, M..
The objective of this study was to understand the respective impact of ripening stage, temperature, and irradiance on seasonal variations of tomato fruit quality. During ripening, concentrations in reducing sugars, carotenes, ascorbate, rutin, and caffeic acid derivates increased, whereas those in titratable acidity, chlorophylls, and chlorogenic acid content decreased. Fruit temperature and irradiance affected final fruit composition. Sugars and acids (linked to fruit gustative quality) were not considerably modified, but secondary metabolites with antioxidant properties were very sensitive to fruit environment. Increased fruit irradiance enhanced ascorbate, lycopene, β-carotene, rutin, and caffeic acid derivate concentrations and the disappearance of...

Is competition between mesocarp cells of peach fruits affected by the percentage of wild species (Prunus davidiana) genome Inra
Quilot-Turion, B.; Génard, M..
The number of cells and the mean cell volume in the mesocarps of fruits from peach genotypes with different percentages of the genome of Prunus davidiana, a wild, related, species, were evaluated. The mesocarp mass varied greatly between the four groups of genotypes. The mean cell volume and the number of cells were negatively correlated within each group. This correlation can be interpreted as a relationship of competition between cells. In order to describe the type of competition in the different groups, we tried to adjust a model of competition for resources proposed by Lescourret and Génard (Ecoscience 10:334–341, 2003). To estimate the values of the three parameters of the model for the different groups, we applied model selection. Within nested...

L'intégration, art ou science ? Inra
Chevassus-Au-Louis, B.; Génard, M.; Glaszmann, J.C.; Habib, R.; Houllier, F.; Lancelot, R.; Malézieux, E.; Muchnik, J..
Nous défendons dans cette étude l'idée que l'intégration doit jouer à l'avenir un rôle central dans les recherches sur l'agriculture, l'alimentation et la gestion des territoires ruraux. En partant de définitions de l'intégration fondées sur l'importance d'un inventaire exhaustif des composantes d'un système, sur l'existence d'interactions nombreuses et complexes entre ces composantes et sur l'émergence de propriétés originales liées à ces interactions, nous soulignons tout d'abord les limites des approches «réductionnistes», qui n'étudient, et de manière séparée, que les composantes considérées comme «majeures» d'un système agricole ou agroalimentaire. Nous analysons ensuite les raisons qui poussent aujourd'hui à renforcer cette approche, en distinguant...

Model-assisted analysis of tomato fruit growth in relation to carbon and water fluxes Inra
Liu, H.F.; Génard, M.; Guichard, S.; Bertin, N..
This work proposed a model of tomato growth adapted from the Fishman and Genard model developed to predict carbon and water accumulation in peach fruit. The main adaptations relied on the literature on tomato and mainly concerned: (i) the decrease in cell wall extensibility coefficient during fruit development; (ii) the increase in the membrane reflection coefficient to solute from 0 to 1, which accounted for the switch from symplasmic to apoplasmic phloem unloading, and (iii) the negative influence of the initial fruit weight on the maximum rate of active carbon uptake based on the assumption of higher competition for carbon among cells in large fruits containing more cells. A sensitivity analysis was performed and the model was calibrated and evaluated...

Water deficits uncouple growth from photosynthesis, increase C content, and modify the relationships between C and growth in sink organs Inra
Muller, B.; Pantin, F.; Génard, M.; Turc, O.; Freixes, S.; Piques, M.; Gibon, Y..
In plants, carbon (C) molecules provide building blocks for biomass production, fuel for energy, and exert signalling roles to shape development and metabolism. Accordingly, plant growth is well correlated with light interception and energy conversion through photosynthesis. Because water deficits close stomata and thus reduce C entry, it has been hypothesised that droughted plants are under C starvation and their growth under C limitation. In this review, these points are questioned by combining literature review with experimental and modelling illustrations in various plant organs and species. First, converging evidence is gathered from the literature that water deficit generally increases C concentration in plant organs. The hypothesis is raised that...
