The sustainability of agro-ecosystems depends on their ability to deliver an entire package multiple ecosystem services, rather than provisioning services alone. New social and ecological dimensions agricultural management must be explored in landscapes, foster this ability. We propose a social–ecological framework for the service-based agro-ecosystems, specified through explicit symmetric representation system, dynamic links between them. It highlights how practices, with effects, could...
Plant diversification using cover crops may promote natural regulation of agricultural pests by supporting alternative prey that enable the increase arthropod predator densities. However, changes in specific composition diet induced cropping are poorly understood. Here, we hypothesized crop can significantly alter predators agroecosystems. The Brachiaria decumbens is increasingly used banana plantations to control weeds and improve physical soil properties. In this paper, a DNA metabarcoding...
Ecophysiological models are increasingly expected to include genetic information via genotype-dependent parameters. These parameters could be considered as quantitative traits and submitted analysis. A pre-existing ecophysiological model of fruit quality was used the distribution genotypic in a second backcross population derived from clone wild peach (Prunus davidiana) commercial nectarine varieties (P. persica (L.) Batsch) analysed. The correlations between two years experimentation were...
The influence of assimilate supply, metabolism and dilution on sugar concentrations in the mesocarp peach (Prunus persica (L.) Batsch) fruit during main stage enlargement was analyzed with SUGAR model Génard Souty (1996).The predicts partitioning carbon into sucrose, sorbitol, glucose fructose fruit.Based measured data model, we determined values for relative rates transformation.These were constant, varied time or growth rate, depending type sugar.Equations derived to describe these...
The fruit is a hierarchically organized organ composed of cells from different tissues. Its quality, defined by traits such as size and composition, the result complex chain biological processes. These processes involve exchanges (transpiration, respiration, photosynthesis, phloem xylem fluxes, ethylene emission) between its environment (atmosphere or plant), tissue differentiation, cell functioning (division, endoreduplication, expansion, metabolic transformations, vacuolar storage). In...
A virtual fruit model simulating seasonal changes in several peach (Prunus persica (L.) Batsch) quality traits during the final growth stage is presented. The considered are size, proportion of total mass consisting flesh, dry matter content flesh and concentrations sucrose, glucose, fructose sorbitol which used to calculate a sweetness index. was developed by adapting integrating three existing process-based models describing growth, fresh sugar accumulation into one complex system. Data...
The soluble sugar concentration of fleshy fruit is a key determinant quality. It affects directly the sweetness fresh fruits and indirectly properties processed products (e.g. alcohol content in wine). Despite considerable divergence among species, accumulation results from complex interplay three main processes, namely import, metabolism, water dilution. Therefore, inter-species comparison would help to identify common and/or species-specific modes regulation accumulation. For this purpose,...
Climate change projections predict warmer and drier conditions. In general, moderate to severe water stress reduce plant vegetative growth leaf photosynthesis. However, reproductive growths show different sensitivities deficit. fruit trees, restrictions may have serious implications not only on tree yield, but also quality, which might be improved. Therefore, it is of paramount importance understand the complex interrelations among physiological processes involved in within-tree carbon...
We modeled the effects of weather and source–sink factors on mango fruit growth. The peach fruit-growth model “Cashoo” was adapted for fruit. accounts main processes growth, i.e., leaf photosynthesis, demand, respiration, storage mobilization stem reserves. Simulations three successive years various leaf-to-fruit ratio treatments showed good agreement with observed growth data. under different climatic conditions, especially contrasting temperature radiation, values initial dry mass ratio,...
Investigations on “natural” cuticular cracks were conducted nectarine fruit [ Prunus persica (L.) Batsch var. nucipersica (Suckow) C.K. Schneid.]. A method for quantifying the crack surface area a whole basis was proposed. By using stratified sampling design, spatial distribution of over three regions (stylar end, peduncle, and cheek), their morphology, estimation total proportion studied. These features examined during development in response to several growing conditions corresponding...
Changes in elastic and plastic components of mango (Mangifera indica L. cv 'Cogshall') fruit growth were analyzed with a model over time response to various assimilate supplies. The is based on water relations (water potential osmotic turgor pressures) at the level. Variation was modeled as function modulus variation pressure. using Lockhart (1965) equation. In this model, parameters (yield threshold pressure cell wall extensibility) varied during growth. Outputs diurnal seasonal growth,...
