Doctoral thesis, Universitat de Lleida, 2015. http://hdl.handle.net/10803/386572.
Texte intégralEl principal objetivo de la tesis fue evaluar los determinantes fisiológicos del rendimiento de un cultivar de trigo tradicional y uno moderno en respuesta a diferentes disponibilidades de agua y nitrógeno en condiciones mediterráneas. Se puede concluir que el cultivar tradicional no superó claramente en rendimiento al moderno bajo condiciones más estresantes, ni el cultivar moderno superó a su contraparte tradicional cuando las condiciones fueron más favorables. En relación a los dos componentes numéricos del rendimiento, el número de granos por unidad de superficie fue el principal componente explicando su variación y el peso del grano fue limitado por sumidero durante el llenado de grano. El uso del nitrógeno y el agua y sus eficiencias estuvieron relacionadas con las variaciones del rendimiento para ambos cultivares. La absorción de nitrógeno ocurrió principalmente durante pre-antesis, mientras que la concentración de nitrógeno en grano estuvo generada mayormente por translocación. El cultivar moderno presentó un sistema radicular mayor que el tradicional. Sin embargo, esta superioridad no se tradujo en diferencias consistentes en rendimiento o eficiencia en el uso de recursos.
The main objective of the thesis was to assess the physiological grain yield determinants of a traditional and a modern wheat cultivar in response to different water and nitrogen availabilities under Mediterranean conditions. It can be concluded that the traditional cultivar did not consistently outyield the modern one under more stressful conditions, nor did the modern cultivar outyield its older counterpart whenever the conditions were less stressful. Concerning the two major numerical components of grain yield, grain number per unit land area was the main component explaining its variation and grain weight was sink-limited during grain filling. N and water use and their efficiencies were related to variations in grain yield for both cultivars. N uptake occurred mainly along pre-anthesis, while grain N concentration was generated chiefly by translocation. The modern cultivar presented a larger root system than the traditional one. Nevertheless this superiority did not translate in consistent differences in grain yield or resource use efficiencies.

Texte intégralPlantations of fast-growing species (e.g. poplars, willows, eucalyptus) are widely used for biomass supply. However, these plantations are often monospecific systems and are generally very resource demanding. This is particularly the case for plantations of species belonging to the Populus genus, which can be grown under intensive cultivation conditions, and which use large quantities of water and nitrogen to produce large volumes of biomass. In this context, mixed forest or agroforestry plantations appear as an interesting alternative to monocultures. Indeed, they can produce more by using more efficiently the resources necessary for the growth of the different components of the mixture by playing on the complementarity between the species. The introduction of nitrogen-fixing species in these mixtures can also be an additional asset to reduce the need for synthetic nitrogen inputs.In any plantation, forest or agroforestry, intraspecific interactions (individuals of the same species) or interspecific interactions (between individuals of two different species) can be negative, positive, or neutral. To date, the interactions between species that determine whether a given mixture will be more productive than the corresponding monocultures are still poorly understood and studies of their impact on resource-use efficiency are scarce. The overall objective of the PhD work was to evaluate the impact of several species mixtures, both forest and agroforestry, on tree growth performance through effects on functional (resource-use efficiencies), structural (crown architecture) and phenological (spring and fall bud and leaf phenology) determinants. The main hypothesis was that thanks to symbiotic nitrogen fixation and complementarity between species, trees in mixtures would be more productive and use resources more efficiently than in monoculture.This objective was pursued on an instrumented plantation on the La Bouzule site (54), installed in spring 2014, composed of mixtures of woody (poplars and alders) and herbaceous (legumes, graminoids) species, as well as their respective monocultures. The functioning of three types of mixtures including nitrogen-fixing species (poplars/alfalfa - clover succession; poplars/alders; alders/cereal - temporary grassland succession) was compared with monocultures of the two woody species. The originality of the work lies on the combination of the study of processes occurring at the organ and tree scales to describe the interaction processes between species and the overall performance of the different types of mixtures, compared to their respective monocultures.Species interactions in a plantation are not static but change as the stand develops. The nature of the interactions between poplars and legumes in the agroforestry plot evolved from a predominant competition at the beginning of the plantation to facilitation through soil nitrogen enrichment. The growth performances of the poplars were increased compared to the monoculture, associated with a higher water-use efficiency than in monoculture and a reduction of competition between the canopies allowing a better interception of light in agroforestry. In contrast, higher water-use efficiency of poplars associated with alder than in monoculture was not associated with better growth performances of both species compared to their respective monocultures. Overall, alder was only slightly affected by the mixtures

Texte intégralCompared to monocultures, agroforestry systems (AFS) are expected to provide enhanced resource-use efficiency and larger ecosystem services. However, due to the complexity of the interactions occurring in AFS, it is challenging to quantify and decompose the effects of shade trees on the main crop net primary productivity (NPP). Few process-based models are able to analyze the interactions between crop and shade trees for carbon and water. Interactions for light, water and energy occurring between tree and crops might have counterintuitive effects on photosynthesis, light use efficiency (LUE), transpiration efficiency and microclimate. We showed that a 3D process-based model, MAESPA, was able to quantitatively describe the spatial variability of those processes from the plant to the plot, and from hourly to yearly timescales. MAESPA simulated satisfactorily light interception in a 2-layer heterogeneous coffee AFS. It was used to produce powerful explanatory variables in AFS experiments and to analyze the determinants of coffee plant NPP. LUE displayed a 2-fold increase for shaded coffee plants totally compensating the expected decrease of local irradiance interception, and coffee plant ANPP was the same below shade trees or in the open. MAESPA also simulated satisfactorily carbon exchange at whole plant and plot scales, when compared to gas exchange records in a whole-plant chamber, or with eddy-covariance records above the canopy. We used MAESPA to simulate the spatial variability of photosynthesis and LUE. Overall, MAESPA proved to be a relevant model to quantify spatial interactions. The next very relevant development would be to couple it to a model of carbon allocation among organs in the coffee plants
