All terrestrial plants transpire water, but where exactly does that water come from within the soil? This seemingly simple research question has been the subject of studies for many years. Stable isotopes of oxygen and hydrogen “tracers” have proven useful for shedding light on patterns of plant water use. However, the use of such tracers alone limits our understanding of patterns of source uptake and the mechanisms behind tracer observations. To go beyond this black box approach, we integrated measurements of stable isotope composition in xylem and soil water.
Variations of tomato fruit weight and composition throughout the cycle of production make the management of fruit yield and quality complex. These variations are linked to the fluctuation of water and carbon available for fruit growth and depend on the genotype and environmental conditions. Some structural functional plant models can predict the concentration of water and carbon in the plant architecture and the consequences on fruit growth. Obtaining measures of sap fluxes in situ is difficult.

My goal is to understand how irrigation affects fruit and wine production in the Douro Region, one of the oldest production regions of the world.
During the last several decades, environmental pollution problems caused by the extensive use of chemical herbicides have encouraged the introduction of integrated crop production. A further boost to these methods has been provided by market demand, where organic or “biologique” products are increasingly requested by consumers. In vineyards and orchards, one of the most widely used methods of non-chemical weed control is through the mechanical action of agricultural implements.
Controlled atmosphere or modified atmosphere packaging are clean and potentially effective techniques to extend the storage life of dragon fruit (Hylocereus undatus). Application of these techniques requires thorough knowledge about the fruit respiration rate. To this end, this study aims to model the respiration rate as a function of O2 and CO2 level, and temperature, using Michaelis-Menten kinetics and Arrhenius’ law. Dragon fruit were incubated in closed containers with different initial O2 concentrations (5-21%), initial CO2 concentrations (0-10%), and temperatures (2-35°C).
