A comparison of methods for excluding light from stems to evaluate stem photosynthesis
(Wiley, 2023-09)Premise: A comparison of methods using different materials to exclude light from stems to prevent stem CO2 exchange (i.e., photosynthesis), without affecting stem conductance to water vapor, surface temperature, and relative ... -
A functional–structural plant model that simulates whole- canopy gas exchange of grapevine plants (Vitis vinifera L.) under different training systems
(Oxford University Press, 2020-09)Background and Aims: Scaling from single-leaf to whole-canopy photosynthesis faces several complexities related to variations in light interception and leaf properties. To evaluate the impact of canopy strucuture on gas ... -
A leaf gas exchange model that accounts for intra‐canopy variability by considering leaf nitrogen content and local acclimation to radiation in grapevine (Vitis vinifera L.)
(Wiley, 2012-07)Understanding the distribution of gas exchange within a plant is a prerequisite for scaling up from leaves to canopies. We evaluated whether leaf traits were reliable predictors of the effects of leaf ageing and leaf ... -
Coberturas vegetales en viñedos bajo riego localizado, respuesta fisiológica de especies herbáceas nativas a diferentes ambientes
(Escuela para Graduados, Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2015)En Mendoza, Argentina es imprescindible regar los cultivos debido a las escasas precipitaciones y a la elevada evapotranspiración. El uso de coberturas vegetales es una herramienta sostenible con múltiples beneficios ... -
Comparison of field measurement methods of nitrous oxide soil emissions: from the chamber to the vial
(Sociedade Brasileira de Ciencia do Solo, 2020-07-16)Nitrous oxide (N2O) is a greenhouse gas that contributes substantially to global climate change. The N2O soil emissions have a large uncertainty because of its low atmospheric concentration levels and enormous spatial and ... -
Especies herbáceas nativas : aportes para su cultivo como coberturas vegetales en viñedos bajo riego en Mendoza : estudios de intercambio gaseoso, eficiencia hídrica y potencial alelopático de lixiviados
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2013)Los cultivos de cobertura son utilizados dentro del manejo de suelo en viñedos como una herramienta ambientalmente sostenible con diversos objetivos. Mientras que las coberturas verdes contribuyen al secuestro y almacenamiento ... -
Glutathione, a key compound for As accumulation and tolerance in soybean plants treated with AsV and AsIII
(Elsevier, 2019-06)Despite soybean (Glycine max L.) is often cultivated in areas contaminated with arsenic (As) which causes deleterious effects on its growth, little is known about tolerance mechanisms in response to As exposure. In particular, ... -
HydroShoot: a functional-structural plant model for simulating hydraulic structure, gas and energy exchange dynamics of complex plant canopies under water deficit—application to grapevine (Vitis vinifera)
(Oxford Academic Press, 2019-06)This paper presents HydroShoot, a leaf-based functional-structural plant model (FSPM) that simulates gas exchange rates of complex plant canopies under water deficit conditions. HydroShoot is built assuming that simulating ... -
Syrah and Grenache (Vitis vinifera) revealed different strategies to cope with high temperature
(Australian Society of Viticulture and Oenology, 2022-03-02)Background and Aims: Global warming will threaten vineyard sustainability in warm and arid regions. Therefore, increasing water use efficiency (WUE) is essential for long-term viticulture sustainability. Nevertheless, ... -
Whole plant open chamber to measure gas exchange on herbaceous plant
(2016)Much of our understanding about CO2 and H2O gas exchange in plants has been gained from studies at leaf level. Extrapolation of results to whole plant is difficult and not always accurate. In order to overcome this limitation, ...
