A functional–structural plant model that simulates whole- canopy gas exchange of grapevine plants (Vitis vinifera L.) under different training systems Prieto, Jorge Alejandro; Louarn, Gaëtan; Perez Peña, Jorge Esteban; Ojeda, Hernan; Simonneau, Thierry; Lebon, Eric (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.) Prieto, Jorge Alejandro; Louarn, Gaëtan; Perez Peña, Jorge Esteban; Ojeda, Hernan; Simonneau, Thierry; Lebon, Eric (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 ...
An empirical model that uses light attenuation and plant nitrogen status to predict within-canopy N distribution and upscale photosynthesis from leaf to whole canopy Louarn, Gaëtan; Frak, Ela; Zaka, Serge; Prieto, Jorge Alejandro; Lebon, Eric (2015-10-03)Modelling the spatial and temporal distribution of leaf nitrogen (N) is central to specify photosynthetic parameters and simulate canopy photosynthesis. Leaf photosynthetic parameters depend on both local light availability and ...
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) Albasha, Rami; Fournier, Christian; Pradal, Christophe; Chelle, Michael; Prieto, Jorge Alejandro; Louarn, Gaëtan; Simonneau, Thierry; Lebon, Eric (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 ...
Stomatal behavior of different grapevine cultivars in response to soil water status and air water vapor pressure deficit Prieto, Jorge Alejandro; Lebon, Eric; Ojeda, Hernán (International Viticulture and Enology Society (IVES), 2010-03)Aims: Genetic variability in grapevine cultivars may influence their strategy to cope with drought through stomatal regulation of transpiration rate. The aim of the present study was to evaluate the stomatal sensitivity ...
