Carbon balance in grapevine under a changing climate
Medrano Gil, Hipolito; Perez Peña, Jorge Esteban; Prieto, Jorge Alejandro; Tomás Mir, Magdalena; Franck, Nicolás; Escalona Lorenzo, José Mariano (2016)The measurement of the carbon balances is necessary to evaluate the contribution of different biomes to carbon sequestration and therefore to mitigate the global climate change effects. Carbon balance of grapevine is of ... -
Changes in leaf stomatal conductance, petiole hydraulics and vessel morphology in grapevine (Vitis vinífera cv.Chasselas) under different light and irrigation regimes

In this study, we assessed the combined effects of radiation ... -
Drought will not leave your glass empty : low risk of hydraulic failure revealed by long-term drought observations in world’s top wine regions
Charrier, Guillaume; Delzon, Sylvain; Domec, Jean Christophe; Zhang, Li; Delmas, Chloe E. L.; Merlin, Isabelle; Corso, Deborah; King, Andrew; Ojeda, Hernan; Ollat, Nathalie; Prieto, Jorge Alejandro; Scholach, Thibaut; Skinner, Paul; Leeuwen, Cornelis van; Gambetta, Gregory A. (2018)Grapevines are crops of global economic importance that will face increasing drought stress because many varieties are described as highly sensitive to hydraulic failure as frequency and intensity of summer drought increase. ... -
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 ... -
Grapevine morphological shade acclimation is mediated by light quality whereas hydraulic shade acclimation is mediated by light intensity
Gonzalez, Carina Veronica; Prieto, Jorge Alejandro; Mazza, Carlos Alberto; Jeréz, Damián Nicolás; Biruk, Lucía N.; Jofre, María Florencia; Giordano, Carla Valeria (Elsevier, 2021-06)Plants acclimate to shade by sensing light signals such as low photosynthetic active radiation (PAR), low blue light (BL) levels and low red-to-far red ratios (R:FR) trough plant photoreceptors cross talk. We previously ... -
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 ... -
