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.

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.

Para esto se consideró una finca con ... -
Estado sanitario en racimos en var. Malbec después de varios años de riego deficitario regulado y regulación de la carga de cultivos
Rodriguez Romera, Mariela Carmen; Gonzalez Erbin, Omar Adrian; Diaz, Mariano Emanuel; Morales, Andres Antonio; Perez Peña, Jorge Esteban (Asociación Argentina de Fitopatólogos (AAF), 2024)El riego deficitario regulado (RDI) y el raleo de racimos son prácticas vitícolas globales. Sin embargo, existe un conocimiento limitado sobre sus efectos combinados sobre las enfermedades en los racimos. Por esta razón ... -
High temperature during the budswell phase of grapevines increases shoot water transport capacity
Galat Giorgi, Mirta Eugenia; Keller, Markus; Sadras, Victor Oscar; Roig Junent, Fidel Alejandro; Perez Peña, Jorge Esteban (Elsevier, 2020-09)Knowledge about heat acclimation in perennial plants is limited. Our hypotheses were (i) that high temperature during budswell before budbreak elicits acclimation in grapevines that is mediated by greater water transport ... -
Identity and parentage of some South American grapevine cultivars present in Argentina
Aliquo, Gustavo; Torres, Maria Del Rocio; Lacombe, Thierry; Boursiquot, Jean-Michel; Laucou, Valerie; Gualpa, Jose Luis; Fanzone, Martín Leandro; Sari, Santiago Eduardo; Perez Peña, Jorge Esteban; Prieto, Jorge Alejandro (2017)Background and Aims: Based on 19 nuclear simple sequence repeat markers and parental analysis, we aimed to identify and propose the pedigree of different accessions held at the Estación Experimental Agropecuaria Mendoza ... -
Influencia de la Malla Antigranizo sobre el Microclima de la Vid (Vitis Vinífera L.) Var. Merlot

Interactive effects of high temperature and water deficit on Malbec grapevines
Galat Giorgi, Mirta Eugenia; Sadras, Victor Oscar; Keller, Markus; Perez Peña, Jorge Esteban (Wiley, 2019-06-26)Background and Aims: Studies of the interactive effects of drought and high temperature on the physiological responses of grapevines (Vitis spp.) are scarce. We tested whether well‐watered, potted vines were able to avoid ... -
Late pruning modifies leaf to fruit ratio and shifts maturity period, affecting berry and wine composition in Vitis vinífera L. cv. ‘Malbec’ in Mendoza, Argentina
Bustos Morgani, Marianela; Fanzone, Martín Leandro; Perez Peña, Jorge Esteban; Sari, Santiago Eduardo; Gallo, Agustina Eugenia; Gómez Tournier, Mariana Belén; Prieto, Jorge Alejandro (Elsevier, 2023-04)Higher temperatures in recent years have advanced berry ripening and harvest date, decoupling berry sugar accumulation of anthocyanins final concentration and therefore reducing wine potential color. Late pruning is proposed ... -
