La aplicación de nitrógeno en otoño retrasa la senescencia foliar en manzano (Malus domestica Borkh)
De Angelis, Veronica; Sanchez, Enrique Eduardo; Tognetti, Jorge Alberto (Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-04)La prolongación de la duración de la vida de las hojas de frutales en otoño es deseable ya que contribuye a mejorar la disponibilidad de reservas para el ciclo siguiente. El objetivo de este trabajo fue evaluar el efecto ... -
Low temperature differentially affects tillering in spring and winter wheat in association with changes in plant carbon status
Lorenzo, Maximo; Assuero, Silvia Graciela; Tognetti, Jorge Alberto (Wiley, 2015-03)The higher tillering potential of winter wheat cultivars as compared to spring ones has been attributed to an earlier tillering onset in the former. Tillering in grasses is known to depend on temperature and light environment, ... -
Temperature impact on the forage quality of two wheat cultivars with contrasting capacity to accumulate sugars
Lorenzo, Maximo; Assuero, Silvia Graciela; Tognetti, Jorge Alberto (2015-08-17)Wheat is increasingly used as a dual-purpose crop (for forage and grain production) worldwide. Plants encounter low temperatures in winter, which commonly results in sugar accumulation. High sugar levels might have a ... -
Timing of nitrogen fertilization influences color and anthocyanin content of apple (Malus domestica Borkh. cv ‘Royal Gala’) fruits
De Angelis, Veronica; Sanchez, Enrique Eduardo; Tognetti, Jorge Alberto (Taylor and Francis, 2011)Different timings and methods of N application modify N dynamics in the plant and could have differential effects on fruit color. To evaluate this possibility, an experiment was conducted during three seasons in a ‘Royal ... -
Winter injury to grapevine secondary phloem and cambium impairs budbreak, cambium activity, and yield formation
Gonzalez Antivilo, Francisco Alberto; Paz, Rosalía Cristina; Tognetti, Jorge Alberto; Keller, Markus; Cavagnaro, Martín; Barrio, Eduardo Enrique; Roig Juñent, Fidel Alejandro (Springer, 2019-11-11)Vitis vinifera is a species of temperate origin that reactivates the dormant secondary phloem from the previous year at the resumption of growth in spring. Following harsh winters, grapevines may display a set of symptoms ...
