Eco-physiology of maize crops under combined stresses
(Wiley, 2023-12)The yield of maize (Zea mays L.) crops depends on their ability to intercept sunlight throughout the growing cycle, transform this energy into biomass and allocate it to the kernels. Abiotic stresses affect these ... -
Efecto del estrés por altas temperaturas y fertilización nitrogenada en el rendimiento en el algodón
(Asociación para la Promoción de la Producción Algodonera, Argentina, 2018)En un contexto de cambio climático a escala mundial, es probable que la futura producción de algodón ocurra bajo una mayor prevalencia de múltiple estreses abióticos, incluyendo temperaturas extremas y prolongadas. Si bien ... -
Effect of cold stress at cellular and foliar level and regrowth capacity of three Cenchrus ciliaris L. cultivars: Americana, Biloela and Texas 4464
(Universidad Nacional de Cuyo, 2019)Buffelgrass (Cenchrus ciliaris L.) a native pasture species of Africa is widely used in arid regions because of its forage productivity and quality. It could become serious invasive species, not only for crops but also in ... -
Effect of combined stress (salinity + hypoxia) and auxin rooting hormone addition on morphology and growth traits in six Salix spp. Clones
(Springer Nature, 2019-04-15)Willows plantations development could be an alternative for hydro-halomorphic soils but it is limited by combined stress salinity + hypoxia (main stressor under waterlogging conditions). We studied the effects of saline ... -
