Characterization of junglerice: growth habit and morphological plasticity determined by population density
Picapietra, Gabriel; Acciaresi, Horacio Abel (Brazilian Weed Science Society, 2024-02)Fondo: Numerosos estudios han descrito la competitividad del arroz selvático ( Echinochloa colona ) frente a cultivos, pero su comportamiento en cuanto a la densidad de plantas como resultado de la competencia intraespecífica ... -
Glyphosate resistance in perennial ryegrass (Lolium perenne L.) is associated with a fitness penalty
Yanniccari, Marcos Ezequiel; Vila-Aiub, Martín Miguel; Istilart, Carolina Maria; Acciaresi, Horacio Abel; Castro, Ana Maria (2016)The net selection effect of herbicides on herbicide-resistance traits in weeds is conditioned by the fitness benefits and costs associated with resistance alleles. Fitness costs play an important evolutionary role preventing ... -
Junglerice (Echinochloa colonaL.) seedling emergence model as a tool to optimize pre-emergent herbicide application
Picapietra, Gabriel; Acciaresi, Horacio Abel (Italian Society for Agronomy, 2021-07)Junglerice (Echinochloa colona), one of the worst and most problematic weeds globally, causes significant economic losses due to yield loss and control cost increase. Taking into account that this weed emerges in approximately ... -
Overcoming seed dormancy of junglerice (Echinochloa colona)
Picapietra, Gabriel; Acciaresi, Horacio Abel (Universidad de Concepción (Chile), 2022-08)Junglerice (Echinochloa colona L. Link) seed dormancy can persist 8 months after harvest and, once overcome, seeds can germinate over a long period of time. Light or high temperatures could overcome seed dormancy, while ... -
Predicting junglerice (Echinochloa colona L.) emergence as a function of thermal time in the humid pampas of Argentina
Picapietra, Gabriel; González-Andújar, José L.; Acciaresi, Horacio Abel (Taylor & Francis, 2020-06)Junglerice (Echinochloa colona) is one of the most important annual weeds affecting crops in Argentina. A predictive seedling emergence model based on thermal time was developed and validated. Monitoring of seedling emergence ... -
Responses to N Deficiency in Stay Green and Non-Stay Green Argentinean Hybrids of Maize
Antonietta, Mariana; Acciaresi, Horacio Abel; Guiamet, Juan José (2016-06)Breeding has developed better yielding maize hybrids for low N environments, which also have delayed leaf senescence (‘stay green’ trait, SG). Here, we studied whether the SG trait can further improve yield of modern hybrids ... -
Yield determinants, root distribution and soil water uptake in maize (Zea mays) hybrids differing in canopy senescence under post-silking drought
Antonietta, Mariana; Maydup, María Luján; Cano, María Gabriela; Fanello, Diego Darío; Acciaresi, Horacio Abel; Guiamet, Juan José (CSIRO Publishing, 2021-05)Delayed canopy senescence or ‘stay-green’ (SG) trait in maize (Zea mays L.) could improve drought tolerance. Two field trials comparing four to six maize hybrids with different senescence rate were carried out at Buenos ...
