Dynamics of Dry-Down in Seed, Head and Stalk from Sunflower Genotypes Sprayed with Chemical Desiccants After Physiological Maturity
Szemruch, Cyntia; García, Federico; Zuil, Sebastián; Teysseire, Christian; Renzi, Juan P.; Cantamutto, Miguel A.; Renteria, Santiago; Rondanini, Deborah (Turkish Journal of Agriculture - Food Science and Technology, 2019-01-10)Chemical desiccation can advance the sunflower harvest time. Paraquat has been extensively used, but other less risky chemicals, as Carfentrazone and Saflufenacil, can rise as an alternative. Moisture levels of seed, head ... -
EFECTO DE LA TECNOLOGÍA DE INCRUSTADO SOBRE LA CALIDAD FISIOLÓGICA DE SEMILLAS DE GIRASOL (Helianthus annuus L.)
Szemruch, Cyntia (Universidad Nacional de Córdoda, 2011)La siembra de precisión de las semillas de menor calibre de girasol (Helianthus annuus. L) se ve dificultada por la gran variabilidad en su tamaño y forma. El incrustado podría resolver este problema a través de la ... -
Electrical conductivity test for predict sunflower seeds vigor
Szemruch, Cyntia; Gallo, Carina; Murcia, Mónica; Esquivel, Maximiliano; García, Federico; Medina, Juan; Magnano, Luciana (SSRG International Journal of Agriculture & Environmental Science (SSRG-IJAES), 2019-07)There is no standardised test for predicting sunflower seed vigor. The electrical conductivity test (EC) produces faster results. Before a test is standardised requires a validation process to ensure reliable and reproducible ... -
Encrusting offers protection against phytotoxic chemicals and maintains the physiological quality of sunflower (Helianthus annuus) seeds
Szemruch, Cyntia; Ferrari, Liliana (Seed Science Technolgy, 2013-01)Precision planting of sunfl ower seeds is hampered by the large variability in size and shape. Seed encrusting, the application of layers of adhesive and inert material, has the potential to solve this problem. However, ... -
Estandarización nacional del método de conductividad eléctrica para analizar el vigor de semillas en girasol
López, César Gabriel; Szemruch, Cyntia; Gallo, Carina; Murcia, Mónica; Esquivel, Maximiliano; Aranguren, María Belén; García, Federico; Medina, Juan; Rondanini, Deborah (2018-06)Objetivos del IIPAAS: Objetivo general: Validar a nivel nacional el test de conductividad eléctrica para medir el vigor en semillas de girasol. Objetivos específicos: 1. Confirmar la clasificación del vigor en base al test ... -
Field vigor of sunflower seeds after chemical treatment
Szemruch, Cyntia; García, Federico; Aranguren, María Belén (Advances in Agricultural Science, 2019-01)Sunflower is a globally important oilseed, food and ornamental crop. To prevent the attack of insects and diseases during field emergence, sunflower seeds are usually treated with insecticides and fungicides, respectively. ... -
Germination, vigour and dormancy of sunflower seeds following chemical desiccation of female plants
Szemruch, Cyntia; Renteria, Santiago; Moreira, Fabiana; Cantamutto, Miguel; Ferrari, Liliana; Rondanini, Deborah (Seed Science and Technology, 2014-11)The aim of this study was to analyse the impact of chemical desiccation on (i) the germination and vigour of seeds of contrasting sunflower genotypes, and (ii) the level of seed dormancy, with emphasis on the anatomical ... -
Hybrid sunflower seed yield, composition and deterioration after chemical desiccation
Szemruch, Cyntia; Cantamutto, Miguel; García, Federico; Aguirre, Matias; Renteria, Santiago; Rondanini, Deborah (International Journal of Plant Production, 2017-04)The impact of chemical desiccation on yield showed contrasting results depending on seed moisture content at the time of application. Its effects on seed deterioration are still unknown and could be modified by seed ... -
INFLUENCIA DEL DESECADO QUÍMICO DEL CULTIVO SOBRE EL RENDIMIENTO Y CALIDAD DE SEMILLAS HÍBRIDAS DE GIRASOL
Szemruch, Cyntia (Universidad Nacional de Sur, 2017)Argentina es un destacado productor de semillas híbridas de girasol. La desecación química se emplea para adelantar la cosecha y reducir la incidencia de adversidades bióticas y abióticas. En cultivos para semilla, se ... -
Ranges of Vigor Based on the Electrical Conductivity Test in Dehulled Sunflower Seeds
Szemruch, Cyntia; Del Longo, Olga; Ferrari, Liliana; Renteria, Santiago; Murcia, Mónica; Cantamutto, Miguel; Rondanini, Deborah (Research Journal of Seed Science, 2015)Electrical Conductivity (EC) is a promising vigor test since it produces fast laboratory results. In sunflower, the leakage of electrolytes from the pericarp may interfere with exudates from embryo tissues. The aims of ... -
