    • 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 ...

    • 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. ...

    • 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 ...

    • Nucleolar activity in Triticum x Thinopyrum hybrids with different ploidy level 

      Fradkin, Maia; Greizerstein, Eduardo; Ferrari, Maria; Poggio, Lidia (Societa Botanica Italiana, 2016)
      The activity of nucleolar organizer regions (NORs) and the presence of ribosomal DNA (rDNA) zones were studied in two Triticum x Thinopyrum hybrids: a hexaploid hybrid with 2n = 42 chromosomes, named trigopiro SH16 INTA, ...

    • Cytogenetic studies in three diploid species of Andropogon (Andropogoneae), section Leptopogon 

      Hidalgo, María Irma de las Mercedes; Greizerstein, Eduardo; Norrmann, Guillermo (http://rodriguesia.jbrj.gov.br/, 2019)
      Karyotypes can provide a relevant information about relationships and evolutionary origin among species of the Andropogon genus. This paper presents the karyotype, C+ and DAPI/CMA3 banding and DNA content of three diploid ...

    • Amaranthus caudatus subsp. mantegazzianus: A new host of ‘Candidatus Phytoplasma hispanicum’ (subgroup 16Sr XIII‐A) 

      Noelting, Maria Cristina; Ferreira, Jacson; Rodrigues Galvão, Sarah; Greizerstein, Eduardo; Molina, Maria del Cármen; López, César Gabriel (wileyonlinelibrary.com, 2019-08-16)
      In Argentina, amaranth is a promising crop due to high nutritional quality and ability to grow in a diversity of environments. In areas cultivated with amaranth, were observed plants exhibiting slow growth, deformed ...

    • 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 ...

    • Rastrojo de maíz: producción teórica de etanol lignocelulósico en relación a la fecha de siembra 

      García Stepien, Ezequiel; Borlandelli, María Silvina; Roldán, D. O.; Ibáñez, Yanina (2017-09-01)
      El efecto de la fecha de siembra sobre el rendimiento y la calidad bioenergética del rastrojo de maíz (Zea mays L.) es poco conocido. Este recurso está siendo reconsiderado debido a que no compite con los alimentos y tiene ...

    • Caracterización genética de cuatro poblaciones de ovinos criollos de Argentina 

      Peña, Sabrina; Martínez, A.; Villegas Castagnasso, Egle; Aulicino, Mónica Beatriz; Género, Enrique; Giovambattista, Guillermo; Martínez, Rubén Darío (2017-12)
      Los ovinos criollos son los fundadores de la ganadería ovina en la Argentina y han contribuido de manera sostenida al desarrollo económico, social y cultural de algunas regiones del país. A pesar de ello, es un recurso ...

    • 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 ...
