Uso del Test de Conductividad Eléctrica para la estimación del vigor y la emergencia a campo de semillas de girasol.
(Revista Para Mejorar la Producción. INTA Oliveros, 2019-08-15)
El empleo de semillas de alta calidad mejora la probabilidad de obtener una emergencia rápida y uniforme
en los cultivos. Existen varios atributos incluidos en la calidad de semillas, entre ellos el vigor, que representa ...
Dynamics of Dry-Down in Seed, Head and Stalk from Sunflower Genotypes Sprayed with Chemical Desiccants After Physiological Maturity
(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 ...
Ranges of Vigor Based on the Electrical Conductivity Test in Dehulled Sunflower Seeds
(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 ...
Hybrid sunflower seed yield, composition and deterioration after chemical desiccation
(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 ...
Electrical conductivity test for predict sunflower seeds vigor
(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 ...
Field vigor of sunflower seeds after chemical treatment
(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. ...
Estandarización nacional del método de conductividad eléctrica para analizar el vigor de semillas en girasol
(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 ...
Germination, vigour and dormancy of sunflower seeds following chemical desiccation of female plants
(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
...
Encrusting offers protection against phytotoxic chemicals and maintains the physiological quality of sunflower (Helianthus annuus) seeds
(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, ...
