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 ...

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 ...

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 ...

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 ...

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 ...

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. ...

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 ...

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 ...

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, ...
