dc.description.abstract
Electrical Conductivity (EC) is a promising vigor testsince it produces fast laboratory results. In sunflower, the leakage of electrolytes from the pericarp may interfere with exudates from embryo tissues.The aims of this work were (1) To determine the utility of the EC test using dehulled (without pericap) sunflower seeds to evaluate the vigor in different genotypes, exposed to contrasting seed filling period and storage conditions,(2) To explore the relationship between EC and germination values near postharvest and across storage period and (3) To propose ranges of vigor throughEC, so as to categorize sunflower seeds lots. Seeds of commercial hybrids differentiated by acid composition (high and standard oleic acid), exploring contrasting seed filling period and storage conditions, were evaluated by EC,Tetrazolium (TZ-V) and Germination (G), near post harvest time and duringstorage period (1, 5, 9, 13 and 19 months). An independent set of 18 genotypes,stored during 1-108 months, were also analyzed for EC and G. Electric conductivity in dehulled seeds was effective to identify vigor differences ofgenotypes in different seed filling period and storage conditions. A general relationship between the loss of germination and vigor was established for sunflower.The ranges of vigor based on EC proposed for sunflower seeds classification were <70 uS/cm/g for high, 70-110 for intermediate, and >110 uS/cm/g for low vigor levels. It is the first report based on EC ranges to categorize the seed vigor of sunflower seeds lots
