Résumé : The dependence of seed storage life (longevity) on temperature and moisture content can be quantified and predicted using the seed viability equation. Survival data during storage of seeds of two varieties each of delphinium (Delphinium elatum L.) and salvia (Salvia splendens F.) at two temperatures (20 and 30 °C) and five relative humidities (33, 43, 53, 62, and 75%) were used to determine the constants of the seed viability equation. Normal seedling or radicle emergence scoring criteria for germination tests to assess seed viability were also compared. For salvia seeds, both criteria gave closely correlated results, while normal seedling counts were more reliable for delphinium seeds. Our results confirm the applicability of the seed viability equation for quantifying seed storage behavior, and provide values for the constants of the seed viability equation for two ornamental flower species.
