Senecio coincyi (Asteraceae) is a threatened endemic plant of central and north western Spain with a very narrow occurrence. In this study, germination tests under controlled conditions of light and temperature were carried out to evaluate interpopulation variation in the germination patterns of S. coincyi cypselas from 12 populations. The effects of nitrate (1, 5, 10, 25 and 50 mM KNO3) on percentage and rate of germination were also determined. Untreated cypselas of S. coincyi reached very high germination percentages (83-94%, depending on population), and there was no significant differences depending on population. In contrast, there were significant differences among populations in germination velocity, both for untreated and treated seeds. For all studied populations, KNO3 concentrations from 1 to 50 mM did not significantly affect germination percentage. Similarly, there was not a significant effect of KNO3 at concentrations in the range of 1 to 25 mM on germination speed. Only the highest KNO3 concentration (50 mM) significantly decreased the germination speed of the cypselas from most of the populations.
