Priming is a technique which enhances seed quality and has a wide range, from increasing germination efficiency to increasing plant productivity. In this study, the effects of priming treatments on rapeseed seed longevity under different storage conditions were investigated. Seeds of 'Dk-xpower', 'Hayola50' and 'Traper' rapeseed cultivars were given hydropriming and osmopriming pre-treatments. Hydro- and osmoprimed seeds and non-primed (control) seeds with 6 and 9% MC were aged at 15, 25, 35 and 45┬░C and their viability was evaluated after different periods of time. The results indicated that there were significant differences between the cultivars in response to priming treatments and storage conditions. Priming treatments affected both Ki and σ, thus improving initial quality as well as seed lifespan. Hydropriming was more effective than osmopriming in improving longevity, although the response was not always consistent across storage conditions and cultivars.
