Summary Salinity is one of the greatest challenges of successful agricultural production worldwide. However, seed priming might be efficient practice for enhancing seed germination and initial plant growth and development. This experiment was undertaken with the aim of assessing the impact of different priming methods on seed quality parameters and early growth of garden pea (Pisum sativum L.) cultivars under salinity stress. Pea seeds of three different cultivars were primed with water (hydropriming), KNO3 solution (0.5%), and PEG 6000 solution (-0.5 MPa) for 24h in the dark. Unprimed and primed seeds were germinated between filter papers saturated with 120 mM NaCl using the germination test. The results clearly showed that the examined parameters of primed pea seeds were substantially greater than the parameters of unprimed seeds under saline stress. Moreover, seed priming with KNO3 and PEG solutions were more effective in improving seed quality and initial growth in garden peas than hydropriming.
