Abstract Salinity causes imbalances in endogenous level of different dormancy regulating chemicals (DRCs) of seeds, resulting in germination inhibition and/or viability loss. Exogenous application of DRCs could therefore be an effective means to mitigate salinity effects on seed germination. In this study, we compared (1) salt tolerance and (2) variability and efficacy of various DRCs on seed germination of Great Basin halophytes under controlled laboratory conditions. Optimal seed germination of all test species was observed in distilled water and increases in salinity generally decreased seed germination. Exogenous application of all DRCs enhanced seed germination at all salinities, with more alleviations under high salinity. Ethephon, fusicoccin and kinetin treatments were generally most effective than others. While, Salicornia rubra and Sarcocornia utahensis responded to nearly all DRCs in comparison to other species. Our results thus indicate that effectiveness of DRC treatments could be salinity, species and chemical specific.
