Abstract Effect of different chemicals: kinetin (0.05 mM), ethephon (5 muM), GA(3) (0.3 mM), proline (0.1 mM), betaine (0.1 mM), nitrate (10 mM) and thiourea (5 mM) was investigated in alleviating salinity enforced seed dormancy from Limonium stocksii. Six salinity regimes (0-500 mM NaCl) were used in 12 h photoperiod and in complete darkness to study the effect of different germination regulating chemicals in inducing germination under saline condition. Only kinetin and ethephon successfully alleviated salinity enforced seed dormancy of L. stocksii. Kinetin was more Successful than ethephon. Seed germination was substantially inhibited by salinity when germinated under complete darkness. Kinetin and ethephon appeared to be the only chemicals which improved seed gemination in complete darkness. All other germination regulating chemicals had no effect at low salinity but inhibited germination at high salinity in both light and dark.
