Abstract：Using the Limonium sinense seeds from Dongying and Binzhou of Shandong Province as materials,the effects of seawater stress on its seed germination and seedling growth were reserched by using the germination potential,germination percentage,germination index and vigor index of seeds and the height and root length of seedlings.The results showed that the germination potential,germination percentage,germination index and vigor index of seeds from the two regions were all inhibited under seawater stress at the concentrations of 3％,25％,50％ and 67％ (volume fraction),so were the seedling height and root length.But under the stress of 6％ seawater,the seed vigor index increased,and the seedling growth was promoted.The root length was slightly inhibited under the stress of 12％ seawater.Almost all the seed germination of Limonium sinense from two regions was inhibited under the stress of 67％ seawater.Through comparison,the Limonium sinense from Binzhou was less influenced by seawater stress,and showed stronger salt resistant ability.
