【摘要】 [Objective]To study the effect of seawater stress on the germination of Celosia argentea seeds. [Method]Taking germination potential,germination rate,germination index,and vigor index as indicators,the germination performances of C. argentea seeds were measured at 5 concentrations of seawater stress to ascertain the salt tolerance. [Result]With the increasing seawater concentration,the germination rate,germination potential,germination index,and vigor index of C. argentea seeds showed a downward trend. When the seawater concentration reached 25%,the germination rate was still nearly 41%. When the seawater concentration was below 10%,the germination potential,germination index and vigor index of C. argentea seeds showed no significant differences. [Conclusion] C. argentea seeds could tolerate a certain degree of salinity stress when germinating.
