Abstract
In order to study on the E.prostrata seeds' tolerance to soil salinity,effect of seawater of different concentrations on the germination of E.prostrata seeds were studied.The results showed that E.prostrata seeds need light to germinate;seawater of lower than 1% concentration had a positive effect on eclipta prostrata seed germination,whereas seawater of lower than 10% concentration has no significant effect on the seed germination rate.Based on the two indicators of the germination vigor and germination index,it can be inferred that E.prostrata seeds could tolerate seawater of lower than 3% concentration.
