Abstract:
      A study was carried out to determine the germination ability of seeds in three halophytes, which were treated with various concentrations of NaCl(neutral salt) and Na2CO3(basic salt). The result showed that seed germina-tion rate decreased as salinity increased and that negative correlation between the seeds germination percentage and salt concentration was marked. The related coefficient of Suaeda salsa, Suaeda glauca and Kalidium foliatum are 0.9206, 0.8989 and 0.8956 in neutral salt(NaCl), and 0.9148, 0.7193 and 0.6327 in basic salt(Na2CO3). The optimal ger-mination of the seeds of three halophytes was obtained in distilled water. The inhibitory effect of Na2CO3 on seed germina-tion was stronger than that of NaCl.
