Abstrakt: Seed germination in annual halophytes usually occurs when soil salinity levels are low and soil moisture is relatively high [1]. Optimum germination of halophyte seeds is often obtained under freshwater and inhibited by increasing salinity concentrations [2-4], but the ability to germinate at higher salinities is varied with species, for example Salicornia herbacea germinated at 1,700 mM NaCl [5], Arthrocnemum macrostachyum can germinate at 1,000 mM NaCl solution with 10% germination percentage [6]. Some secreting halophytes could also germinate above seawater salinity [7-11]. Most secreting halophytes show germination at NaCl concentrations ranging from 0.34-0.52 M NaCl. Few of them have low salt tolerance during germination [12-14]. [ABSTRACT FROM AUTHOR]
