Effects of salinity on seed germination, seedling growth and survival of Spartina ciliata Brong

摘要: The effects of different salinities on the germination Spartina ciliata seeds were tested during 40 days in laboratory, using six concentrations NaCl (0,45, 80, 130, 170 and 215 mM) besides three seawater (25,30 35‰). In addition, survival growth seedlings five constant salinity regimes 80 mM NaCl) as well simulating overwash. results showed that possed a high capacity over wide range (0 to NaCl). Although close full-strength completely inhibited seed germination, transfer ungerminated freshwater immediately stimulated this. seedling shoot height root length variables most sensitive salt stress. Frequent overwash with significantly reduced seedlings. success survival, above those normally found natural environment could explain species being distributed throughout salt-stressed foredune habitats southern Brazil.
