Effects of salinity and temperature on germination of Kalidiopsis wagenitzii aellen (CHenopodiaceae)

In this study, effects of salinity and temperature on germination of Kalidiopsis wagenitzii Aellen seeds grown as an endemic in Salt Lake, Turkey were investigated. Seeds were germinated for seven days at the different NaCl concentrations (control, 50, 100, 200, 400 and 600 mM) and temperatures (5, 10, 15, 20, 25 and 30 °C) in the growth cabinets. The optimum germination temperature was found 25 °C and the percentage germination was 60%, 59% and 53% in control, 50 and 100 mM NaCl respectively. The present study showed that if the seed is protected from salinity and temperature stress, Kalidiopsis wagenitzii could germinate during early spring.
