Abstract
The effects of salinity (simulated sea-water), temperature and light o n seed germination of three Namaqualand pioneer species, were investig ated. Increased salinity caused a significant decrease in germination percentages and delayed mean germination time. The highest germination percentages occurred at temperatures of 15 degrees C for Senecio eleg ans, 20 degrees C for Dimorphotheca sinuata, and 25 degrees C for Atri plex semibaccata. The effect of light differed depending on species, t emperature and salinity.
