Aj. Devilliers et al., GERMINATION OF 3 NAMAQUALAND PIONEER SPECIES, AS INFLUENCED BY SALINITY, TEMPERATURE AND LIGHT, Seed science and technology, 22(3), 1994, pp. 427-433
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.
