dc.description.abstractStudies were conducted from 2007 to 2008 to determine the effect of temperature, salt stress and plant depth on germination of the aerial and subterranean seed of Benghal dayflower. The seed was harvested from mature pods of the plant, cleaned and allowed to dry for two days before the experiments began. Tests were conducted in the greenhouse and growth chamber. Data indicated that the aerial seed had a higher germination percent for the temperature treatment. The highest germination percent was 90% at 30°C. The 20°C treatment had a cumulative germination of only 30% indicating that emergence could still be sustained even at these low temperatures. Germination was 45 and 15 % for the 10 and 20 mM concentration, respectively. No germination occurred with the 40 mM salt concentration. The highest germination was at 0 and 1 cm plant depth. No germination occurred in the 12 cm plant depth.
