| Abstract | Seeds with high germination percentage and low mean germination time are generally good for seedling establishment resulted in good subsequent growth. This experiment aimed to study the effects of different seed soaking times in various concentrations of different solutions. The experiment was conducted using a split-plot design in a Completely Randomized Design (CRD). The main plot was 4 soaking times: 6, 12, 18, and 24 hours. The sub plot was different solutions at various 7 concentrations: chitosan, 20, 40, 80 ppm, ascorbic acid, 20, 40, 80 ppm and water. The sunflower seeds were soaked in the various solutions (sub plot) as designated times (main plot), then air-dried for 1 hour before sowing to test germination percentage and seedling vigor. The results showed statistically significant differences among soaking times, soaking the seeds for 18 hours resulted in higher germination percentage, longer seedling shoot and root length, as well as higher fresh weights of both shoot and root compared to those of the other soaking times. However, soaking the seeds in various solutions with different concentrations did not show statistically significant differences. However, there was a trend indicating that germination percentage and seedling growth were higher when the seeds were soaked in ascorbic acid solution at the concentration of 40 ppm. In conclusion, soaking the seeds in ascorbic acid solution at a concentration of 40 ppm for 18 hours had a positive effect on the germination percentage and subsequent growth of sunflower seedlings. |
