Each group received 30 seeds of the same soybean species, totalling 6 species and 180 seeds total. One set of 10 seeds served as a control, 10 were nicked with a small needle, and 10 were manipulated so that the seed coat was completely removed.
We placed each set of seeds in a large petri dish with a wet paper towel. The dishes were labeled with the type of seed and the treatment that the set received.
The seeds were covered and left to sit for 3 ½ consecutive days, and we checked them for germination at 8 am and 7 pm every day. Each group member re-added water to a paper towel if it had dried out. We recorded the amount of seeds in each dish that had no change, began germination, were germinating, and have stopped germinating at every check-in time.
