We wanted to figure out how important the seed coat is to the germination of a seed. For our experiment we focused on six types of seeds, ranging from green peas to chickpeas. We soaked 30 seeds of each type then removed the seed coat of 10 seeds, nicked another set of 10 seeds, and left the remaining 10 seeds alone. The seeds were then placed in petri dishes with a moist paper towel, all conditions being held constant. Over the course of four days we checked on the seeds every twelve hours. We noted the number of seeds that germinated and any other traits that stood out to us. Every type was photographed as well and uploaded into a shared folder. I was actually surprised about our results. I believed that seeds with a tampered seed coat would not germinate as well as a normal seed. However, the graphs reveal that for most types, seeds with a nicked coat germinated sooner and in greater numbers. From handling the seeds, I also believed that seeds with a thicker coat may actually germinate faster if they are nicked. Again, there was no distinct difference found between seeds of thick or thin coats. If we had more time to run this experiment again I would have liked to use seeds of varying coat thickness. From our results, I feel that I cannot confidently concluded anything significant from our data since it was such a small data set. We found some results that would suggest nicking the seed coat would allow for the seed to germinate more efficiently, but more evidence is required to make that statement statistically significant.
