The goal of our project was to observe the effects that manipulating the seed coat had on germination rates in soybean species. The seed coat is important for protecting the seed, but we were wondering if it is at all necessary for initial growth to occur. To test this, we had some serve as a control group, some where the coat was nicked with a needle, and some where the seed coat was completely removed. Over the course of 3.5 days, the seeds stayed in petri dishes with wet paper towels, and we periodically checked all the seeds and recorded how many of each treatment had germinated. Because another group completed this project with us, we focused mostly on how the control group's germination rates differed from that of the nicked group. Our results showed a trend in faster germination among the nicked seed coats, but after statistical analysis we cannot conclude that nicking of the seed coat leads to faster germination. We must say that the differences observed most likely occurred by chance.
