Over a one week period, the germination rate in a variety of seed species was tested between seeds with and without testa. Particular species of seeds provided evidence of fast germination while others did not. A t-test concludes that there is no significant difference between the germination rates of seeds with or without testa. The germination rate of seeds with testa is equal to the germination rate of seeds without a testa. Uncertainties in our experiment include meeting the optimal environment for each species of seed, as well as the uneven distribution of water to the seeds. Furthermore, a small sample size experiment increases the likelihood of falsely accepting the null hypothesis. Another question our experiment brings up is whether the difference in germination rate between seeds with and without testa is practically significant. Even if the mean germination rate is truly significantly different from seeds without testa, what would industries have to invest to make this happen, and if so, would it be worth it?
