Question:
Will change in temperature affect the rate of seed germination in corn?
Introduction: When we look outside at our garden, we look at the beautiful and tasty vegetables that will soon make a great salad. Rows of string beans, radishes, tomatoes, and peas, are lavishly growing. As we wait patiently to harvest them, do we actually know the process in how they will begin to germinate? Germination essentially is when seeds will develop and grow to become new plants. In other words, germination occurs when a dry seed takes in water. As a result the embryo, which protects the seed, will begin to grow. Once germination is complete, visible structures such as the radicle surrounding the embryo will become apparent (Bewley and Black, 1994). When plants germinate there are several factors that may impact the process of germination. Those include temperature, light, pH level, and soil moisture (Shaban 2013). Without the right amount of each of these factors, it can either increase or decrease the rate of growth in germination.
For my research proposal, my independent variable will be temperature in corn seeds. Corn is easily bought in stores and the seeds are relatively cheap so that is one of the reasons why I want to use corn to test my hypothesis. According to …show more content…
They belong to a thermophilic species, meaning species who exist in warmer temperatures. When it comes to lower temperatures, it makes it difficult to strive for corn. If corn were to live in colder temperatures, a need for adaptation would occur. Corn would have to have a resistance to frost, chilling, soil fungi during germination, and able to germinate, grow maturely at low temperatures. (Brady, 1982) As a result when corn seeds start to germinate, cooler temperatures tend to slow down the process of germination. While warmer temperatures help the rate of germination in corn
