Abstract In this experiment normal soybeans, that can be purchased in any grocery or local seed shop, and genetically modified soybeans, which were ordered via the Carolina science company, were used to test the effects of temperature and UV light on soybean growth and germination rate. One half of the seeds were then placed in a small 26C incubator and allowed to grow for 8 days. The remaining half of the seeds were put in a tray out in room temperature (about 20C- 25C) for 8 days and allowed to grow. Measurements in cm were taken each day. The next trial a second variable was introduced and this was that the same number of seeds were exposed to UV light and then placed in a heat or control environment. Then the same amount of seeds were planted and were not given and exposure to UV light and planted in both the heat and control environments. These plants were then all allowed to grow for 8 days, and then the trial was repeated.

Need Genetically modified foods are virtually everywhere in today's markets, but it is unsure if they have any flaw (growing slower, more vulnerable to the elements etc.) Not much testing has been done on the growth and germination cycles of genetically modified foods UV light and temperature’s effects of soybeans have been tested but they have not yet been tested on genetically modified soybeans.

Methodology The Effects Of UV Light And Temperature On Genetically Modified Soybean And Normal Soybean Growth 6 (per trial) genetically modified soybeans were exposed to UV light and then placed in a 26C incubator. 6 (per trial) normal soybeans were exposed to UV light and then placed in a 26C incubator. 6 (per trial) normal soybeans were exposed to UV light and then placed at room temperature (25C). 6 (per trial) genetically modified soybeans were placed at room temperature (25C) 6 (per trial) normal soybeans were placed at room temperature 6 (per trial) normal soybeans were placed in an 26C incubator 6 (per trial) geneticall y modified soybeans were placed in a 26C incubator 6 (per trial) genetically modified soybeans were placed at room temperatu re Measurements in cm were taken everyday, each test lasted about a week and a half (8 days) Measurements of the height (in cm) of the plants stem and leaves were taken Quantitative data was taken as well as some qualitative data that was used (plant health) and these were to calculate the mean of these plants.

Purpose Many farmers search for better ways to grow their crops and researchers around the globe dedicate their lives to helping these farmers by means of their research. A great deal of research has been done to assist soybean farmers including the effects of temperature and also UV light on soybean growth and germination rate. Genetically modifying seeds and planting them is yet another way that scientists may help farmers. However there is almost no research done about the effects of these variables (temperature and UV light) on the effects of genetically modified soybean growth.

Lit Review S. K. TYAGI and R. P. TRIPATHI, Warmer temperatures increase soybean germination and also growth, colder temperatures discourage growth. Large amounts of soil moisture assist soybean growth but after 15% of the soil was moistened growth was discouraged. Eileen Feilmeier Wuebker, Russell E. Mullen, and Kenneth Koehler Warmer temperatures increase soybean growth and longer periods of flooding also tend to increase soybean growth, however after 2 or 3 days of flooding soybean germination percentages greatly decrease.

Null Hypothesis When seeds are not exposed to UV light and are placed in a control environment they will grow faster and healthier than the seeds which have been exposed to UV light and are placed in a heat environment.

Alternate Hypothesis When seeds are exposed to small amounts of UV light and are placed in a heat environment they will grow at the same rate as the seeds which have not been exposed to UV light and are placed in a control environment.
