The Effects of Oiled Wisconsin Fast Plants Seeds on the Rate of Germination In this lab report, I will discuss the relationship between oil and the rate of germination of seeds. My Null hypothesis states that oil will not effect the rate of germination of Wisconsin Fast Plant seeds. The purpose of this experiment is to test the Null hypothesis. The symptoms caused by the contamination with oil are countless and generally not specific. The same substance can induce different effects in different species, and conversely, the same symptoms can arise from exposure to different substances (Baker, 1970). After an oil spill, an increase in the production of biomass and in the rate of germination of seeds can be observed. In this experiment,

We used paper towels in order to capture excess oil and water from the seeds. Next, we separated the Wisconsin Fast Plant seeds into six groups of ten. We then labeled each dish by trial and whether it is with or without oil: T1-W, T1-W/O, T2-W, T2-W/O, T3-W, T3-W/O. Following labeling, we placed one paper towel into each of the six three and a half inch plastic petri dishes. Next, we watered each petri dish with two to three milliliters of water. Then, we placed one of the six groups of seeds into each petri dish, on top of the paper towel. All seeds in each petri dish labeled ‘With’ will be sprayed with cooking oil one time. We used Pam cooking oil in our experiment. We sprayed three squirts of the oil onto each group of seeds, or until they were entirely coated in oil. Succeeding that, we put the lids of the petri dishes back on and cut around six inches of parafilm around all six of the petri dishes. We used parafilm in order to retain the water. Lastly, we placed all three of the trials under a florescent light until further data is collected. The seeds were under the light for a total of thirty-one hours. We collected data at the start of the trials, after seven to eight hours, after twenty-four hours, after twenty-seven hours, and finally, after thirty-one …show more content…
My results were random, meaning there was no set pattern of the ‘With’ groups germinating to a further extent compared to the ‘Without’ groups. Conversely, the ‘Without’ groups didn’t germinate more than the ‘With’ groups in every trial either. The rate at which my data supported my Null hypothesis is strong. This means that due to the nonspecific pattern of germination in the seeds, my collected results supported exactly what my Null hypothesis set out to test. I have concluded that oil has no effect on the rate of germination of
