Rate Of Germination Lab
In this lab the rate of germination in relation to temperature was observed testing the hypothesis, if the seeds are exposed to cold temperatures then they will not germinate. In the standard germination test a total of one hundred corn seeds were divided into four groups of twenty-five and each group was used to make a ragdoll. The rag dolls were germinated in room temperature. In the cold test one hundred corn seeds were placed on four layers of moist paper towels in the bottom of a metal tray, covered in moist soil and then were placed outside for eight days. After eight days they were allowed to germinate at room temperature for six days. The independent variable being tested is the temperature while the dependent variable is the germination rate. The standard germination test …show more content…
These characteristics allowed the seeds to be activated and it led to the seeds having a high germination rate. The cold germination test resulted in germination rates of 31%, 50%, 41%, and 53%, leading to an average of 43.75% germination. This low germination most likely occurred because of the low temperatures endured outside. The temperatures averaged about 45.7°F over the period of eight days. Corn grows best in temperatures eighty-five to ninety degrees fahrenheit. The temperatures the corn seeds were exposed to were not its optimum temperatures which led to the seeds not sprouting while outside. The corn seeds only sprouted when they were exposed to room temperature. The results gathered from these experiments proves the hypothesis, if the seeds are exposed to cold temperatures then they will not germinate. The results also show that the seeds need water and warm temperatures to germinate. These results could have been skewed by the varying temperatures the seeds were exposed to outside and inside the classroom. The temperatures in both locations did not remain

    We experienced a number of errors in our experiment. Sources of error were human interaction, inaccurate measurements, and incorrectly handling the seeds and materials. In the future, these problems can be avoided by interfering with the plastic bags that contained the seeds, adding the most accurate amount of solute as possible, or making sure that we don’t crush the seeds or the towel that was inserted in the bag. Ideas for future experimentation would be to plant the seeds outside so that the sun would be used as the…

    Abstract: This report examines Cellular Respiration and its functions as well as its function in germinating and non-germination peas. Cellular Respiration can best be described as a complicated string of chemical reactions. The complete Cellular respiration process begins with Glucose being oxidized, and the potential energy is transferred to the ATP molecule. The ATP molecule is now free to supply energy to the various processes within the cell. Water and Carbon dioxide are released during the process. This experiment aimed to conclude whether or not non-germinating peas are undergoing Cellular Respiration before they begin germination. This particular experiment required the following equipment: A thermometer, an Oxygen gas sensor, and a Carbon dioxide gas sensor. Temperature was also a factor in this experiment, as the effects of temperature on the rate of Cellular Respiration was also under study. The conclusion(s) of the study was/were as follows: Germinating peas experience Cellular respiration at a much faster rate than non-germination peas (however, non-germinating peas do undergo cellular respiration, but a much slower rate); it was also found that cooler temperatures affect the rate of respiration by slowing the process down.…

    The experiment was designed to test the hypothesis by planting an increasing number of genus Helianthus (sunflower) seeds in pots to see how they respond to increased density in limited space. Two replicates each of 2, 4, 8, 16, 32, 64, and 128 seeds were planted in similar size pots containing an equal mix of potting soil and perlite. All plants were kept in greenhouse conditions exposed to similar light and temperatures settings and were watered at equivalent intervals. At the end of the time period each pot was evaluated for number of seeds that had germinated as well as number of stems with blooms. Stems and blooms were cut and weighed.…

    A total of four petri dishes were removed in the dark, using only a green safelight. They were then labeled with the variety of seed, group name or initials, the date, and the light treatment. Filter paper was added to each pert dish and then 2-3 dropperfuls of water were added to each plate so that the filter paper was very moist for germination. Then 25 lettuce seeds were placed into each dish. The light regimens were White, Red, Far-Red, and Darkness. Each dish was exposed to their labeled light regimen for 10 minutes. They were kept level and wrapped in foil immediately after exposure. After 48 hours, the seeds were revisited and the total number of seeds germinated in each dish was determined, then figured into a percentage. All the information was gathered together and put into…

    This experiment had the purpose of testing temperature for bean and pea seed germination. 100 beans were taken and split into four groups of 25. Each Group of 25 beans was folded inside a damp paper towel. Two of the damp paper towels, with the beans inside, were put in a plastic bag and then moved to a warm place and the other two paper towels were put in a plastic bag and then moved to a cold room. The same process was repeated for the peas. It was hypothesized that the beans and peas that were put in the warm room would germinate fastest. When the seeds were taken out of the rooms for examination one week later all 25 of the beans that were in the warm room, in both rep one and rep two had germinated. As for the peas in the warm room, 15 of the 25 peas had germinated in rep one and in rep two 8 of the 25 peas had germinated. None of the beans and peas in the cold room had germinated at all in the first week. The second week the remaining 7 peas for rep one in the warm room had germinated and the remaining 10 peas from rep two in the warm room had germinated. In the cold room for the second week none of the beans had germinated. All 25 of the peas in the cold room, in reps one and two finally germinated in week two. The data shows that beans germinate in a warm room and peas tolerate warm temperatures, but germinate best in colder temperatures. Beans have a greater success rate of germinating in a warm environment then peas do, but peas have a greater success rate of germinating in a cold room.…

    Seed germination and growth are influenced by many factors. Some of these are the environment, light quality and moisture availability. Other factors which may influence seed germination are a result of the environment surrounding the seed, like alleleopathy. In this experiment we are going to study the alleleopathy of garlic. Using the scientific method of inquiry, my group and I are experimenting if the volatility of the crushed garlic will affect germination and growth of the radish seeds.…

    This supported the null hypothesis that states presoaking seeds will have no effect on germination. However , the experiment gave no data on how moisture will affect germination. It also didnt give any definative answer as to if presoaking helps germination in any way. Errors in the way the experiment was designed may explain why the lab bared no results. All of the seeds were placed in inconsistent amount of light, which means that was another variable in the lab.…

    An abstract in the Canadian Journal of Botany found at www.nrcresearchpress.com/doi/abs/10.1139/672-308 states, "The changes in total lipid, fatty acid, and lipid phosphorus contents were followed during germination and early growth of Rideau wheat seedlings at 24 degrees C for 72 h and 2 degrees C for 5 weeks. At both temperatures the changes in total lipids and total fatty acids were similar for seedlings at comparable stages of morphological development. In contrast, the phospholipid content of seedlings grown at 2 degrees C was considerably higher than that of seedlings grown at 24 degrees C. A marked increase in linolenic acid was also observed during growth at 2 degrees C, and this change occurred entirely in the embryo. The results indicate an increased synthesis and unsaturation of membranes in seedlings grown at 2 degrees C. The changes may contribute to the increased resistance to freezing temperatures exhibited by seedlings grown at 2 degrees C."…
