Question:
What is the effect of sunlight on the rate of germination in Taraxacum? Background: Germination is the process in which plants develop from seeds and begin to grow. The first process of germination is the uptake in water. Water is a key factor of rehydrating the Taraxacum through the process of germination. The next step, gibberellin is formed in the cotyledon. Then, maltose is transported to the embryo root from the food storage. Two important factors of seed germination in the Taraxacum are sunlight and temperature. Temperature is the first key factor, if the temperature is too high and the plant isn’t in the right conditions; for example in the shade or not properly watered, this could cause an altered rate in the germination process. On the other hand if the plant is in the cold it should be covered up or exposed to sunlight to help it gain nutrients from the sun, and undergo the process of photosynthesis, which could also affect the rate of germination.
Hypothesis:
I think that a seed that is kept under the same conditions, one at a higher temperature and one at a lower temperature, the seed that is surrounded by the higher temperature are going to grow faster due to the rays and nutrients from the sun allowing the seed to germinate.
Variables:
Manipulated Variables: Independent VariableAmount of Sunlight | Placing the planted seed in the shade or the sun. | Dependent VariableRate of Germination | The amount of sunlight will determine the rate of germination. |

Controlled Variables Taraxacum | I’m using two dandelion seeds, one in the shade, while the other is in the sun. | Temperature | When I place the planted seed in the sun the temperature will be hotter, as opposed to when I place the planted seed in the shade where it will be colder. | | | Water | Both plants will be watered twice a day until the process of germination begins. | Sunlight | One plant will have daily sun exposure, while the other plant will have little sun exposure. |

Materials: 2 Taraxacum seeds, black marker, 2 pots, water

Biology November 30, 2011 Arabidopsis: What Turns Seeds On An Interaction between At5Ptase1 and ABA Abstract An experiment was conducted to see how At5Ptase1 and ABA interacted. The At5Ptase1 gene has the ability to alter signal transduction. Abscisic acid (or ABA) is a principal drought-sensing hormone in plants. Compared to wild-type plants, some mutants showed delayed germination with the application of ABA (Burnette). The experiment was performed to see if Burnette had a point, and…

Phytochromes Cause Differences In Lettuce Seed Germination

Phytochromes cause differences in lettuce seed germination Abstract Plants use photoreceptors called phytochromes to discern what wavelength of light is being absorbed and respond accordingly. This experiment tests what happens when three different types of lettuce seeds are exposed to white light, red light, far-red light, and darkness. Lettuce seeds were placed in petri dishes and exposed to different wavelengths of light. The number or germinated seeds was recorded after 48 hours. The…

Allelopathy in a nut shell is chemical warfare between plants. Plants do this by creating chemicals that inhibit the germination and growth of neighboring plants. In a discussion with my Professor before the lab he talked about how we can notice and spot when a plants is allelopathic. In last week’s lab all the groups exposed seeds to two different types of…

production of a sterile triploid variety would be highly desirable for South African commercial forestry. Previous research on crosses between diploid and tetraploid parent plants to produce triploid progeny has resulted in poor seed set. One possible barrier preventing seed set could be the effect of temperature and relative humidity, within the isolation bags used during cross-pollination operations. For this reason in 2011 diploid polyads were subjected to various temperature and relative humidity…

Amanda Unger 230113075 Title: The rate of oxygen consumption by germinating peas at varying times during the germination process. Objective: The objective of this lab was to observe the rate of oxygen consumption of germinating peas at four times in the germinating process, 0 hours, 18 hours, 46 hours and 65 hours, and how the varying times of germination would affect the peas’ oxygen consumption during respiration. Null Hypothesis: The length at which the peas were left to germinate will not affect…
