Germination Lab

In the dishes, I dropped the appropriate treatment into the center, where the marks were made. Next, I closed the petri dishes, taped them up, and let them sit at room temperature for a week. Then I opened them up to take two measurements. The first measurement was the number of seeds germinated. The second measurement was to measure the seedling lengths.

The experiment was begun by obtaining four 8 oz. Styrofoam cups and punching a hole through the bottom of them. This hole was for water entry or excess water drainage. Moistened soil was packed to the 1/2 full line in the cup along with 3 fertilizer pellets The cups were labeled the following: Rosette-H20, Rosette-GA, Wild-Type-H2O, and Wild-type- GA.(Handout 1) A small wooden applicator stick was obtained a moistened at the tip with water from the petri dish labeled ‘water.’ This was to be able to attract the seed to the applicator in order to place the seed from its original container into

The purpose of this experiment is to observe the effects of Sodium Chloride (NaCl) on the germination rate of Wisconsin Fast Plants.

The seeds soaked in the salt solution did not have any change in appearance while the seeds exposed to the vinegar solution generally appeared to become darker in color and shriveled. For the 10% fertilizer solution only one replication produced germination (6 out of the 10 seeds in the petri dish germinated). The seeds that did not germinate for the 10% fertilizer solution appeared darker in color. Seeds exposed to distilled water (control) had germination across every replication group and produced some fairly large sprouts. The 10% soap solution seeds also had germination in every replication group, but the size of the sprouts were not as large as the ones in the control group.

Something that can be concluded from this is that a major change in planting depth does affect seed growth. Another experiment that provided similar results was conducted by J. L. Beveridge and C. P. Wilsie. In the journal article “Influence of Depth of Planting, Seed Size, and Variety on Emergence and Seeding Vigor in Alfalfa”, the writers explain, “Emergence of seedlings of three varieties of alfalfa decreased as depth of seeding was increased.” (Beveridge and Wilsie).

Firstly, for the setup of the experiment, two styrofoam cups were filled with two inches worth of standard, fertilized garden soil, next four seeds from from the garden seed, and the bird seed were placed an inch deep in separate cups. The seeds were blindly labeled, with one being labeled group A and one being labeled group B. This was so as to efficiently conduct a double blind experiment. The seeds were watered with approximately a teaspoon of water per day, and kept in a sunny windowsill. They were left in the windowsill for two weeks, and watered daily.

The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.

This then not only prevents the germination of the seed; however, if the plant were to initially germinate, it would be unable to grow any further, as without enough water, photosynthesis, nutrient transfer, or transpiration would be unable to occur; therefore, the plant would be unable to sustain (Growing Anything,

Take the bowl of water and the paper towels. Submerge your hand in the water, then pat the paper towel with your hand, to dampen the towels before planting but not to the point where the towels are soaked. Do this for each group of seeds soaked in the solutions (5).

The second step of the experiment was to soak the seeds in water overnight. This action was made to prepare the seeds for germination and making them more softer and less rigid. The seeds were placed in a bowl and were covered by tin foil. It was set up on the refrigerator to minimize any outside interference that may come to it. After a full night of absorbing the water, the seeds were ready to start the next stage.

Title Which soda, either Coke, Sprite, or Mountain Dew, would reduce seed germination rate the greatest ? Purpose The purpose of the experiment was to see if soda, either Coke, Sprite, or Mountain Dew had an effect on a morning glory seed’s germination rate, and to see if the effect of Coke, Sprite, and Mountain Dew soda on seed germination is the same as the effect of the Coke, Sprite, and Mountain Dew on humans. Background Research: Seed germination is a process that is defined as a seed developing into a new plant.

Some factors that affect seed germination are temperature, light and moisture. Most seeds tend to germinate quicker with the presence of water. In my experiment, Pot B did not germinate at the same time as Pot A. This was most likely because Pot B was exposed to more sunlight causing the water to evaporate and leaving the seeds with little

Purpose: To see the effect of an acid introduced during seed germination, on the length of the plant roots. Also shows how salt can affect the seed germination. Acid can be introduced to seeds during germination if there is acid rain. Knowing the results of acid rain on seed germination will help us understand how to grow pants better, and how to have more successful germination. Salt can be introduced into a seed during germination because salt is put on roads and the salt builds up and can contaminate the soil. Knowing the effects of salt on seed germination will allow us to know for sure if the salt is affecting the plants growth or not.

Research of Photosynthesis By: Daniel Ortiz Biology 1 1st hour Jan Baptist van Helmont: Willow Tree experiment In “The Willow Tree experiment” Jan Baptist van Helmont said that; If you only water a willow tree, then it will grow like a regular tree. In the experiment he used just a regular willow tree and distilled/rainwater. He changed whether he used rainwater, or distilled water to water the tree. Though he kept the plant the same (Willow Tree.)

The purpose of the project was to determine whether Eucalyptus globulus had an effect on the germination of radish seeds. It was hypothesized that Eucalyptus globulus would have a negative effect on the germination of the seeds and their growth.
