Germination and Beans
Notes about bean germination: * The time to germination will decrease if you soak the beans overnight * It may take 7-10 days for the beans to ‘sprout’ * Make sure the paper towels remain moist for the duration of your experiment | | | | | | | | | |
Procedure
1. Think of 10-20 variables that may affect seed germination, recording them in Table 3. 2. From your list of variables in Table 3, select three to test. Form a hypothesis for why each affects seed germination. 1. Cold Temperature 2. Water (presoaked) 3. Warm Temperature 3. To germinate the beans, place one folded paper towel, moistened but not soaking wet, into the 5 x 8in bag. Place 10 beans in a horizontal line on the paper towel (between the paper towel and bag). 4. Label each bag with the variable being tested.
Table 3: Variables that may influence seed germination Variable | Hypothesized Effect | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 5. Hang each bag vertically using masking tape in the environment you select. 6. Create a table for your data, including title, units, and any other useful information. 7. Select the appropriate type of graph, and report the data you collected. 8. Write a lab report for this experiment in the space provided.
Lab report
Of the seeds germinated only 20 actually emerged as of this report.
The results are located in the following tables and graphs.
This graph shows the results of 10 beans; contained in 3 separate bags. 1. Containing seeds dampened prior to placement in container wrapped in damp paper towels. 2. Containing seeds placed in damp paper towels in cooler temperature. 3. Containing seeds placed in damp paper towels in placed in farmer temperature.

This graph shows the results of 10 beans; contained in 3 separate bags. 4.

    An avocado seed is used in this experiment. For this type of seed to start the process of germination, the favorable climate is typically very warm. If someone was to plant an avocado seed and see the quickest results, they should place the seed in the sun. Along with waiting a few days between watering the seed, allowing the soil to dry out. For the seed to germinate properly, the bottom half of the seed will be emerged into water. Once the top of the seed becomes dry it will crack and the exterior brown skin will come…

    Miracle Gro Lab Report

    The purpose of this lab was to determine which concentration of Miracle Gro was ideal for the germination of seeds. I hypothesized that the 1.25% concentration of Miracle Gro would allow the plant to grow the fastest, unfortunately, my data does not support my hypothesis. According to the information we collected, the amount of concentration with the fastest speed and greatest height of growth was the 0% with plain tap water (control group). Two days after “planting,” my group measured the seed with the greatest rate of growth: 0% exhibited 2.5 cm of growth, 1.25% had 0.9 cm, 2.5% showed 1.2 cm, 3.75% displayed 0.8 cm, and 5% had 0.5cm of growth. As evidenced by the data collected, the height of the sprout decreases as the percent of concentration increases. We checked the growth of our mung bean seeds a second time and we observed the results: 0% exhibited 15 cm of growth showing signs of growth through its stalk, roots, and leaves. The 1.25% and 2.5% both grew 2 cm and began sprouting a stalk. The 3.75% and 5% turned dark brown and appeared to have shrunk which are signs that the seed’s embryo is dead. The data did not match our expected data, because the Miracle Gro had some way prevented the imbibition of the seed which is why the 3.75% and 5% died. Imbibition is a critical developmental process in seeds and our control group with only water demonstrated the most successful amount of growth.…

    Seed Germination EEI

    • 1144 Words
    • 5 Pages

    Germination in plants is the process in which dormant seed begins to grow and sprout under certain growing conditions. The English pea, also known as the garden pea, is a member of the legume family and is known to grow roughly three to four inches long. Research shows that it only takes approximately 1 week for the seed to start to germinate. There are many things that can affect, the growth of the pea seed such as; temperature, moisture, planting depth and sunlight. The pea grows best in temperatures between 7˚C -14˚C, any lower or higher temperatures may affect the seed germination. Often it is recommended for the seed to firstly be planted indoors, where there is a controlled environment. Similar to most living things the English pea needs moister to survive. Pea seeds deprived of water shrivel and die, while those that receive too much water become water-logged and start to decay. Proper watering ensures that the soil around the bases of the pea vines is damp but not saturated, with additional watering scheduled during dry weather.…
