Factors Affecting Seed Germination Lab

All five groups recorded the outcomes that they established. For our bench, we found that nine raddish seeds in the control dish, zero raddish seeds in the eucalyptus dish, and four radish seeds in the lemon dish germinated and sprouted. Our bench also found that the average seed length for the control was thirty one millimeters, for the Eucalyptus was zero. and for the Lemon was eight and a half. Below, is a chart and graph that shows the whole data as averages from all five benches. Each bench did the exact same experiment so we knew nothing would be biased.

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

Before, I started I made a prediction for the experiment. I thought the salt on top of the seed and inside the paper towel would soak up water and dehydrate the seed and make the paper towel go dryer

The ravg for the experimental group was 0.1613 and the ravg for the control group was 0.2047. The results indicated that our predictions were correct; duckweed that received less light exhibited a lower rate of

10. Clean out the petri dish using water and a paper towel. Put a new mound of mystery powder on it, then drop about five drops of vinegar onto the mystery powder mound using a pipette. Record observations.

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.

Add three seeds to the potting mix and cover seeds with little remaining potting mix. After the addition of the potting mix, use a dropper filled with water and water each cell until water drips from the wick. Then place the quads on a watering tray under the fluorescent light bank. Each cell should have an equal distance from the light bank. Quads should be three inches below the fluorescent light; the light should also be left on all day. Make sure all wicks are in contact with the mat that sits on the watering tray. Also watch out for the watering system regularly throughout the experiment. After four to five days record plants in the quads, giving their phenotypes in a table for each cell removed all but the strongest plant.

METHODS/PROCEDURES: In the beginning of the experiment, pea seeds were used in order to perform the experiment. It was extremely important to acquire good, dry, and viable seeds so the process of germination could occur. A handful of these healthy seeds worked best in assisting the experiment. The seeds ability to germinate was a vital information needed to determine the outcome of the experiment.

3. For the most part, the design of our experiment was pretty good. One weakness I think we had was our constant. I think we would have had a better constant if the seeds in the Natural Light category were actually outside,

8. Use a hold puncher to cut 10 leaf disks for each cup. Avoid hold punching around the ribs of the leaf.

This experiment was performed using the procedure from the Photosynthesis in Leaf Disks Lab. First using a #3

1. Allow the seeds to germinate for three days prior to the experiment. Prior to the first day,

This lab was a success, because it shows what happens with acid rain, and its effect on seed germination. The seeds will actually grow

It is a fact that almost all plants need light in order to grow and maintain health, but is it true that all plants need light in order to germinate? It is also a known fact that most seeds are chosen by producers based on how easily they germinate, as well as other characteristics. Augustus Braun Kinzel performed an experiment in 1926 in which he found the light requirements for hundreds of different plant species. For example, he found about 270 species that germinated in the light (at the same temperature), and about 114 that germinated in the dark (at the same temperature). His experiment showed us that not all seeds within the same genus respond to light in the same way.
