Seed germination is the beginning process of which a plant embryo begins to grow and develop. For most circumstances a flowering plant needs exposure to light, oxygen, and water to germinate. The experiment conducted will test the ability of radish seeds to germinate in a controlled environment and in a bleach solution.
• Petri dishes
• Filter paper
• Radish seeds
The petri dishes were each given a piece of filter paper and ten radish seeds were placed inside. The petri dishes were then closed. One dish was given regular water and was set on a window sill for exposure to sunlight and the other was given a bleach solution and was set on the same window sill. The seeds were then left to germinate. Each day the seeds were checked to see if they were still getting the water and sunlight they needed. Nothing else was done to the seeds.
After a week, the seeds were observed to see how many had germinated in each dish. The graph below shows the numbers of seeds in each dish to have germinated.
The control seeds germinated all 10 seeds. But in the second dish none of the seeds germinated.
The bleach in the dish seemed to have killed the radish seeds and completely stopped the germination process. The hypothesis would have to be confirmed that the bleach would hinder the germination process of the seeds. This results means that any sort of chemicals like bleach, or with the pH of bleach could possibly harm radish populations if it were to be introduced into the area where the seeds were trying to germinate.
