Transcript of Seed Germination
- 45 Pinto beans
- Paper towels
- Water (24 mL in cups G,H,I) (12 mL in cups D, E, and F)
- Hydrogen Peroxide (24 mL in cups A,B, and C) (12 mL in cups D,E, and F)
- 9 plastic cups
The purpose of the project is to see if something other than water can aid in plant growth. With that said, we chose hydrogen peroxide because it is similar to water and we wanted to see if it would still work on plants. The reason it would be beneficial to have something other than water to use on plants is to see if there would be something to speed up the process of plant growth or even work better than water.
Background Info/ Intro
The topic of this project is the effects of hydrogen peroxide on pinto bean germination. Many scientists have done the similar project as we have and we came across many different ways to test how hydrogen peroxide effects pinto bean germination. One of the experiments was by a college professor, Kudret Kabar (2010) who studied the germination of seeds and the most important factors of seed germination and concluded that the germination of a seed is the most crucial stage in the life cycle of a plant. Due to the stress that a seed undergoes the germination process can often become very difficult, and the success of the seed’s germination under difficult conditions could enhance its chance to continue growing and developing after germination. With that said, we designed a project of our own to test how hydrogen peroxide affect plant growth.
If the concentration of hydrogen peroxide affects pinto bean germination, and if we design an experiment in which pinto beans are subjected to various amounts of hydrogen peroxide and water, then the higher the water concentration, the higher the rate of pinto bean germination.

First, we placed 9 cups with 5 seeds in each cup, under the 5 seeds was a paper towel as well as over the seeds. We then labeled the cups as cup A, B, and C which pertained to the cups that recieved H202, cups D, E, and F as controlled, and cups G, H, and I as both. We water each cup with their appropriate solutions for 5 days. Cups A, B, and C will get 24mL of hydrogen peroxide, cups D, E, and F will get 24mL of water, cups G, H, and I will get 12mL of water and 12 mL of hydrogen peroxide. For five days we will daily count how many seeds in each cup has germinated.
This was the day we created our project
We started the project on 3/24 which was the first day that we watered all the plants . We checked the plants the next day, 3/25, and none of them had germinated. On 3/26, cups A-C (h202) had 9/15, Cups D-F (controlled) had 11/15, Cups G-I (both)had 8/15. On 3/27, Cups A-C had 11/15, Cups D-F had 13/15, and Cups G-I had 12/15. On 3/30, the number of seeds gemrinatd in each cup had not changed. On 3/31 (the last day of watering). cups A-C had 14/15, Cups D-F had 15/15, and Cups G-I had 13/15.
In the end, the cups with the hydrogen peroxide in them were also growing, but not as rapidly as the seeds with only water. So with our research w
e concluded that when hydrogen peroxide is added into the water mixture, there is not a significant difference in the germination process of the plants. Hydrogen peroxide comes in many different forms; these forms vary by percentage of concentration. The higher the percentage, the stronger the hydrogen peroxide will be. The type of hydrogen peroxide we used in our experiment was 3%, which is most commonly used for everyday purposes. (i.e teeth whitening, disinfecting, etc) After doing research on using hydrogen peroxide gardening, we found that hydrogen peroxide can actually be very beneficial for a developing plant.
