- Research Title: What is this experiment about? Make sure that it is clear and concise
The experiment is about the role of tomato juice in influencing the rate of seed germination in plants. The experiment shall enable one to understand the basic requirements for plant growth.
- Research Objective
The research objective for the current experiment is:
- Hypothesis: What are you testing in this experiment?
The hypothesis statement for the current experiment is: Tomato juice has a negative impact on the rate of germination in plants. The experimental group is seeds germinated in medium with tomato juice and the control group is seeds germinated in water.
- Prediction: What results do you expect and why do you expect them? You should provide a somewhat detail explanation of why you expect certain results.
It is expected that seeds that are germinated in tomato juice should have a negative germination rate in comparison to the seeds germinated in water. Research studies have suggested that plant hormone Abscisic Acid (ABA) in the tomato fruit may be responsible for inhibiting the seed germination. ABA may prevent the production of RNA and growth proteins that are required for the germination of seeds.
The presence of tomato juice medium has a positive impact on the rate of seed germination. Tomato juice is used as a supplement medium for the germination of seeds and it has been observed that tomato juice has a tendency to support maximal seed growth .
Water is considered as one of the most important factors for seed germination. Water plays an important role in germinating the seed by softening the seed coat so that roots can emerge easily . Water also combines with stored foods in seed to form soluble forms of nourishment for the seed. Water also helps to enlarge new cells and serves as a medium of food transportation in the seed .
- Proposed Methods
The materials required for this experiment include seeds, paper towels, water, tomato juice, plastic bottle and ruler. 10 seeds are selected as the variable and 10 seeds are selected as control. The seeds are placed on a paper towel at the bottom of the plastic bottle. Two different plastic bottles are used in this experiment each for control and variable. Each paper towel is dampened with the liquids water for control and tomato juice solution for variable. The percentage of seeds that germinate each day are recorded for a period of 7 days. After data collection, the data is plotted the percentage of seeds germinated in tomato juice and water.
- Results
- Discussion
Water is a necessary condition for the germination to take place. The increase in the concentration of tomato juice has a positive impact on the rate of germination. This is due to the fact that tomato juice provides the supplementary nutrition in addition to the endosperm in seeds and with the increase in pH from acidic to alkaline, the rate of germination increases.
Research studies have suggested that plant hormone Abscisic Acid (ABA) in the tomato fruit may be responsible for inhibiting the seed germination. However, in the case of tomato juice, the level of Absissic Acid cannot account for an inhibitory effect on seed germination .
