Transcript of The Effect of a Magnetic Field on Brassica rapa Plants

By: Samer Salameh and Mohammad Kanny
1862: Louis Pasteur discovered that magnetism had a stimulating effect on plant growth.
1950: Dr. Albert Roy Davis – the man who discovered the existence of north and south magnetic poles and established the study of bio-magnetics – received a patent for magnetically treating plants.

New Advantages Were Discovered:
Accelerated germination and sprouting
Increased protein biosynthesis
Enhanced root development
Greater stem elongation
The Brassica rapa species was selected for experimentation

The Brassica genus includes many of the important agricultural crops that humans eat in their daily lives.

Data Collection and Analysis
The Effect of a Magnetic Field on Brassica rapa Plants

Accordingly, magnetic treatment has become a common agricultural practice in numerous countries, especially Israel.
Advantages of Using Brassica rapa Species:
Need 1-2 days to germinate after planting
Grow very rapidly
Can be provided by the lab
Plants that are treated with a magnetic field absorb greater amounts of water and minerals due to greater cohesion force in the water (induced by the field), as well as more effective root penetration.
Furthermore, this triggers certain hormones (auxins/cytokinins) to proliferate causing enhanced growth and health.
The treatment of Brassica plants with a magnetic field will increase their growth rate and size.
If the results do not validate the selected hypothesis, then the magnetic field treatment clearly would not have produced the desired effect.
The reason for this would most probably be that the magnetic field’s influence would have been negligible relative to the Earth’s magnetic field.

Three different treatments will be implemented (control + two magnetic fields of different strength measured in Tesla), and each treatment will be used on two separate pots.
Each treatment will consist of two sets of four Brassica plants, with each set planted in a different pot.
Hence, each treatment will be applied on eight plants that are equally divided into two different pots, so that results can be properly corroborated.
All plants will be placed under the same living conditions (water, light, temperature etc…), but certain factors will be randomized such as location and direction of light. This randomization minimizes any bias that could skew the results.
1) Prepare 6 pots by adding soil to form the soil bed 10 cm deep (+/- 0.05 cm)
2) Plant 4 Brassica seeds in each pot (cross shape formation)
3) Lower magnetic field: Add 2 magnets (0.03 Tesla) to two pots
4) Higher magnetic field: Add 2 magnets (0.05 Tesla) to two pots
5) Place the pots in different locations of a room. Each plant receives light from a table lamp placed 10 cm away, and directly above the pot.
6) Water the plants 20 mL each day.
7) Record the daily height of each plant for 2 weeks.

Control Factors:
All plants are placed in the same room
Room temperature 22°C
Each pot receives 8 hours of light per day (table lamp)
Each pot receives 20 mL of water per day

Referring to the collected and interpreted data, it is evident that our hypothesis and predictions have been validated.
Plant growth increased in rate and size (indicated by the graphic trends) as the magnetic stimulus was increased.
Furthermore, growth was directed toward the magnetic field. Thus, magnetism induces a positive tropism.

The lack of natural light (due to climate/location) forced us to use artificial light, which is sufficient but not ideal for these plants.
The same can be said about our magnetic field, which was a homemade coil of magnetic tape.
Additionally, the surrounding environment (pots/storage room) does not provide natural stimuli that were overlooked including various minerals and fungi.
Hypothetically, a larger budget would allow our experiments to take place in a more suitable environment such as a greenhouse.
We could expand our research to stronger magnetic fields and explore the effects of electromagnetic fields.

Studies by mineral engineers in the aforementioned country have proven that magnetism lowers the surface tension of water, which increases water solubility and penetration and triggers greater root growths.
Data Interpretation
The presented data shows trends that support our hypothesis and predictions.
The final size/height of the plants was increased by increased magnetic treatment
The results support the prediction that the growth rate would be increased by magnetic treatment.
The low standard deviation and uncertainty in the results (expressed in error bars) supports the credibility of the results in validating our hypothesis.
