  1. Trial Averages % of Seeds Germinated

  2. Observations- Day 2

  3. Observations- Day 6

  4. Summary of Results • Germination rate was the highest when no magnetic field was present • Germination rates were similar for the 2 magnet and 4 magnet case • Although the germination rate was similar for these 2 cases, plant growth was more extensive when the magnetic field strength was lower • Seeds with 6 magnets were negatively affected by the magnetic field and had a very low germination rate

  5. Theories • Researchers have reported contradictory results on plant growth, some showing positive growth benefits, and some showing negative • Effects appear to be species specific • The exact mechanisms of how magnetic fields affect plant growth are unknown, but two theories are: • Magnetic fields influence the uptake and transport of Ca++ which are important in many plant growth processes • Magnetic fields interfere with hydrogen bonding in water which can influence water uptake during germination

  6. Further Experiments • Test the calcium ions in the radish seeds by using a staining process that would reveal the calcium ions in the radish cell • Dissect the germinated seeds and examine them under an optical microscope to determine any structural changes
