The Effects of the Magnetic Field on Primary Carrot Roots

Kruti Sanghavi, John F. Kennedy Memorial High School, Metuchen, NJ

Abstract: The Magnetic Field is a factor that influences all living things. It is an environmental factor that has been important to all living organisms through out time including plants. The magnetic field is closely related to the cell metabolism of the plants (Belyavskaya, 2004). Magnets have 2 opposite poles. The effect of these different poles on root growth has not been studied. The two poles of a magnet each have a different effect on different kinds of roots. Taproots are roots that have a positive magnetic tropism. It is not certain which pole has a more significant and positive effect on the growth of taproots. Four different groups of carrots seeds were planted and grown in four Root-Vue chambers, where the growth of the roots could be monitored and measured. Magnets were placed so that the roots were exposed to different magnetic poles. The steel bar magnet was placed in between two roots, where each root was placed 4cm away from the magnet. The control did not use a magnet. Plants were grown for 21 days and results on root growth length were calculated. The T Test was conducted for statistical analysis, and it proved to be not significant. The P values for the Control vs. North Pole was 0.4724, Control vs. South Pole was 0.4172, and the North Pole vs. South Pole was 0.9155. The results proved to be not significant, and did not have a great difference in the growth rates of the three groups.
