Not only has music been proven to affect humans, but also the growth rate of plants. According to previous studies, it can be concluded that two types of music, positive music and negative music, can either help plants grow faster or it can kill the plants respectively. The purpose of my project was to find out whether plants infected with Tobacco Mosaic Virus (TMV) had the same growth rate effect as healthy plants when exposed to music. Five groups of bean plants were planted. After 10 days, when plants had four true leaves, 2 groups of plants were inoculated with TMV and were then exposed to positive or negative music. 2 other groups were not infected whatsoever but were exposed to positive or negative music. The control, the fifth group, was neither infected nor received any music. The results showed that infected plants had the same outcome as healthy plants exposed to music. The plants with positive music showed that they grew more than the control as well as the plants exposed to negative music. The plants exposed to negative music had the least amount of growth and showed signs of wilting leaves.
