serenading your plants • AS MEASURED on their second day after fully opening, the average blossom size was 2.13 in. for those exposed to Vedic chants, 2.12 in. for those exposed to Indian classical music, 1.92 in. for those exposed to silence, 1.85 in. for those exposed to Western classical music, and 1.46 in. for those exposed to rock music. Additionally, the researchers in this study noted the plants that were exposed to the chants grew towards the music, while the ones exposed to rock tended to grow away from the music source. The ones that were exposed to rock music also developed thorns first and had the highest average amount of thorns compared to the other groups. A separate two-year Egyptian study, published in 2017 in the Life Science Journal, looked at growth rates, oil production, and pigment variations on salvia plants that were exposed to Western classical, jazz, and silence. The researchers also found that the type of music a plant is exposed to makes a big difference in the data. They looked at total plant height, number of branches per plant, fresh and dry herb weights, percentage of oil and oil yields per plant, and the amounts of total chlorophyll and carotenoids in each plant. With very little exception, the plants exposed to the classical music outgrew and outyielded those exposed to jazz or those that grew in silence. Here are their observations: • THE PLANTS exposed to classical music had the most amount of vegetative growth in both years of the study. Year one averages were 14.96 in. compared to 14.17 in. for those in silence and 13.39 in. for those exposed to jazz. “ THE ONES THAT WERE EXPOSED to rock music also developed thorns first and had the highest average amount of thorns compared to the other groups.” 44 feature Year two followed suit, with the ones listening to classical music reaching an average of 15.31 in., while the ones exposed to silence and jazz music reached only 14.57 in. and 13.9 in., respectively. • THE PLANTS exposed to classical music also had the highest average number of branches per plant over both years of the study. They averaged 33 branches per plant in year one and 34 in year two. Plants exposed to silence averaged 30.6 and 31 branches per plant over years one and two, respectively. Plants exposed to jazz music averaged 27 branches in year one and 28 branches during year two.
