Scientists study what effect human emotions have on plants

Scientists in Italy are studying what effect human emotions have on plants. Stefano Mancuso, professor of Plant Physiology at the University of Florence, is leading the study. He’s joined with German artist Carsten Höller. Höller said that it’s the first experiment of its kind. The Florence Experiment will have people wear a belt with a bean plant in it. they’ll go down a slide with the belt on. When they reach the bottom, they’ll hand the plant to a researcher, who analyzes it. The sliders will fill out a questionnaire, explaining how they felt during the way down. Researchers will compare the emotions to the plant, using the Licor 6800 instrument. It analyzes different photosynthetic parameters of the plant’s leaves and gas exchanges. “Researchers analyze the photosynthesis—which is the engine, the heartbeat of plants,” said Mancuso. “And then they analyze the Volatile organic compounds, that are messages sent by the plants."
