Volatile organic compounds (VOCs) are emitted from wounded plants as a defensive mechanism, slowing the growth of the plant. They can also signal proximate plants that wounding has occurred and induce the production of defense-related compounds. This experiment looked at whether VOCs from wounded grass grown near bean plants slow the growth of the bean plants. The growth rate of bean plants grown next to unwounded grass was compared to the growth rate of bean plants grown next to wounded grass. This may affect where gardeners or farmers place their plants or crops so as not to stunt their growth.
