An article on how
sound plays a part in plant-plant communication and plant-insect communication, not always beneficially from the plant's point of view.
And there is evidence that insects and plants "hear" each other's
sounds. Bees buzz at just the right frequency to release pollen from
tomatoes and other flowering plants. And bark beetles may pick up the
air bubble pops inside a plant, a hint that trees are experiencing
drought stress.
Implications for drought:
In the arid Southwest, [Duke University botantist Dan] Johnson was surprised to find that the plants
considered the most drought-tolerant, such as junipers, did worst at
repairing embolisms. Broad-leaf plants, including rhododendrons and
beaked hazels, were better at fixing the damage caused by dry pipes.
