DailyDirt: Shhh! The Plants Are Listening!
from the urls-we-dig-up dept
- Researchers at the University of Missouri have detected plants creating more defensive chemicals when exposed to the sounds of caterpillars chewing. The scientists measured the tiny vibrations using laser reflections off leaves and noted that playing back other vibrations didn't result in the plants synthesizing more defensive mustard oils. [url]
- Do plants really grow better in response to music? Mythbusters says it's plausible, and a few other studies seem to support this idea. [url]
- Apparently, chili seedlings can detect who their neighbors are -- and distinguish between "bad" neighbors such as fennel and "good" neighbors like basil. One proposal is that these plants can "hear" acoustic vibrations from adjacent plants... but that's crazy, right? [url]
