Rapid plant movement

Rapid plant movement

Rapid plant movement encompasses movement in plant structures occurring over a very short period of time, usually under one second. For example, the Venus Flytrap closes its trap in about 100 milliseconds. [Forterre, Y., J.M. Skotheim, J. Dumais & L. Mahadevan 2005. PDFlink| [http://www.oeb.harvard.edu/faculty/dumais/Publications/Nature2005.pdf How the Venus flytrap snaps.] |318 KiB "Nature" 433: 421–425. doi|10.1038/nature03185] The Dogwood Bunchberry's flower opens its petals and fires pollen in less than 0.5 milliseconds. The record is currently held by the White Mulberry tree, with flower movement taking 25 μs, moving petals to velocities in excess of half the speed of sound- near the theoretical physical limits for movements in plants.Taylor, P.E., G. Card, J. House, M. H. Dickinson & R.C. Flagan 2006. High-speed pollen release in the white mulberry tree, "Morus alba" L.. "Sexual Plant Reproduction" 19(1): 19–24. DOI|10.1007/s00497-005-0018-9]

These rapid plant movements differ from the more common, but much slower "growth-movements" of plants, called tropisms.

Charles Darwin in 1880 published his last work before his death, "The Power of Movement in Plants".
