Erodium ciconium. New England Distribution (18 Photos)


When several references are cited, they may give conflicting information on the status. The shape of the awns change from straight to helical, causing them to explosively separate the seeds away from the maternal plants. Aiton, Hort. Please consider upgrading your browser. As the fruits dry, dehydration create tension, and elastic energy develops within the awns. The energy storage capacity of the seeds is determined by the level of hydration, suggesting a role of turgor pressure in the explosive dispersal mechanism. Search on:.

Inversely, the matrix will contract under dehydration, leading to the coil of the awns. When several references are cited, they may give conflicting information on the status. Two techniques that Erodium uses are explosive dispersal which launch seeds by storing elastic energy, and self-burial dispersal where Erodium seeds move themselves across the soil using hygroscopically powered shape change. As the fruits dry, dehydration create tension, and elastic energy develops within the awns.
