The mechanics of explosive dispersal and self-burial in the seeds of the filaree, Erodium cicutarium (Geraniaceae).
The filaree (Erodium cicutarium), a small, flowering plant related to geraniums, possesses a unique seed dispersal mechanism: the plant can fling its seeds up to half a meter away; and the seeds can bury themselves by drilling into the ground, twisting and untwisting in response to changes in humidity. These feats are accomplished using awns, helical bristles of dead but hygroscopically active ...
متن کاملTissue-Specific Response to Experimental Demethylation at Seed Germination in the Non-Model Herb Erodium cicutarium
Experimental alteration of DNA methylation is a suitable tool to infer the relationship between phenotypic and epigenetic variation in plants. A detailed analysis of the genome-wide effect of demethylating agents, such as 5-azacytidine (5azaC), and zebularine is only available for the model species Arabidopsis thaliana, which suggests that 5azaC may have a slightly larger effect. In this study,...
متن کاملIntraspecific variation among clones of a naïve rare grass affects competition with a nonnative, invasive forb
Intraspecific variation can have a major impact on plant community composition yet there is little information available on the extent that such variation by an already established species affects interspecific interactions of an invading species. The current research examined the competitiveness of clones of a globally rare but locally common native grass, Calamagrostis porteri ssp. insperata ...
متن کاملAntioxidative effect of extracts from Erodium cicutarium L.
Extracts from Erodium cicutarium L. (EC) and some standard substances present in EC extracts were tested for their antioxidative properties during Fe(2+)-induced triglyceride oxidation. Hydrophobic fractions such as petroleum ether (PEE), benzene (BE) and chloroform I (ChE I) extracts as well as hydrophilic fractions i.e. water (WE) and ethyl acetate (EAE) showed an antioxidative effect. Among ...
متن کاملSelf-burial Mechanism of Erodium cicutarium and Its Potential Application for Subsurface Exploration
Erodium cicutarium L. plants disperse their seeds by a combination of two dispersal strategies: explosive dispersal, and self-burial dispersal. As the fruits dry, the stresses developed in the structure cause the sudden separation of the seeds that fly away from the plant. Then, once on the ground, the seeds respond to variations in the external humidity : their dispersal unit, is helical when ...
