Dispersal mechanisms in some reprentatives of the genus Moehringia L. (Caryophyllaceae)

Description

The function of diaspores in Moehringia genus was investigated and field observations pointed out the elaiosome role in seed predation and dispersal by ants. Histochemical stainings underlined the presence of lipid in the strophiole. Our results are congruent with the hypothesis that some representatives of the genus Moehringia adopt myrmecochory, especially those species that prefer rocky habitats. Strophiole dimensions and oil content volume seem to influence seed predation in plants by ants. However, the interaction of further abiotic dispersal agents (wind, water) may increase and make more efficient the dissemination strategies
