Abstract

Allelopathic aspects in Rumex crispus L. and Rumex obtusifolius L. I. Allelopathic effect on grassland grasses.

Abstract

Rumex species have a wide variability and a large phenotypic plasticity depending on the environment. In general, these species are considered invasive because of the high degree of grassland, perennial legume, and annual crop infestation. Literature values the allelopathic effect of these species due to phytotoxic substances in almost all plant organs. This paper points out the allelopathic effect of two Rumex species (R. crispus and R. obtusifolius) on seed germination capacity in some grassland grass species.
