Ecological role of efectl. Phytotoxicity of Phytolacca americana leaf extracts on the growth, and physiological response of Cassia mimosoides. This proposal is based on ale,opatico idea that plants can release chemicals compounds into the environment, and that these chemicals may suppress the growth and development of other surrounding plants; a process known as allelopathy Inderjit et al. Biological assays were carried out under laboratory conditions, based on aqueous extracts and the direct effect of plant material.


In addition, one of the main recent developments in invasion biology is the recognition that many invasive species affect entire ecosystems, often through modifying nutrient cycles or physical structure EhrenfeldSimberloff Comparison of the allelopathic potential of four march species.

In addition, the relief is from flat to undulating and there is widespread presence of monocotyledonous and dicotyledonous herbs; as well as isolated tree and short stands of A. Biological activity obtained from different parts of A.

The volume of water was chosen based on previous experiments to ensure the minimum amount of water to allow germination. In consequence, it is possible to infer the jeopardizing effect that this invasive species may pose over the native biodiversity on a short and long term basis, as well as to help us aleoopatico understand the mechanisms used by A.
