[Anatomical and cytohistological changes caused by aqueous extracts of Tamus communis L. leaves].

Aqueous extracts of Tamus communis leaves induce root tip swelling of Medicago seedlings and disrupt the mitotic process of Allium root tips. The cells of the swollen roots of Medicago treated seedlings are much wider an shorter than the homologous control cells. In the treated roots of Allium prophases prevail and some cells contain vacuolated nuclei or micronuclei.
