Suppressive Effect of Some Forage Plants on the Growth of Ambrosia artemisiifolia and Iva xanthiifolia

Abstract

A pot trial in greenhouse conditions has been carried out to investigate the role ofsome plant species in suppression of Ambrosia artemisiifolia and Iva xanthiifolia growth.Screening of several plant species (Medicago sativa L., Lolium perenne L., Dactylis glomerataL. and Elymus repens (L.) Gould – all from both turf and seeds) was conducted. Theresults of the experiment showed that some perennial plants, especially L. perenne, D.glomerata and M. sativa, can be a reliable means of suppression of the growth and seedproduction of A. artemisiifolia and I. xanthiifolia. Moreover, simple greenhouse screeningturned to be a reliable method for predicting this potential suppressive role under certainconditions.
