RESEARCHES CONCERNING SOIL PH ON INVASIVE SPECIES FROM GRASSLANDS PUBLISHED

Veronica Sărăţeanu, Alexandru Moisuc
Ecologic and economic impact of invasive species is perceived from local to global level. The purpose of this work is to provide useful pieces of information concerning plant species invasion phenomenon in Romanian grasslands. Researches were realized during 2003-2005 on 38 permanent grasslands situated in places with different environmental conditions from Banat region (western Romania). Grasslands studied in this work show a great soils variety. Thus is quantified the comportment of invasive species under the influence of soil pH. For this purpose here is calculated the correlation considering as dependent variable annual coefficient of grassland surface occupation (spreading coefficient) with invasive species.
