Résumé
Thlaspi caerulescens, an indicator of soil pollution? Can the existence and the density of particular plant species give several informations about the degree of soil pollution? After having chosen different sites for this survey, the identification of collected plant species and the soil characteristics of collection sites were compared and some correlations were established. Data on growth of collected plants indicated the existence of two ecotypes of Thlaspi caerulescens. It has been shown the preference of one of the ecotypes for the metal-contaminated soils.
