Recently, phytoremediation has been interesting world widely. For example, low price, easy maintenance, suitable for cleanup wide area. This study was aimed to evaluate Ajuga reptans L. as a phytoremediator removing Cd contamination. 1ppm, 10 and 100ppm Cd concentration effects measured during 7days. Cd uptake increase according to Cd concentration level high in hydroponicaly cultivation in general. Uptaked Cd measured in the rhizosphere and shoot of Ajuga reptans L.. Measured Cd concentration in rhizosphere and shoot are 3,607.7mg • kg&sup-1; and 289.5mg • kg&sup-1;. Root high and shoot low Cd concentration ratio was maintained according to increasing Cd level. Therefore, Ajuga reptans L. remove the Cd contaminations can be considered meaningfully.
