Strawberry (Fragaria x ananassa Duch.), cvs Senga Sengada and Elsanta was grown in two types of soil: A- light and B- heavy. Both soils were contaminated with 0, l or 2 mg Cd/kg. After 12 weeks of plant growth concentrations of low molecular weight organic acids (LMWOAs) in the rhizosphere soil and cadmium in roots were determined. Oxalic, malonic, fumaric, succinic and maleic acids were found in the rhizospheric soil of both cultivars. Oxalic acid was the most abundant. Soil contamination with cadmium stimulated the production of LMWOAs and increased Cd content in strawberry roots. Cadmium content in roots of Elsanta cultivar was higher when grown after Cd treatment in soil B as compared to soil A
