Summary Thirty four plant species belonging to 9 families were grown on a sand soil with various levels of added Cd. The Cd content of aerial parts of the plants (tc) was correlated to the soil Cd level (sc) in a double-logarithmic relationship: log (tc)=α+β log (sc). The regression coefficients α and β statistically differed among plant families. Plant families were classified into 3 groups based on the α values; (1) low accumulation, Leguminosae; (2) moderate accumulation, Gramineae, Liliaceae, Cucurbitaceae and Umbelliferae; and (3) high accumulation, Chenopodiaceae, Cruciferae, Solanaceae and Compositae. Values of β also enabled to discriminate the families into (1) Umbelliferae, Cucurbitaceae and Cruciferae in which Cd accumulation was promoted at higher soil Cd levels, and. (2) the other families which were of the excluder type.
