Abstract: Twelve eggplant （Solanum melongena L.） materials were planted in cadmium-contaminated soil by pot experiment to study the biomass and cadmium （Cd） accumulation characteristics at the seedling and flowering stages. The results showed that there were obvious differences between eggplant materials on biomass and Cd content. The biomass in root, stem, leaf and shoot of the material XN-Z1-2 were all higher, while that of the material “43-1” was relatively lower;the Cd content of different organs of material XN-Z1-2 was lower but that of the material “43-1” was all the highest when eggplant was at the seedling stage. Overall, the biomass of each organ of the material “96-2” was higher and that of the material “43-1” was the lowest; the Cd content was the highest in various organs of the material “43-1” and generally lower in the material ZF-Z1-2 if eggplant was in the flowering stage. In conclusion, “43-1” was a kind of eggplant material with high Cd accumulation; the material XN-Z1-2 and ZF-Z1-2, all possessed higher biomass and lower Cd accumulation, were eggplant materials with low Cd accumulation which could grow normally in Cd-contaminated soil.

Key words: eggplant （Solanum melongena L.）, cadmium stress, biomass
