Abstract: The effects of cadmium（Cd） contaminated soil with different concentrations on the growth of kiwifruit（Actinidia chinensis Planch.） and the accumulation and transfer rule of Cd in kiwifruit were studied by pot simulation experiment. The results showed that the fresh weight, rhizomes diameter, root length and leaf area of kiwifruit were all not significantly affected in the soil polluted by low concentration Cd. In the soil polluted by medium and high concentration Cd, the growth and development of kiwifruit were inhibited, and the fresh weight, rhizomes diameter, root length and leaf area were all decreased, and the growth was more severely inhibited with the higher concentration Cd; with the increase of soil Cd concentration, the absorption capacity of kiwifruit leaves increased but the enrichment capacity remained unchanged, the absorption capacity of kiwifruit stems increased but the enrichment capacity first decreased and then increased, and the absorption capacity of kiwifruit roots increased but the enrichment capacity first decreased and then tended to be stable; with the increase of soil Cd concentration, the transfer coefficients of kiwifruit first decreased and then tended to be stable, and the transfer coefficients were all less than 1. The heavy metal Cd was mainly enriched in the roots of kiwifruit. Under the conditions of different concentrations of Cd pollution, the enrichment coefficients of the roots, stems and leaves of kiwifruit were root > stem > leaf.

Key words: kiwifruit（Actinidia chinensis Planch.）, cadmium（Cd）, enrichment coefficient, transfer coefficient
