Abstract
Effects of different concentrations of Cd2＋ on growth of Populus 2025 （Populus xeuramericana）and its enrichment were investigated. The results indicated that the growth of Populus 2025（Populus×euramericana）was inhibited significantly at 100-500 μmoL/L Cd2＋. Enrichment of Cd2＋ increased with concentration of Cd2＋ increased and prolonging treatment time passed. Cd2＋ was mainly accumulated in roots. Cd2＋ contents were significantly higher in young leaves than that in mature leaves. Levels of Cd2＋ accumulation of Populus 2025 （Populus xeuramericana）were in the order as follows ： barks 〉 stems 〉 woods.关键词
