Abstract: The experimentwas carried out using pot-cultured three-year-old Fuji apple tree (Malus pumila /Malus hupehensis Rehd. ) after cuprum (Cu) and cadmium (Cd) app lied to soil. The content of Cu and Cd in roots, shoots and leaves was measured during the growing season. The results shows that the accumulation of Cu and Cd in roots, shoots and leaves all increases with the increase of the content of Cu and Cd in soil. The content of Cu and Cd in roots and shoots rises step by step from the period of leaf expanding to the period of new shoot growth and gets the peak at the period of new shoot stopp ing growth in spring. The change of content of Cu and Cd in leaves lag behind that in roots and shoots. The content of Cu and Cd in leaves get the peak at the period of shoot growth again in autumn. The order of Cu and Cd content from high to low in different parts of app le is root > trunk > shoot > leaf. Root can absorb more Cu. There are more Cu is accumulated in roots and more Cd is transferred to top.

Key words: App le, Cup rum, Cadmium, Heavy metal, Accumulation
