Abstract: The dynamic changes of 7 mineral elements in leaves of hazel were studied. The result showed that in three hazel varieties, the content of mineral elements in leaves were similar in Corylus acellana and Corylu heterophyll Fissch × Corylus avellana , but contents of K,Ca,Fe,Cu were lower in Corylu heterophylla Fisch than the other two varieties. Meanwhile, the variation tendencies of the mineral elements contents were similar in all three varieties. The results of correlation analysis showed that there were antagonist relationship between Zn2+ and Mg2+ and Mn2+ and Cu2+ while there were synergic relationship between Mn2+ and Ca2+, K+and Zn2+ and K+and Mn2+．

Key words: hazel leave, mineral elements, dynamic changes
