To elucidate the relation of leaf development stage to the antioxidative function in leaves of Alnus firma Sieb. et Zucc. growing in polluted areas, we investigated seasonal changes of pigment content and antioxidant enzyme activities from January to June. In abandoned mine and industrial complex areas, antioxidant function against stress of trees was changed with leaf expansion, and antioxidant activity in leaves was highest in June. Among antioxidants, carotenoid, SOD and CAT were correlated with seasonal change.
