The aim of this study was to investigate the developmental physiology sweet chestnut trees (Castanea sativa Mill.) different age groups (≥ 25, ≥ 50, 100, 200, and 400) in Catalzeytin district Kastamonu, Turkey. For purpose, photosynthetic pigments, proline, total soluble protein, glucose, sucrose, carbohydrate starch values, malondialdehyde (MDA) hydrogen peroxide (H2O2) concentration, also ascorbate peroxidase (APX), catalase (CAT), superoxide dismutase (SOD) activities were measured leaf samples. Hence, significant differences found amounts concentrations all types chlorophyll, carotenoid, carbohydrate, starches, MDA, H2O2, APX, CAT, SOD among groups. While chlorophyll a value low young trees, b older trees. It determined that MDA content high old whereas it highest 400-year-old they lowest Both APX CAT activity
