Popis:	In the beginning of the spring Aristotelia chilensis sheds the old cohort, forms a new one and flowers. Fifteen days before the flowering and the fall we measured net photosynthesis (A), transpiration (E), water use efficiency (WUE), specific leaf mass (SLM) and area and mass of leaves per branch in old and new cohorts. Under low irradiance the old cohort exhibited higher mean values of A and WUE on area bases (PNo início da primavera Aristotelia chilensis perde as folhas da cohort mais velha, forma uma nova cohort e floresce. Quinze dias antes da floração e perda da cohort velha medimos: fotossíntese líquida (A), transpiração (E), eficiência do uso da água (EUA), massa específica da folha (MEF) e área e massa das folhas por ramo nas cohorts nova e velha. Sob baixa radiação a cohort velha apresentou valores médios maiores de A e EUA expressos em área (P
