Leaf phenology and its associated traits in the wintergreen species Aristotelia chilensis (Mol.) Stuntz (Elaeocarpaceae) RChHN
DAMASCOS,MARÍA ANGÉLICA; PRADO,CARLOS HENRIQUE B.A..
The post-summer leaf demography of the wintergreen species Aristotelia chilensis growing near San Carlos de Bariloche, Argentina, is described. Its specific leaf mass (SLM, g m-2) is compared to that of the deciduous and evergreen species of the Andean-Patagonian forests and to that of other communities abroad. The pattern of leaf emergence is intermediate, with leaf flush in spring (basal cohort, BC), followed by successive unfolding of the remaining leaves (distal cohort, DC) during summer. The senescence of the BC occurs mainly in autumn, with a loss of 11-31 % of its SLM. The DC falls synchronously in mid-spring and the SLM loss in winter is 10-13 %. The SLM of A. chilensis (103.6 ± 6.2 g m-2) is intermediate when compared to the general mean values of...
