SOTES, GASTÓN J; BUSTAMANTE, RAMIRO O  e  HENRIQUEZ, CAROLINA A. Seedling distribution and seed germination of chilean lucumo (Pouteria splendens) in Los Molles, Chile. Rev. chil. hist. nat. [online]. 2013, vol.86, n.3, pp.337-344. ISSN 0716-078X.  http://dx.doi.org/10.4067/S0716-078X2013000300010.

Pouteria splendens (Chilean lucumo, red wood) is an endemic and endangered tree from Central Chile. It is the only member of the Sapotaceae family in the country and little is known about his life cycle. In this work we described the spatial distribution of seedlings in the biggest remained population of the species, and we investigated the effect of the water availability, presence of pericarp in the seeds and the leaf litter on the capacity of germination in the species. Seedling density was higher under the canopy of mother plants, than outside its. Only water availability had a significant effect on the germination. The species has the potential to regenerate, in future plans of conservation and restoration of the species must take advantage the nurse effect of the canopy.

Palavras-chave : canopy; endangered species; endemic tree; leaf litter; pericarp.
