Raíces adventicias de Saxegothaea conspicua Lindl. (Podocarpaceae) en su etapa de senescencia en bosques adultos

Resumo

We studied the anatomy of the adventitious structures that Saxegothaea conspicua Lindl. develops inside of the stem during its senescence stages in old-growth temperate forest; by scanning electronic microscopy, we evaluated the hypothesis whether those structures correspond to adventitious roots. The results confirm that the anatomical structures are similar to a common roots system at first development stages. We discuss the possible functional implications of these adventitious roots in extend the life of the individuals in forests.
