• Resumen

  • 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.
