From Wikipedia, the free encyclopedia
Resin canals, or Resin ducts, are elongated, tube-shaped intercellular spaces surrounded by epithelial cells which secrete resin into the canal. These canals are orientated longitudinally and radially in between fusiform rays[1]. They are usually found in latewood: denser wood grown later in the season[2]. Resin is antiseptic and aromatic and prevents the development of fungi and deters insects.
