Resin canal

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 late wood: denser wood grown later in the season.^[2] Resin is antiseptic and aromatic and prevents the development of fungi and deters insects.
