Resin canals are structures within plants that contain a resinous substance. Synonyms for resin canal include resin duct, gum duct, resin passage and oleoresin canal. These canals are typically found in coniferous trees such as pines and spruces, as well as in some angiosperms such as the Hevea brasiliensis tree which produces latex. The function of resin canals is to transport and store resins, which can act as a deterrent for herbivores, protect against microbial infections, and aid in wound healing. Understanding the different synonyms for resin canal can help researchers and botanists better understand the specific structures and functions within plants.
