Research on the Distribution of Resin Canals of Cedrus deodara Based on Wood Anatomy

Abstract:

Whether the resin canals of Cedrus deodara are caused by injuries is still controversial. In this paper, with the branches and trunks of Cedrus deodara taken as research objects, the resin canals in the phloem and xylem of Cedrus deodara are quantitatively and qualitatively analyzed and researched with the principles of wood science, aiming at exploring whether its distribution provided with regularity. The results showed that several parts showed relative stability, such as the morphological characteristics, anatomical structure, occurrence time, cellular component and quantitative characteristics and so on. In terms of occurrence probability and quantities, the resin canals generally occurred in the compression and lateral zones of branches while few in the opposite zone; the occurrence of the resin canals of trunks had an extremely close tie with the growth and insertion angle/direction of the branches of different areas and directions, etc. Therefore, from the perspective of formation time, Cedrus deodara belongs to the tree species with slowly-formed resin canals.
