Wood Identification of Tetracentron Sinense of Endangered Plant
Tetracentron sinense,one of the most important species in our country,enjoys second class protection status on the National Key Protected Wild Plant List.In this paper,the wood names,structural characteristics of wood macrocosm and microcosm of Tetracentron sinense were analyzed.The results showed that the macrostructure of Tetracentron sinense had wider wood rays,which were visible to the naked eye,and it is the basis of distinguishing coniferous wood from coniferous wood that the diameter wall of early wood tracheids is trapezoid with ribbed hole,and the diameter wall is trapezoid and trapezoid with ribbed hole in the transitional part of early evening village.The radial walls of late wood tracheids with ribbed pores are typically arranged in a single row and are rounded.Furthermore,the wood rays widen at the boundary of the growth ring,causing the outer edge of the growth wheel bulges outward along the rays;and the ray-tracheid pinhole types are in alignment,sometimes in alignment-trapezoid or to trapezoid.It provides basis for wood identification of Tetracentron sinense.
