Abstract：The macro structure，micro structure and cell morphologyof the Dalbergia cultrata wood were measured and analyzed byusing zoom stereromicroscope，digitalmicroscope and image measuringanalysis system，and the wood density was determined at the same time. The results showed that the wood color of the D . cultrata wood was purple red; the growth rings were obvious；the woodwas scatered with holes，andthecombinationtypeof the wood vessels was mainly single vessels，afew were radial multiple vessels，and the shape of the vessl cells was mainlydrum-shaped；the wood fiber cells were superimposed，with smallcavityand thick，and thecellength-width ratioandwallcavityratio were 48.84and O.81，respectively.The xylem rays were fine，imposed，and homomorphic 2-3 columns，withaheightof 5- 9cellsandalength-widthratioof 5.17.Theaxial parenchyma wassuperimposed，abundant，wing-shapedorconcentric paratrachealbelt-shaped;thecellength-width ratio was 6.36.Crystallinecells were mostlydivided intocompartments containingcrystals，with as manyas17crystalline particles.The wave patern was slightly visibleunder the eye；the wood grain was straightand the structure was fine.The woodfiberand crystalcellsaccountedforthe largestand smallst proportionof the wood tissue percentages，respectively；the wood tissue percentages coulddeeply understandthe growth of trees and the propertiesof wood.The wood density was large，andthe density，air-dried densityand oven-dried density of the wood were 0.85，1. 04， 0.94g/cm3 ，respectively. The above analysis perfected the theory of wood anatomical structure and provided theoretical basis for wood identificationand appraisal.
