Abstract: Tectona grandis L. f. is a kind of defoliated or half-defoliated tall arbor,belonging to Verbenaceae Tectona. In this softwood cuttings propagation experiment the half-lignified twigs of 4-year-old Tectona grandis L. f. were treated with powder in different concentrations in the last ten}lay of July. The anatomical between structure exogenesis hormones of IBA of rhizogenesis tissues of the softwood cutting propagation were cutting woods rooting and callus,primordium of adventitious roots,and to studied,to discuss the relationship study the type and process of adventrtrous roots.
