%X Abstract: Calli induced from seedings of rice (Oryza sativa) were subcultured in MS medium containing different tested plant growth hormones. The combination treatment of 2 ppm 2,4-dichlorophenoxyacetic acid and 1 ppm kinetin is most effective in production of tiny, white and hard calli, which contains 8% cells being tracheary elements in shapes of fork, nodule and band. Ultrastructural studies show the appearances of gradually degenerated organelles and unevenly wall-thickening occurring in differentiating tracheary elements. Mature tracheids contain only cell wall with distinct and unevenly thickened secondary wall, and partially remained primary wall.
