%X High-frequent transformation and strong regeneration ability of plants are prerequisites to the establishment of good plant transformation receptor system, which is the foundation for plant genetic transformation. Taking 84K poplar leaves as study material, this experiment studies the influence of different types and concentrations of plant hormones to its dedifferentiation and re-differentiation under different cultivation conditions, and sets two mature plant tissue cultivation regeneration system. Based on above,here establishes genetic transformation system of adventitious buds and callus pathway, respectively as callus regeneration system and regeneration system of direct differentiation. Then through conducting comparative analysis of two tissue culture system using <i>PCK1</i> and <i>PCK2</i>, here summarizes the advantages and disadvantages of two methods.
