[Objective] The research aimed to study the differentiation morphology and its relationship between vegetative growth of Zinnia elegans 'Dreamland'.[Method]The paraffin section of Z. Elegans 'Dreamland' terminal bud in different period was observed.And the growth index of Z. Elegans at each time (plant height,crown diameter,leaf number,days after seeding) was determined.[Result]Flower bud differentiation process was divided into 8 phases: vegetative growth prophase,vegetative growth anaphase,inflorescence primordium differentiation phase,bract differentiation phase,ligulate flower primordium differentiation phase,tubular flower primordium differentiation phase,tubular flower corolla and stamen primordium differentiation phase,tubular flower pistil primordium differentiation phase.And the regression equations between flower bud differentiation phase and plant growth index were obtained.[Conclusion]Significant linear relationships exist between each growth index and its flower bud differentiation phase.And the most significant relationship is between days after seeding and flower bud differentiation phase.
