Abstract: The high frequency regeneration system of carnation from leaf to callus to plantlets was established.
Then genetic transformation of the carnation with the ACO an tisense gene.which controled by flower-specific expression
promoter(PchsA)was performed via agrobacterium mediated method and obtained 3 of transgenic plants
via the pathway of regeneration plantlets from callus at last.Th e resuhs of the PCR and PCR.Southem hybridization
analysis showed that the carnation ACC oxidase antisense gene Was integrated into carnation genomes.It will be a
good foundation for improvement the longevity of carnation flowers.

Key words: Carnation, ACC oxidase, Antisense gene, Genetic transformation
