Flowergenic callus was induced from the ovary surface of Allium fistulosum L. cultured on MS medium containing 0.5mg/L NAA and 0.5mg/L BA or 0.5mg/L kinetin. After 3-4 weeks of culture, the flower buds were developed from flowergenic callus. The continuous production of flowergenic callus was proliferated, when subcultured on the medium containing 0.5mg/L NAA and 0.5mg/L kinetin. However, frequency of flower bud formation from flowergenic callus was decreased as the subculture was repeated. Histological observation reveals that the developmental pattern of flower bud from flowergenic callus was closely similar to that of natural flowers.
