Feulgen cytophotometry was used to detect possible changes in the 2C DNA content in the various parts of the apical bud of Sinapis alba during floral evocation and flower development. This study showed that there was no significant difference in the 2C DNA content between the vegetative, evoked or reproductive meristems. In vegetative plants, the 2C DNA content was lower in the leaf primordia than in the meristem. This content in the leaf exhibited a further decrease during the floral transition. In the flower primordia, the 2C value never exceeded the typical value of the meristem. In the flower at anthesis, the DNA content was lower in the pistil and stamen than in the meristem.
