Thus, floral transition occurred gradually and acropetally along the floral axis.

Within the floral meristem, the appearance of reproductive perianthic pieces also occurred acropetally.

These modulations could be propagated acropetally at a rate excluding direct action of auxin molecules at the sites of measurement.
