Summary

A mixture of 1-naphthylacetic acid and 6-benzylaminopurine was found to be an effective substitute for the rhizome apex of attached rhizomes, when the plants were not at anthesis. The same mixture was not effective, however, when the plants were at anthesis. The same growth-regulators applied to the apical end of detached multi-node rhizome fragments did not maintain correlative inhibition unless growth-regulators were simultaneously applied to the basal end. Various interactions between apical and basal applications are discussed with regard to their role as a parental factor in apical dominance.
