General Information
Term photoperiodism, flowering ID (Ontology) GO:0048573 (Gene Ontology)
Definition A change from the vegetative to the reproductive phase as a result of detection of, or exposure to, a period of light or dark of a given length. The length of the period of light or dark required to initiate the change is set relative to a particular duration known as the 'critical day length'. The critical day length varies between species.[ ISBN:0582015952 ISBN:0697037754 ISBN:0709408862 ]
Also Known As "photoperiodic control of flowering time" ; "photoperiodic control of inflorescence development" ; "response to day length, flowering" (for all, see Synonyms field below)
