The effects of environmental conditions on the flowering of Majorana syriaca L. (= Origanum syriacum var. syriacum) were studied. Under natural conditions, flowering starts at the beginning of May. Full bloom was observed in two flushes from early June until September. M. syriaca was found to be an absolute long-day plant, requiring at least 28 long days (LD) for flower initiation. More LD were, however, required for the completion of flower formation and hormal development of the inflorescences. The critical day length for flower induction was 12 h, but full flowering required a longer photoperiod. Photoperiodic flower induction is not transmitted from one branch to another. There is no cold requirement for flowering in M. syriaca. Increased growing temperatures reduced the time needed from the start of long-day treatment to anthesis, but high temperatures greatly decreased the number of flowers. Decreasing light intensity in the field by shading delayed flowering and reduced the proportion of inflorescence weight in relation to total plant weight. © 1989 Taylor & Francis Group, LLC.
