abstract：:The inductive effect of short-day (SD) cycles on floral-bud initiation in Impatiens balsamina was enhanced and the minimum requirement for SD cycles for flowering reduced by intercalated long days (LDs). Thus, floral buds developed into flowers with only 4 SD cycles in plants receiving them individually or in pairs al...
