Abstract
Experiments were carried out to study flowering response under four distinct controlled photoperiods (8, 11, 14 & 17 h d(-1)). A curvilinear facultative response was observed in almost all cultivars studied. Moss Rose, Pansy, Snapdragon, Petunia and Annual Verbena took minimum time to flower, when grown under 17 h. photoperiod however, it was significantly (P<0.05) increased, when photoperiod decreased to 8 h. These findings revealed a prospect of plant scheduling of the flowering time of facultative LDPs grown under short day photoperiod to extend their marketing period.
