Off-Season Flower Induction of  Praying mantis ginger Larsenianthus careyanus (Benth.) W. J. Kress & Mood (Zingiberaceae) through Low Temperature and Night Break

The experiment was carried out to study the impact of chilling and night break on the flowering of ornamental plants in their off-season period. Larsenianthus careyanus (Benth.) W.J. Kress & Mood is a wild potential ornamental ginger naturally growing in the evergreen forest of North Eastern states of India was selected for the current study. The rhizomes were collected and stored at 15°C for 8 months during March to October. The sprouted rhizomes after chilling treatment were planted at regular interval and sprouted plants were transferred to greenhouse with controlled light during night hours
using incandescent lamp to extend flower production from December to March. Off-season flowering was observed during January to March. A detailed morphological analysis of 23 attributes of plants under study was
recorded.
