Flower forcing can be achieved by adjusting the factors effecting flowering behaviour, viz. photoperiod, temperature and humidity.
Chemical flower forcing can be done through the application of fertilizers, used both for retarding and stimulating flowering; and plant hormones, including gibberellin, growth retardants like Cycocel and growth inhibitors. Mechanical flower forcing is achieved by operations such as, pruning, leaf trimming, ringing, budding or grafting, smoking, low-temperature storage and breaking dormancy.
