Abstract:

In India, it is popular among the farmers as Guldaudhi is a commercial flower which is grown for cut flowers, loose flowers, pot mum as well as bedding plant. Flowering in Chrysanthemum morifolium Ramat. is photperiodically controlled and it is a qualitative short day plant. Under sub-tropical climatic conditions of North India, chrysanthemum produces flowers from October to December. Limited duration of flower production in chrysanthemum is a major bottleneck for the commercialization of this crop in this region. Thus the artificial short days play an important role in altering the flowering of chrysanthemum plants through the manipulations in the daily day length or photoperiod has been successfully used for production of chrysanthemum flowers throughout the year in many countries. Study was conducted to investigate the effect of artificial short day conditions during summer months on growth and flowering of spray type chrysanthemum genotypes. It was found that genotypes Banlgori Local and Yellow Delight are highly suitable for early induction flowering as these are having comparatively high tolerance towards heat delay for year round cultivation programmes using black outs to impose short day conditions.
