This culture system also promoted Dendrobium Chao Praya Smile
flowering and producing visible seeds within about 11 months. Unlike most tropical orchids, low temperature is
an important factor for the reproductive transition in temperate
Dendrobium orchids. When grown with only a
single plant regulator, well-developed floral buds were not
induced in Dendrobium and the flower bud either wither quickly
or develop into abnormal flowers.
