Research Abstract

The bluing mechanisms and applicable horticultural plants were investigated about the cultivation technique which change red flower petals into blue by absorbing molybdenum (Mo). The anthocyanins and Mo formed blue complexes with a specific molar ratio under weakly acidic to neutral conditions in vitro. In cyclamen petals, the annual differences were caused in degree of bluing because percentages of the anthocyanin which could be combined with Mo varied by an environmental condition.
