Modification of flower color for horticultural crops using metal ions

研究了红花瓣吸钼转蓝栽培技术的转蓝机理及适用的园艺植物。在体外弱酸性至中性条件下，花色苷与钼形成特定摩尔比的蓝色络合物。在仙客来花瓣中，由于不同环境条件下能与钼结合的花色素苷的百分比不同，导致了花瓣变蓝程度的年度差异。

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.
