摘　　要：[Objectives] This study was conducted to explore the physiological mechanism of flower color variation in the white mutants of Anthurium andeaeanum. [Methods] The seven white mutants of 'Alabama' and 'Turenza' were used as materials to analyze the pigment types, flavonoid types and content and anthocyanin content in the wild type and mutants. [Results] The white spathe mainly contained flavonoids, flavonols, dihydroflavonols and dihydroflavonols; the white mutants of 'Alabama' had a higher total flavonoid content than the wild type, while the white mutants of 'Turenza' showed an opposite trend; and the spathe of the wild type had the highest anthocyanin content, and the pink part of the two-color mutant or the spathe of the binary color mutant contained trace anthocyanins, while no anthocyanins were detected in the white part of the mutants. [Conclusions] The main cause of the white mutants of A. andeaeanum is related to anthocyanin metabolism.[Objectives] This study was conducted to explore the physiological mechanism of flower color variation in the white mutants of Anthurium andeaeanum.
