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.
