Abstract:

The spathe color of 23 cultivars of Anthurium were divided into six groups：red，pink，green，white，yellow and mixed color group.The distribution of flower pigments in the Spathe tissue was observed and the flower pigments in Spathes were generally identified and quantified.The results indicated that flower pigments of Spathe mainly included flavonoids (including anthocyanins，flavones，and flavonols)，chlorophyll，and carotenoids.The flavonoids of most cultivars mainly distributed in the both upper and lower epidermal cells，also in palisade tissue of some cultivars’ Spathes such as ‘Xavia’.The chlorophyll and carotenoids were found in the palisade tissues.All cultivars tested contained flavonoids.The red Spathes contained more anthocyanins than other cultivars，besides，the green Spathes contained chlorophyll.Only in Spathe of ‘Tropical Night’，a little carotenoids were detected.The anthocyanins and chlorophyll were key factors for Spathe coloration.In general，total anthocyanins content (TAC) and chlorophyll content (TCh) showed negative correlation with color lightness (L*)，while the positive correlation with chroma (C*).In red and pink spahes，the increase of TAC could enhance the red hue；while in green and white Spathes，the accumulation of chlorophyll might strengthen the green and yellow hue.
