“…This increase in ratio in the packed flowers could be due to either an increase in the amount of cyanidin 3-rhamnosylglucoside or a decrease in pelargonidin 3-rhamnosylgluoside. These 2 anthocyanins are the principal anthocyanins in anthurium spathe (15). Leaf anthocyanins probably are more slowly turned over than floral pigment with a half life of 7 to 12 days (6 ) vs. the 25 to 31 hr for leaf tissue (29).…”

Physiological changes accompanying anthurium flower (Anthurium andraenum Andre) senescence were monitored. Silver pulse treatment of flower stems was used to modify the senescence process. Florets on the spadix continued to open for 5-10 days after harvest. In both treated and untreated flowers, respiration rate was low until senescence began 8 days after harvest. The rate of increase in respiration of silver treated flowers was half that of the controls. Ethylene production remained low throughout the postharvest life of the flowers. Ten days from harvest spathe color began to change from red to blue with no significant changes in the ratios of the anthocyanins. There was a simultaneous change in tissue pH, from 5.2 to 5.6. Tissue organic acids remained constant during senescence. There was a significant increase in spathe tissue ammonium ion due, apparently, to protein breakdown which probably caused the increase in tissue pH. The concentration of tissue phenolics increased during senescence and could have intensified the color change by copigmentation. Flower senescence apparently was not due to a shortage of carbohydrates, though tissue starch levels did decline by about 25%. The ratio of free sugars in the stem, spathe and spadix remained constant with a slight decline in concentration during postharvest life. Senescence probably was caused by water stress due to stem plugging of undetermined nature. Silver-pulsing of the stem reduced the amount of plugging and therefore reduced the rate of change of all the senescence processes.

“…Metabolomics analysis has the characteristics of broad spectrum, more accurate and more able to discover new metabolites. In previous reports, the main anthocyanins identified in anthurium were cyanidin 3-rutinoside and pelargonidin 3-rutinoside [28,29]. In A. amnicola, peonidin has also been synthesized [30].…”

Anthurium is the second largest tropical flower crop in the world. The international market has urgent demand for anthurium varieties with different spathe colors, which mainly arises from the types and contents of anthocyanin. The flavonoid 3-O-glycosyltransferase (UF3GT) gene is the key enzyme involved in promoting anthocyanin accumulation through glycosylation downstream of the anthocyanin synthesis pathway (ASP). Abnormal functioning of UFGT usually results in a reduction in or loss of anthocyanins. The aim of this study was to reveal the role of one anthurium UFGT gene (AnUFGT1) in ‘Xueyu’ (X), an anthocyanin-deficient mutant of ‘Alabama’. Metabolome analysis was used to analyze the metabolic products in the ASP to determine the possible key link of the anthocyanin deletion mutation. Agrobacterium-mediated transformation of Arabidopsis ufgt and ‘X’ validated the function of AnUFGT1. The results of comparative metabolome analysis of ‘X’ and ‘Alabama’ showed that there was no significant difference in product levels upstream of ASP. The expression levels of AnUFGT1 were significantly greater in ‘Alabama’ than in ‘X’. The overexpression of AnUFGT1 in Arabidopsis ufgt significantly increased its anthocyanin contents. The overexpression of AnUFGT1 in ‘X’, mediated by a new injection method, can only promote the synthesis of trace anthocyanins. These results showed that AnUFGT1 could fully compensate the phenotype of Arabidopsis thaliana ufgt, but only partially compensate the anthocyanidin-deficient phenotype of anthurium mutant X. This difference suggested that anthocyanin-deletion mutations in anthurium ‘X’ are associated with AnUFGT1, but AnUFGT1 is not the only factor. There should be other factors interacting with AnUFGT1 that cause anthocyanin deficiency.

“…Color may be influenced by such factors as the amount and kinds of anthocyanins, pH, metal chelation, copigmentation involving flavones and flavonols and the presence of background pigments, such as chlorophyll and carotenoids. Anthocyanins in some cultivars of Anthurium andraeanum were identified previously as 3 -rhamnosylglucosides of cyanidin and pelargonidin (3).…”

Spathe color is shown to be determined by relative concentrations of the anthocyanins cyanidin 3-rhamnosylglucoside and pelargonidin 3-rhamnosylglucoside in Anthurium andraeanum Linden ex Andre. A predominance of cyanidin 3-rhamnosylglucoside results in pink to dark red colors, whereas a predominance of pelargonidin 3-rhamnosylglucoside results in coral to orange. A flavone present in large and variable amounts was characterized but not demonstrated to have a modifying effect on cyanic shades.
