Popis: Changes in betacyanine (red pigment) concentration, betaxanthine (yellow pigment) concentration, and percent dissolved solids associated with growing time and season were studied in roots of 12 cultivars of table beet (Beta vulgaris L.) Differences among cultivars and cultivar × harvest date interactions were detected for each trait. Depending on cultivar and planting date, betacyanine concentration increased, decreased, or remained constant with increased growing time, while betaxanthine concentration and percent dissolved solids invariably increased over the same period. Beets planted on July 12, 1978, had greater pigment concentrations than beets planted on June 9, 1978, when grown the same number of days. At 83 days after planting, root weight was negatively correlated with betacyanine concentration (r = −0.44) and betaxanthine concentration (r = −0.40), but after 136 days, both correlations were reduced in magnitude (r = −0.23).
