The effects of riboflavin feeding on leaf flavin content and plant flowering time under long days. Ten-day-old plants grown in long days were fed with riboflavin or treated with water in control. Two days later, leaf flavin content was determined (a). Subsequently, plant flowering time and rosette leaf number were scored (b). Data shown in bar graphs are mean values ± standard deviation bars of results from three independent experiments each containing three repeats and 15 plants per repeat. Different letters on top indicate significant differences by analysis of variance and least significant difference test.
