Comparison of the phenotypes and dynamics of sugar accumulation between Della and Rio. Three phenotypes, including plant height (a), number of above-ground internode (b), and days to flowering (c), were compared between Della and Rio. The statistical differences determined by Welch two-sample t test and presented using asterisks (*, **, *** indicate p < 0.05, p < 0.01 and p < 0.005, respectively). d Dynamics of total sugar concentration (measured by Brix) from 0 DAF (anthesis) to 38 DAF between Della and Rio. e Dynamics of internode water content from 10 DAF to 38 DAF between Della and Rio. The statistical differences in Brix (d) and internode water content (e) between internodes for each genotype and time point were calculated using one-way ANOVA and multiple comparison, and displayed by letter. The values within a genotype and time point labeled by the same letter are not significantly different at p = 0.05. For a–c, n = 36; for d, e, n = 6
