. Total carotenoid concentration in ripe fruit skin and flesh of apple cultivars as measured by HPLC analysis. Fruits were harvested ripe from tree and separated into skin (peel) and flesh samples for carotenoid extraction and analysis. Error bars are standard errors of the mean from three technical replicates, with each tissue being the pooled sample of at least seven fruit, at P = 0.05 level. Bars with similar letters are not significantly different (P = 0.05), using one-way ANOVA analysis was followed by a multiple-comparisons T-test.
