For tocopherols, data are the means (±se) of five replicates using 20 seeds from a pool of 20 plants. For carotenoids, data are the means (±se) of three replicates of 100 seeds from a pool of 20 plants. Values for antheraxanthin and zeaxanthins are expressed in β-carotene equivalents. When significantly different (assessed by ANOVA; Supplemental Data Set 3), values were ranked into groups as indicated by the respective letter using a Newmans-Keuls test. ND, not determined; PC-8, plastochromanol-8; DW, dry weight.
