Fig. 3: Pigment composition and concentrations in mutant and wild-type (WT) plants.

a Concentrations of carotenoids and chlorophyll in the leaves of the mutants and WT plants at 6 weeks after transplanting. b Concentrations of carotenoids and chlorophyll in the bolting stems of the mutants and WT plants at 6 weeks after transplanting. WT wild-type plant, M1 biallelic mutant, M3, M6, M16 homozygous mutants. The data are expressed as the means ± SDs. The same letter in the same histogram indicates that there is no significant difference between the values tested, according to the LSD (p < 0.05)
