Carotenoid profile in ripe-red tomato pericarp tissue of two det1 mutant genotypes, hp-2dg and hp-2j, in comparison to their isogenic normal counterparts
Values represent average carotenoid concentrations (in μg g−1 fresh weight) ± se. Different superscript letters indicate statistically significant differences between means of each carotenoid within each genotype pair [P(F) < 0.005].
