Data are expressed as mean ± SD (n = 6). Values within a column for the same genotype with different lowercase letters between standard and undersized samples are significantly different (p < 0.05); values within a column with different uppercase letters between different standard genotypes are significantly different (p < 0.05). ChA: chlorogenic acid. OF: orange-fleshed. YF: yellow-fleshed.
