All values were means ± sd, n = 10 (fruit weight, transverse diameter, longitudinal diameter, firmness, color L*, a*, b*); n = 3 (titratable acidity, TA; total soluble solids content, TSS). Color L represents the brightness (0 means black, 100 means white); a represents the redness and greenness (a > 0 means the degree of red; a < 0 means the degree of green); b represents yellowness and blueness (b > 0 means the degree of yellow, b < 0 means the degree of blue). Values with different letters are significantly different in the same row (p < 0.05).
