indicating change in flesh color from pale yellow to more intense yellow as fruit ripened. NO treatment, however, strongly suppressed flesh yellowing (Fig. 5B and C). Consistent with suppressed color change of NO-treated fruit during storage, changes in other ripening parameters including softening (Fig. 6A), SSC accumulation (Fig. 6B) and decline in TA (Fig. 6C) also reflected NO-mediated delay in mango ripening
