Hydrogen Sulfide Alleviates Postharvest Senescence of Grape by Modulating the Antioxidant Defenses

Figure 4

Effects of H₂S on the contents of ascorbic acid (a), flavonoid (b), total phenolics (c), reducing sugar (d), and soluble protein (e) in grape pulp. Grape clusters were fumigated with 1.0 mM H₂S donor NaHS aqueous solution with water as the control groups for 0–7 d. Data are presented as means ± SD (). FW = fresh weight.
