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

Figure 3

Effects of H₂S on the contents of total chlorophyll (a) and chlorophyll a (b) and chlorophyll b (c) in rachis and total chlorophyll (d) and chlorophyll a (e) and chlorophyll b (f) in grape pulp and on the content of carotenoid in rachis (g) and grape pulp (h). 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 ( for (a), (b), (c), and (g), for (d), (e), (f), and (h)). FW = fresh weight.
