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.
