Figure 2: Effects of H2S on browning index of grape rachis (a), weight loss percentage of grape berries (b), grape berry firmness (c), total soluble solids (TSS) (d), and titratable acidity (e) in grape flesh. Grape clusters were fumigated with 1.0 mM H2S donor NaHS aqueous solution with water as the control groups for 0–8 d. Data are presented as means ± SD (standard deviation) ( rachis for (a), grape clusters for (b), grape berries for (c), replicates for (d), and replicates for (e)). The symbols and in this figure and the following ones stand for a significant difference between water control and 1.0 mM NaHS treatment at and , respectively. FW = fresh weight.
