Fig. 2: Accumulations of melatonin and its precursor (5-hydroxyserotonin) and metabolite (2-hydroxymelatonin) and the other signaling molecules during berry ripening.

From: Melatonin promotes ripening of grape berry via increasing the levels of ABA, H2O2, and particularly ethylene

The data in (a) and (b) were determined in 2016, and those in (c) and (d) were from 2017. In (d), ethylene release rate was detected from 14 DAB, and ABA and H2O2 were detected from 46 DAB. DW dry weight, FW fresh weight. Values represent the mean ± SD of three replicates, and each replication contained 240 berries, which were randomly sampled from the middle of the clusters of 10 vines. The differences are not significant at the 5% significance level among the values with the same small letter in (c) and (d)
