Fig. 6: Modifications in ethylene release rate in the berries with different treatments.

The berries at 60 DAB were used in the in vitro treatment, i.e., half of each berry cluster was immersed in the treatment solution, which was refreshed every 3 days. The berries at different DAT were used for the determinations of ethylene release rate. The solution of 100 µM 1-aminocyclopropane-1-carboxylate (ACC) and water (CK) were used as positive and negative controls, respectively. MT melatonin, Flu fluridone, FW fresh weight. Values represent the mean ± SD of three replicates, and each replication contained 50 berries, which were randomly sampled from the same vine. The differences are not significant at the 5% significance level among the values with the same small letter at the same DAT
