From: Transcriptomic study of pedicels from GA3-treated table grape genotypes with different susceptibility to berry drop reveals responses elicited in cell wall yield, primary growth and phenylpropanoids synthesis

GA3 not only increases berry and pedicel dimensions but also exacerbates postharvest berry drop. a Effects of GA3 application on bunches from cv. Thompson Seedless. The image illustrates the notorious increase on berry size produced by GA3 compared to a non-treated cluster of the same vine. b L23 exhibits high susceptibility to postharvest berry drop under GA3 treatment conditions. Total weight of berries separated from cap stems against total weight of bunches after shaking is reported. Mean and standard deviation are shown on each bar and error bar (replicates for Season 1, Season 2 and Season 3 were 15, 8, 8, respectively, on each point). Red abscissa line in the graph shows 3% berry drop, a recommended tolerance value for high quality table grape exportation. Data were analyzed with ANOVA and Tukey HSD tests to find significant differences between conditions (p < 0.05). c Pedicel dimensions increase in GA3-treated samples. Scatter plots of variables show differences in dimension of berry and pedicel. Total soluble solids and firmness were used as indicators of phenological development. V + n: Number of weeks (n) passed since veraison (V). The numbers ‘0’, ‘15’, ‘30’ represent the number of days spent in cold storage after harvest time (n = 30)
