Abscission dynamics and time course of polar auxin transport in grapevine fruitlets (a) Estimation of fruitlet abscission at 7, 10, 14 and 17 DAF plotted with average fruitlet volume at the same DAF. Percentage of fruitlet abscission at 7, 10, 14 and 17 DAF equals the percentage of 1 minus the ratio of berry number per cluster at 7, 10, 14 and 17 DAF and berry number in the same cluster at 3, 6, 10 and 13 DAF, respectively (see Additional file 4: Table S2). b Percentage of polar auxin transport at 7, 10, 14 and 17 DAF after an 8-h transport period. For (a) and (b), asterisk indicates that fruitlet abscission or auxin transport is significantly different from the corresponding value at 7 DAF (p < 0.05). Error bars represent SE of three replicates. c Calculated slope of the 7, 10, 14 and 17 DAF regression lines presented in Fig. 1a
