Basipetalauxin transport in grapevine fruitlets. a Percentage of auxin transport at 7, 10, 14, 17 days after flowering (DAF) after a 2-, 4-, 6- and 8-h transport period. Polar auxins transport was measured in excised fruits were percentage of auxin transport equals the percentage of radioactivity in receiver agars divided by the total radioactivity in the berries plus the receiver agars after a 8-h transport period. Linear regression is shown (blue line). m, slope; r2, coefficient of determination. b Percentage of auxin transport at 7 and 17 DAF after a 4-h transport period. Asterisk indicates that transport in acropetal and NPA controls is significantly different from basipetal transport (p < 0.05). Drawing represents fruitlet apical and basal zones, and IAA net flux direction. Error bars represent SE of three replicates
