Fig. 6From: Regulation of polar auxin transport in grapevine fruitlets (Vitis vinifera L.) and the proposed role of auxin homeostasis during fruit abscissionEndogenous GAs and free IAA content in grapevine fruitlets. IAA content at 7, 10, 14 and 17 DAF (a) and GA1 and GA3 content at 7 and 14 DAF (b) determined by LC-MS/MS. Asterisk indicates that concentration is significantly different from the corresponding value at 7 DAF (p < 0.05). Error bars represent SE of two (a) or three (b) replicates.
