Fig. 8.
Content variation and relative abundance of endogenous IAA-related compounds in grapevine fruitlets. IAA conjugates (a), IAA oxidation products (b) and IAA precursors (c) content at 7, 10, 14 and 17 DAF 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 three replicates. d Relative abundance of IAA-derived compounds at 14 DAF. Relative abundance equals the number of molecules per ng, estimated using molecular weight of each compound, divided by the total molecules. DW, dry weight
