Flavanol content (mg/kg) in Monastrell grapes from grapevines under non-irrigated (rainfed) and regulated deficit irrigation (RDI) conditions.
| Treatments (T) | |||
|---|---|---|---|
| Flavanols | Rainfed | RDI | p-Value 1 |
| Catechin | 48.1 ± 3.3 | 38.6 ± 8.1 | 0.131 |
| Epicatechin | 58.1 ± 1.1 b | 37.6 ± 2.7 a | *** |
| Epicatechin-3-gallate | 68.8 ± 4.3 b | 50.4 ± 5.8 a | ** |
| Procyanidin B1 | 10.0 ± 1.4 | 8.8 ± 1.5 | 0.242 |
| Procyanidin B2 | 9.5 ± 1.3 | 10.8 ± 1.2 | 0.322 |
For each flavanol, different letters indicate significant differences between treatments (p ≤ 0.05). 1 Statistical significance: ** p ≤ 0.01, and *** p ≤ 0.001. When there is no difference between treatments (p > 0.05), no significance letters are shown. Experiments were performed in quadruplicate, and results for each parameter are presented as means ± standard deviation (n = 4).
