| Harvest Month | TP (GAE mg/g DW) | FRAP (mmol TE /100 g DW) | HSA (%) | SSA (%) |
|---|---|---|---|---|
| Apr. | 28.7 ± 6.3 a | 11.2 ± 1.3 a | 56.4 ± 9.8 | 34.2 ± 4.8 a |
| May | 49.0 ± 9.0 b | 15.8 ± 1.1 b | 70.4 ± 10.8 | 53.8 ± 16.2 b |
| Jun. | 42.3 ± 8.4 b | 12.5 ± 0.9 a | 64.9 ± 7.7 | 54.1 ± 11.5 b |
| Jul. | 38.2 ± 5.1 a,b | 11.9 ± 2.4 a | 62.4 ± 11.1 | 48.7 ± 8.6 a,b |
| Aug. | 37.2 ± 3.5 a,b | 13.1 ± 1.1 a,b | 61.2 ± 8.7 | 49.7 ± 7.1 a,b |
| Sep. | 38.9 ± 5.2 a,b | 12.4 ± 2.4 a | 64.3 ± 13.9 | 45.3 ± 8.0 a,b |
| Oct. | 43.7 ± 7.5 b | 13.1 ± 1.7 a,b | 67.0 ± 7.0 | 42.8 ± 9.2 a,b |
The experimental results were analyzed by one-way ANOVA and Tukey-Kramer HSD. Values (mean ± SD, n = 6) with no letters in common are significantly different (p < 0.05) within a column.
