The effects of 30 °C, 35 °C and 40 °C temperature regimes under well-watered (WW) (A,B) and water-stressed (DI) (C,D) conditions on the accumulation of total flavonoid content (TFC) of A. caudatus, A. hypochondriacus, A. cruentus and A. spinosus. Each vertical bar represents the mean value, and vertical line is a mean standard error (±) at 95% confidence level. Values among each species with the same letter(s) are not significantly different at p ≤ 0.05.
