Effects of Climate Temperature and Water Stress on Plant Growth and Accumulation of Antioxidant Compounds in Sweet Basil (Ocimum basilicum L.) Leafy Vegetable

Figure 4

Effect of different climate temperatures (C, 25°C; T₁, 35°C; T₂, 45°C; and T₃, 55°C) and water stress (WS) treatments on total chlorophyll (a, b) and total carotenoids (c, d) after two sampling periods (S1, 14 days and S2, 21 days) in basil plants (mean ± SD, n = 10). Asterisks indicate significant differences between sampling periods of each treatment and differences between treatments for the same sampling period according to the Tukey test (α = 0.05).
