Comparison of thermostability of PSII between the chromatic and green leaf cultivars of Amaranthus tricolor L

Comparison of thermostability of PSII between the chromatic and green leaf cultivars of Amaranthus tricolor L

In the present study, we investigated the antioxidative potential in leaves of the chromatic (CC) versus green (GC) Amaranthus tricolor L. under moderate high-temperature stress at 45°C. Before heat stress, CC had significantly higher levels of betacyanins [about 3.2 mg g⁻¹(FM)] than the green [1.8...
