Fig. 1. Effects of the combined drought and heat stress on turf quality, Fv/Fm ratio, electrolyte leakage (EL), and chlorophyll content for ‘Midnight’ and ‘Brilliant’. Vertical bars on the top indicate LSD values (P = 0.05) for the comparison between cultivars at the given day of treatment. Vertical bars on the right are the LSD values for the comparisons over time of treatment for each cultivar.
