View larger version (22K): [in a new window]   Fig. 1. Effects of extended photoperiod on turf quality of creeping bentgrass under heat stress. Vertical bars on the top indicate LSDs (P = 0.05) for treatment comparison at a given day of treatment. Vertical bars on the right indicate LSDs (P = 0.05) for turf quality comparisons across time within a treatment.

Vertical bars on the top indicate LSDs (P = 0.05) for treatment comparison at a given day of treatment. Vertical bars on the right indicate LSDs (P = 0.05) for comparisons across time within a treatment.

Vertical bars on the top indicate LSDs (P = 0.05) for treatment comparison at a given day of treatment. Vertical bars on the right indicate LSDs (P = 0.05) for comparisons across time within a treatment.

Vertical bars on the top indicate LSDs (P = 0.05) for treatment comparison at a given day of treatment. Vertical bars on the right indicate LSDs (P = 0.05) for comparisons across time within a treatment.

Vertical bars on the top indicate LSDs (P = 0.05) for treatment comparison at a given day of treatment. Vertical bars on the right indicate LSDs (P = 0.05) for comparisons across time within a treatment.

View larger version (29K): [in a new window]   Fig. 6. Effects of extended photoperiod on total cytokinin content in leaves (A) and roots (B) of creeping bentgrass under heat stress. Vertical bars on the top in (A) indicate LSDs (P = 0.05) for treatment comparison at a given day of treatment. Vertical bars on the right in (A) indicate LSDs (P = 0.05) for comparisons across time within a treatment. Letters above the columns in uppercase in (B) indicate the differences among photoperiods at a given day of treatment (P < 0.05). Letters above the column in lowercase in (B) indicate the differences between 16 and 32 d within the same photoperiod treatment (P < 0.05).
