Table 1.

T₅₀ values (min) for Mn²⁺ release and loss of F_V/F_M during 1200 min light exposures.

		460 nm	660 nm
Mn2+ release	*T fast	38.5 ± 10.3 (0.18)	25.6 ± 14.8 (0.18)
	*T slow	495 ± 117 (0.73)	459.07 ± 176 (0.77)
	$y_0$	0.91 ± 0.07	0.94 ± 0.12
FV/FM decay	*T 50	15.4 ± 1.2	15.4 ± 1.4
	$y_0$	0.17 ± 0.05	0.17 ± 0.05

Each T₅₀ is presented ± standard error. Mn²⁺ release was fitted to a biphasic curve and the T₅₀ for the slow and fast phase are presented individually ± standard error. The $y_0$ represents the offset used for the fitting ± standard error. Amplitudes are presented in parenthesis.
