The effect of daylength and temperature on Chl fluorescence parameters
Fv/Fm, qO, and qN, measured under saturating light conditions (1,000 μmol photons m−2 s−1); n = 8 ± se. Two-way ANOVA analysis indicates statistically significant differences due to daylength, temperature, or an interactive effect of both factors. •, ▪, and *, Significant differences due to daylength, temperature, and their interactive effect, respectively. One symbol, P ≤ 0.05; two symbols, P ≤ 0.01; three symbols, P ≤ 0.001; n.s., not significant.
