FIGURE 5.
Means and standard deviations of commonly used chlorophyll fluorescence parameters of wild-type (WT) and reduced hyperosmolality-induced [Ca2+]i increase 1 (osca1) plants under two treatments over time. The chlorophyll fluorescence parameters include maximum quantum yield of PSII photochemistry for the dark-adapted (Fv/Fm), non-photochemical quenching during light adaptation (NPQ_L2), fluorescence decrease ratio during light adaptation (Rfd_L3), and steady-state PSII quantum yield (ΦPSII_Lss). Statistically significant differences are indicated (∗P < 0.05; ∗∗P < 0.01; ∗∗∗P < 0.001).
