Within each experiment values that are annotated by different letters are significantly different from each other (Duncan P < 0.05, after a significant main effect of Light in the ANOVA analysis). Data are represented as mean ± SEM. DD, continuous darkness. DimDim, continuous dim white light. LL continuous light. n/a, not applicable.
