Fig 5. Diel variations of rETR.

Fig 5

Diel variations of relative ETR of low light (LL, closed circles) and high light (HL, open circles) cultures acclimated to different LD regimes, (A) 12L:12D, (B) 8L:16D and (C) 16L:8D. The values of rETR was determined from the instant ΦPSII multiplied by growth light irradiances. Shaded areas represent dark periods. Values represent mean ± SD of triplicate cultures under each regime.
