Abstract

Abstract

T he marine green macroalga Ulva lactuca was selected to study the effects of solar UVR (280~400 nm) on its photochemical efficiency.Results showed that the photochemical efficiency decreased when the thalli were exposed to high solar radiation in the late morning and recovered when it decreased in the late afternoon.The photochemical efficiency showed a typical pattern that it was the lowest during noon period with the higher values in the early morning and later afternoon.This noontime inhibition was caused not only by the photosynthetic active radiation (PAR, 400~700 nm) but also UV radiation.UV-Bsignificantly affected the photochemical efficiency.Long-term experiments showed that the photochemical efficiency was mostinhibited on the second day, how ever, it became less and less suppressed by UVR while the thalli became acclimated.
