UV-B radiation (0.8 +/- 0.1 mW cm(-2)) and UV-B radiation supplemented with low intensity PAR (approximately 80 micro mol m(-2) s(-1)) affected photosynthesis at the level of antenna system as well as PS II reaction centre (Fo and Fm declined) in Phormidium corium (Agardh) Gomont. UV-B radiation resulted in decline in sugar content, peroxidation of membrane lipids as well as quantitative and qualitative changes in phosphoglycolipids and neutral lipids. Fatty acid profile did not show any qualitative changes due to the treatment, however, UV-B supplemented with low PAR resulted in slightly higher level of unsaturation. P. corium synthesized MAAs in response to UV-B. Quantity of MAAs increased when UV-B treatment was supplemented with low level PAR.
UV-B辐射（0.8±0.1毫瓦/平方厘米）以及补充了低强度光合有效辐射（约80微摩尔/平方米·秒）的UV-B辐射，在天线系统以及皮状席藻（Agardh）Gomont的PS II反应中心水平上影响光合作用（初始荧光Fo和最大荧光Fm下降）。UV-B辐射导致糖分含量下降、膜脂过氧化以及磷酸糖脂和中性脂的定量和定性变化。脂肪酸谱未因处理而显示出任何定性变化，然而，补充了低水平光合有效辐射的UV-B导致不饱和度略有升高。皮状席藻响应UV-B合成了MAAs。当UV-B处理补充低水平光合有效辐射时，MAAs的量增加。
