Fig. 2 Effects of removal of UV-B components from natural sunlight on 3 min dark adapted quantum efficiency of PSII photochemistry (F(v)/F(m)) in Saussurea superba in August 2008. Data numbers were from 4 to 22 during the 16 days of continue measurement due to the influence of weather condition. Vertical bar is SE. **, p < 0.01.
