Abstract
The approximately maximum photosynthetic rate was 10 2±0 5 μmol m 2 s 1 in leaves of Citrus grandis . Whereas the value was 6 4±0 8 μmol m 2 s 1 in leaves exposed to the supplementary UV B irradiation (3 4 4 2 μW cm 2 ,245～297 nm,45 d). It decreased by 37 2% as compared with control plants. The apparent quantum yield 〔μmol CO 2 uptake mol 1 (photons) 1 〕 was 0 075±0 012 in leaves of control plants, whereas 0 041±0 008 in leaves of UV B treated plant. It was lower than that of control plants significantly. The approximately maximum carboxylation rate in control plants was 57 1±1 5 μmol m 2 s 1 That was higher than that of the UV B treated plant by 30 9%. And the approximately maximum rate of electron transport declined by 30% in leaves of UV B treated plants as compared with the control plants. The UV B treated plants also had lower efficiency of light energy conversion and chlorophyll content. It may suggest that photosynthetic carboxylation rate and electron transport rate were suppressed by UV B irradiation. And muliprocession of photosynthesis was inhibited when UV B irradiation was supplied.
