| Abstract: | The paper studied chlorophyll content and chlorophyll fluorescence characteristics(Fv/Fm,Fv/Fo and ΦPSII)of Cyclobalanopsis gracilis under the different UV-B radiative forcing.Three intensities of radiative forcing were treated in this experiment:radiative forcing (CK),+10% radiative forcing and-80% radiative forcing.To investigate UV-B radiation forcing effect on the growth of Cyclo-balanopsis gracilis.The results showed:under-80% radiative forcing treatment,chlorophyll content,fluorescence parameters Fv/Fm,Fv/Fo,and ΦPSII were higher than radiative forcing (CK) and +10% radiative forcing,The results indicated that Cyclobalanopsis gracilis had better adaptability under the lower radiative forcing,it can promote its growth;but it had poor adaptability under higher radiative forcing conditions. |
