| Abstract: | In order to reveal the effects of low temperature and light on tea photoinhibition,changes of chlorophyll fluorescence kinetics parameters in tea seedings were studied under conditions at temperature(0,5,10,15,25℃,25℃ as the CK) and light(3,4,6,10,15.5 klx)using illumination incubator.The results show that the chlorophyll fluorescence kinetics parameters of tea leaves maintained stable level at 25 ℃ under the light from 3 klx to 15.5 klx,but Fm,Fv/Fo,qP,ΦPSII,Fv′/Fm′ decreased and Fo,qN increased when the temperature decreased from 15℃ to 0℃.Change in chlorophyll fluorescence kinetics parameters was great under lower temperature and stronger light.It indicates that photoinhibition happened in tea leaves at lower temperature. |
