Paper Abstract

Changes of chlorophyll fluorescence emission spectra of different position leaves were investigated during the later growth stages of rice leaves. Results showed that natural illumination induced a shift change of fluorescence emission intensity (both in P685 and P735) during the progressive senescence of rice leaves. These data suggested that changes of chlorophyll fluorescence emission spectra of different position leaves were possible due to the declined of energy and electron transport activities of PSII reaction center. On the other hand, different position leaves of rice were treated with 3-(3,4 dichlorophenyl)-1,1-dimethyl-urea (DCMU), the results showed that DCMU had a significant effect on Chl fluorescence emission spectra (both in P685 and P735) under room temperature and different position leaves had a different sensibility of DCMU. It is concluded that natural illumination plays an important role in the progressive senescence process of rice leaves.
