| 英文摘要 | a high yielding rice variety mutant (oryza sativa l., zhenhui 249) with low chlorophyll b (chl b) has been discovered in natural fields. it has a quality character controlled by a pair of recessive genes (nuclear gene). the partial loss of chl b in content affects the efficiency of light harvest in a light harvest complex (lhc), thus producing the difference of the exciting energy transfer and the efficiency of photochemistry conversion between the mutant and wild-type rice in photosynthetic unit. the efficiency of utilizing light energy is higher in the mutant than that in the wildtype rice relatively. for further discussion of the above-mentioned difference and learning about the mechanism of the increase in the photochemical efficiency of the mutant, the pico-second resolution fluorescence spectrum measurement with delay-frame-scanning single photon counting technique is adopted. thylakoid membranes of the mutant and the wild-type rice are excited by an ar+ laser with a pulse width of 120 ps, repetition rate of 4 mhz and wavelength of 514 nm. compared with the time and spectrum property of exciting fluorescence, conclusions of those ultrafast dynamic experiments are: 1) the speeds of the exciting energy transferred in photo-system i are faster than that in photo-system ii in both samples. 2) the speeds of the exciting energy transfer of mutant sample are faster than those of the wildtype. this might be one of the major reasons why the efficiency of photosynthesis is higher in mutant than that in the wild-type rice. |
