With the materials of super-hybrid rice Liangyoupeijiu and female parent Peiai 64 S and male parent medial duration Indica rice 9311,the adaptation to chilling temperature and high light between Liangyoupeijiu and its parents were studied through chlorophyll fluorescence parameters and key indexes of actives oxygen.

In this study,the effects of full sunlight after low night temperature on photosynthetic electron transport and absorbed light allocation in leaves of and Pittosporum tobira were examined by using chlorophyll fluorescence measurements.

The effects of the different light intensity on the chlorophyll fluorescence parameters in microcystic aeruginosa were studied by using unmodulated chlorophyll fluorometer.

Effects of nocturnal low temperature on photosynthesis of seedlings of two coffee species.;

Effect of nocturnal low temperature on the active oxygen metabolism in the leaves of two tropical seedings;

With nocturnal low temperature treatments for 12 h each day,the chloroplast ultrastructures were observed and net photosynthetic rate(Pn),stomata conductance(Gs),intercellular CO2 concentration(Ci),stomata limitation(Ls),transpiration rate(Tr) and water use efficiency(WUE) of Eucalyptus urophylla and E.
