Comparative study on photoinhibition between two wheat genotypes

Changes in the efficiency of the primary light energy conversion, fluorescence quenching parameters and contents of photosynthetic pigments were compared between two wheat (Triticum aestivum L.) genotypes in response to high light stress. The contents of chlorophyll and carotenoid in Jing-41l were slightly higher than those in Xiaoyan-54. Under high Light stress, photoinhibition as indicated by a sustained decrease in PS II photochemical...
