Abstract: To elucidate physiological basis of photooxidation and shading tolerance in rice, 18 rice varieties have been identified by simple and effective screening technique for photooxidation and shading tolerance. Results showed that a photosynthetic ecology type adaptated for wide range of light intensities could be selected out. PS Ⅱ activity and RuBPc activity in those varieties declined slower and photosynthetic rate, dry matter weight were relatively stable under adverse light stress.

Key words: photooxidation, photosynthesis, shading tolerance
