Photosynthesis in rice under a salt stress

B.S. Tiwari, A. Bose, B. Ghosh

In four cultivars of Oryza sativa L., a gradual decrease in the activity of photosystems 1 and 2 as well as in chlorophyll (Chl) fluorescence transients and emission at 688 nm was observed with an increase in NaCl concentration. This decrease was more pronounced in salt-sensitive cultivars as compared to the tolerant ones. A drastic decrease in net photosynthetic rate was found in both cultivar types.

Additional key words: chlorophyll fluorescence; CO2 assimilation; electron transport rate; Oryza sativa L.; photosystems 1 and 2
