Abstract: We choose Chlamydomonas reinhardtii as our subject to focus on it’s photosynthesis characteristics under salty stress. The growth rate of C. reinhardtii under 0.04 mol·L-1 NaCl treatment showed no obvious inhibition but it decreased about 50% under 0.075 mol·L-1 NaCl treatment. In the low light density, the photosynthetic rate and respiration rate of C. reinhardtii were stimulated by the NaCl stress within 7 hours after the treatment. While in the high light density, the photosynthetic rate and respiration rate decreased under NaCl treatments. The increase degree and decrease degree of the photosynthetic and respiration rates were parallel with the concentration of NaCl.

Key words: Chlamydomonas reinhardtii, salt stress, photosynthesis characteristics
