Photosynthetic Response of Elephant Grass (Pennisetum purpureum) to NaCl Salinity
Abdulkhaliq A. AL-Shoaibi

Photosynthetic responses of the C4 grass (Pennisetum purpureum) to three NaCl salinity concentrations (100, 200 and 400 mM) along with control (0 mM NaCl) were studied. The results showed that all the three salinity treatments did not affect the quantum efficiency of PSII photochemistry (Fv/Fm) compared to control. However, only the highest salinity concentration of 400 mM, significantly reduced (p<0.001) the light saturated assimilation rate (Asat), the quantum yield (φ), the CO2 saturated rate of CO2 uptake (Amax) and the carboxylation efficiency of P. purpureum, compared to control. Therefore, it is possible for P. purpureum to attain high rates of photosynthesis under low and medium salinity levels.
