Non-Stomatal Depression of Photosynthesis Caused by Water Stress on Scaevola Taccada Plants
|dc.description.abstract||Plants of Scaevola taccada were grown in hydroponic solutions at different water potentials obtained by addition of either polyethylene glycol 1500 or sea water. The photosynthetic rates of detached leaves produced under treatment were obtained at high (525 u moles/m2 sec) and low (47.5 u moles/m2 sec) radiant flux densities. Photorespiration was reduced by the use of N2 gas and CO2 concentration of 400 ppm. A significant depression of photosynthesis was caused by the water stressing solutions under both the high and low intensity conditions. The depression under low light conditions varied linearly with respect to the osmotic potential of the hydroponic solution in the range of -2.0 to 0 M pascals and irrespectively of whether PEG or sea water was used to stress the plant.|
