Effect of nacl salinity on the physiological attributes in the leaves of Trianthema portulacastrum L.

Effect of NaCl salinity on the absorption spectrum of photosynthetic pigments, leaf juice acidity (in the form of Titratable Acid Number) and osmotic potential of cell sap of the leaves of Trianthema portulacastrum L. was studied. Absorption spectrum of photosynthetic pigments, and TAN of the leaves decreased with increasing NaCl salinity in both sand and soil cultures. However osmotic potential was increased by 24 to 51 % and 2 to 31 % over control due to NaCl salinity.
