Salinity is one of the most severe abiotic stresses for crop production. The present study was conducted to evaluate the effect of NaCl on growth and some biochemical parameters in chickpea (Cicer arietinum L.) seedlings. Chickpeas were grown hydroponically for 14 days and then treated with 0 mM and 200 mM NaCl. Plants were harvested for the experiment 7 days after salt treatment. Salinity showed marked changes in growth parameters (fresh and dry weight of roots and shoots) and the amount of photosynthetic pigments. The study revealed that the activity of photosystems (PS I and PS II) under salt stress is lower than that of plants growing under normal conditions. The spectral characteristics of the chloroplasts isolated from chickpea leaves were studied by the fluorescence method at liquid nitrogen temperature (77K). Under salt stress, the chloroplast fluorescence emission spectrum decreased in the parts of the spectrum characterizing the PSII (maxima at 686 nm and 695 nm) and PSI complexes (maxima at 735 nm).
