Abstract

Salinity is one of the most important limiting factors in growth and production of plants. Puccinellia distans is a perennial, salt tolerant forage. The object of this study was evaluation of the SALINITY effects of NaCl on growth, osmolite contents and CELL WALL COMPONENTs of Puccinellia distans. The plants were grown in greenhouse in hydroponic culture with Hoagland nutrient solution. Salt treatments included two levels of 0 and 200 mM sodium chloride. Plants were harvested before achieving to the reproductive stage. The results showed that SALINITY reduced growth parameters such as fresh and dry weight of shoots, dry weight of roots, relative water content and leaf number. SALINITY induced significant increase in concentration of Na+ and drastic decrease in potassium concentration in shoots and roots. Also electrolyte leakage increased due to SALINITY in shoots. SALINITY imposed significant increase in soluble sugars and phenols in the roots, but did not impose significant effect in shoots. Also, the total amount of amino acids, proline and cellulose increased due to SALINITY in both roots and shoots as well. Besides, lignin and soluble proteins increased in shoots under SALINITY. These results indicated that probably water deficit led to accumulation of osmolites for osmotic adjustment; however, it was not sufficient for maintaining relative water content. Consequently, water deficit accompanied with ions toxicity resulted in retardation of plant growth.
