Effect of Sodium chloride concentrations on the Growth and Some Organic Chemical Compounds of Barley Hordeum vulgaris L.

An experiment in plastic pots was conducted to know the effect of different salt concentration levels ( 3 , 6 , 9 and 12 ) ds/m of sodium chloride in addition to distill water as a control treatment on the growth and some organic chemical compounds of barley plant ( local variety ) cultivated in Iraq . The results of the study shows an increase on the salt concentration levels causing a gradual decrease on the growth of plant in terms of stems heights (11.5-4.3 cm), water content percentages (87.6-85.0 %) and dry matter weights at the all salinity treatments as compared with distilled water at a control treatment , and increasing in the carbohydrates (1.5- 2.5 μg/gm), proteins (12.3-15 μg/gm) and proline (7.8-12.4 μg/gm) concentrations whereas the different patterns of a significant differences were observed between the all salinity treatments .
