The effect of salinity on the growth, soluble sugar and mineral ions content of barley plant (hordeum vulgare L.)‎ and soil properties

الملخص EN

An experiment in plastic pots was carried out to know the effect of different salt concentration levels (50, 100 , 150 and 200) mMo1 / L of NaC1 in addition to distill water as a control treatment on the growth, soluble sugar and mineral ions content of barley plant (cv local) and the arable soi1 ; properties.

The results of the study shows an increase on salinity causing a decrease on the growth of plant in terms of stems length and their dry matter weight, also a decrease observed on the; concentrations of reduced sugar (19.75, 18,625, 15.19and 15.875) mg / gm as compared with the concentration (15.185) mg / gm at a control treatment ; while the concentrations of total sugar ( 22.30, 23.35, 24.085 and 25.99) mg / gm and sucrose (1.25 , 2.315 .

4.335 and 4.925) mg / gm were* increased, as compared with their concentrations (16.525 and 0.65) mg / gm respectively, at a control treatment.

The results showed that, the increase of salinity causes an increase on the concentration ofmineral! Ions (Na, Ca, Mg and Cl) on the shoot part of plant whereas (K ion was decreased; also the values of pH, EC and the concentrations of mineral ions (Na, Ca, Mg, K and CI) were increased on the arable soil.
