Wheat Varietal Behavior in Hydroponic and Soil Culture Under Saline Conditions
The experiment was conducted to compare two systems (hydroponic and soil culture). Seven wheat varieties differing in salt tolerance were grown under saline conditions (100 mol m3 NaCl) in these two systems. Ion contents (Na+, K+, CI‾, Ca2+ and Mg2+ ) in the fourth leaf were not correlated with ion contents in the flag leaf. There were few significant correlation coefficients between ion contents and grain weight per plant. Which suggests that ion contents in leaf sap may not be good indicators of salt tolerance in wheat. Linear correlation coefficients for grain yield, most of yield components and ion contents of seven wheat varieties between hydroponic and soil culture were non-significant. These results suggest that hydroponic culture system is independent from soil culture system.
