The Effect Of GibberellicAcid in Enhancing Salt Tolerance On Yield Components Of Wheat (TriticumaestivumL.)


Abstract in English

At Tishreen University in the Faculty of Agriculture a study was performed during the year(2014-2015),The experiment aimd to demonstrate the effect of increasing concentrations of both sodium chloride(0,10,15,20 dsm-1) and gibberellic acid(0,25,75,100 mg/l) and their interaction on some yield components of weat (SHAM10).The experiment was designed as Completely Randomized Design(CRD)by three replicates(3x4x4).Data were statistically analyzed to find out the least significal differences (LSD)between treatment at(0,05)level.Results indicated that increasing of sodium chloride concentration caused significant decreases in yield components(biological yield,spikelength,numberofspikelets/spike,number of grains/spike,weight of1000 grain and grains yield/pot.The treatment with GA3 acid especially (75)mg/l indicated significant increases in all averages of yield components.Results of interacions for both factors indicated that foliar aplication of GA3 acid counteracted that advers effects of high concentrations of sodium chlorde of yield components of the (SHAM10).
