Effect of different treatments of salicylic acid on some morphological traits and yield of white bean in salinity condition

It has been proposed that salicylic acid (sa) acts as an endogenous signal molecule responsible for inducing abiotic stress tolerance like salinity stress in plants. the effect of different salicylic acid (sa) concentrations (0,0.1,0.5 and 1.0 mm) and 3 application methods (soil,foliar and priming) on stem diameter,dry weight,yield per plant,stem height,number of pods,number of seeds per pod and 100 seed weight of nacl (4 ds/m) stressed white bean (phaseolus vulgaris l.) was investigated. the results showed that the effect of applied concentrations and methods on the characteristics of stem height,stem diameter,pod number,seed per pod,yield per plant,plant dry weight,hundred seed weight weresignificant. the interaction of concentrations and methods used was significant on plant dry weight,stem height and 100seed weight. according to the results,the greatest impact was belonged to the soil treatment which was not significantly different from priming. among applied concentrations,the concentration of 0.1 and 0.5 mm were the most effective and the concentration of 1 mm was not significantly different from control.
