Abstract

In order to compare the physiological responses of linseed (Linum usitatissimum L.) in DROUGHT and SALINITY stress conditions and salicylic acid foliar application, a greenhouse experiment was conducted based on completly randomized design with three replications in Yasouj university in 2015. Treatments including different levels of SALINITY and DROUGHT with similar osmotic potentials (-2, -4, -7 and -9 bar) in 8 levels and a control treatment were applied in Hoagland solution. Second factor was salicylic acid foliar application in 2 levels (0 and 0.5 mM). SALINITY and DROUGHT applied using sodium chloride and polyethylene glycol 6000, respectively. The results showed that leaf protein content, CATALASE activity, total chlorophyll and carotenoid significantly decreased compared to control by increasing SALINITY and DROUGHT levels, however salicylic acid could prevent this trend. PROLINE SOLUBLE SUGARS and malodealdehide content significantly increased compared to control by increasing SALINITY and DROUGHT. However salicylic acid could not prevent this trend. Shoot and root dry weights significantly decreased in SALINITY and DROUGHT stress treatments, compared to control and salicylic acid could prevent this decrease. Generally regarded to the most of the measured traits, impact of DROUGHT was more than SALINITY and salicylic acid could compensate the stress impacts on linseed.
