A pot experiment was conducted in wird canopy of agriculture division-Kerbala university to asses the role of Trehalose adding on wheat cultivar (Fatih class) was planted during the winter season 2015 - 2016. Factorial experiment was designed using a completely randomized design (CRD) two factors and three replicates. first factor included four types of water different in the level of salinity which is (2, 4, 6 and 8 ds m-1) and the second factor include four Trehalose concentrations (T) (0,5,10 and 15 mg L-1) giving 48 experimental units. Plant height , flag leaf area, concentration of proline the activity of SOD and CAT has been studied in the flowering phase 100% and trehalose content in the straw wheat plant . The result showed that type of irrigation water affect on all traits studied , given salt level(8 ds m-1) the highest in some of the qualities of which the concentration of proline and concentration activety of enzyme SOD and enzyme CAT and content trehalose in the straw while gave salt level (8 ds m-1) lower rates studied Characteristics of which plant height , flag leaf area.
The levels trehalose added had significant effect on all traits, where the level of 15 mg L-1 ,gave The highest rate in most of qualities has been studied include the plant height and flag leaf area and SOD and CAT activity , content trehalose in the straw, While gave level 15 mg L-1 lower rate in concentration of proline. The study results showed significant effect of interactions between water types and trehalose added in all traits , as it found the best treatment of interference when spraying trehalose sugar in concentration of 15mg. L-1with irrigation water level of (8 ds m-1 ).
