Effect of seawater salinity (10% and 25%) on growth vigor of root and shoot, water relations and protein as well as nucleic acids in flag leaves of two wheat cultivars (Salt sensitive var., Gemmieza-9 and salt resistant var., Sids-1) during grain-filling was investigated. In general, seawater at 10% and 25% caused noticeable reduction in almost all growth criteria of root, shoot and flag leaf which was consistent with the progressive alteration in water relations (RWC & SWD), protein and nucleic acids (DNA and RNA) content of both varieties during grain filling. Furthermore, degree of leaf succulence and degree of leaf sclerophylly were severely affected by seawater stress in both wheat cultivars. The magnitude of reduction was more obvious at higher salinity levels than the lower one particularly in Gemmieza-9.
