Salinity and high temperature are important environmental adversaries affecting plant growth. Seed pretreatment with thiourea may be an important strategy to cope with these stresses. The objective of this work is to induce salinity and high temperature diminished the growth of both varieties of wheat but tolerant variety (S-24) was relatively less affected than sensitive (MH-97) in terms of growth parameters. Plants raised from pretreated seed of both varieties, but this improvement was greater in the sensitive variety. Main effects of thiourea are improved water status of plant and revealed...
