Mulberry (Morus alba L.) belongs to family Moraceae، is a multipurpose woody perennial، deciduous tree and is mainly cultivated for sericulture. Salt problem is considered as one of the most important environmental factors، limiting plant growth and productivity of arid and semiarid regions. During stress conditions plants need to maintain internal water potential below that of soil and maintain turgor and water uptake for growth. This requires an increase in osmotica، either by uptake of soil solutes or by synthesis of metabolic (compitable) solutes. One of the most common stress responses in plants is overproduction of different types of compitable organic solutes e.g. proline، protein، sugar etc. (Ahmad et al.، 2006; Ahmad et al.، 2008; Ahmad and Sharma، 2008). The accumulation of proline is thought to function as osmoprotectant and is a unique plant response to environmental stress. Soluble proteins and sugars have also been shown to accumulate under salt stress (Ahmad and Jhon، 2005). Several biochemical processes are affected by salinity، particularly nitrate assimilation and nitrate reductases activity (NRA) (Ahmad and John، 2005). The present study was performed to evaluate the effects of salt stress on growth، water relations and gas exchange of two mulberry cultivars.
