In the present paper, effect of salt stress on growth and physiology of Atriplex lentiformis was investigated. Plants were first germinated and transplanted to pots. Salt stress was given as Hoagland’s solution spiked with50, 100, 200 and 300 mM NaCl. Leaf samples were harvested at 30, 60, and 90 days for determination of various parameters. Proline and sugars accumulation was also measured to determine the extent of tolerance of test plant to salinity. Low levels of salinity did not cause substantial inhibition of growth but higher concentrations induced a decline in root-shoot length and biomass. Chlorophyll content declined with increasing NaCl concentration, while proline and sugar content increased as compared to control. The results of present study indicate no significant effect of salinity on A. lentiformis. Improved to lerance to salt stress in A. lentiformis may be accomplished by decline in growth and photosynthetic activity and increased proline and sugar content. Based on these findings, the Atriplex can be suitable for revegetating moderately NaCl-contaminated soils.
