SUMMARY
Crops differ in their ability to grow under saline conditions; their responses are quite different and not fully understood. To study the response of tomato (Solanum lycopersicon cv.) to salinity, three tomatos (A5, T8 and T4) ( Lycopersicon esculentum.) genotypes were subjected to salt treatment and their responses were monitored in a set of experiments . The objective was to advance them as potential salt tolerant tomato scions and/or rootstocks. The strong correlations between the foliar content of sodium (Na+) and Chloride (Chl), the photochemical quenching (qP), the non photochemical quenching (NPQ), the linear electron transport rate (ETR), and plant growth suggest that these parameters can be used to screen genotypes for salt tolerance.
