Salt stress-induced proline accumulation, changes in ionic adjustment (na+/k+) and catalase in the tomato (solanum lycopersicum) leaf
Soil salinity is a major limitation to plant in many areas of the world. Present study has explored the effect of salinity on Proline content, mineral composition and antioxidant enzyme of tomato. Tomato plants were exposed to 0, 60, 90,120,150 mM NaCl.The Proline accumulation was studied by reading the absorption of chromophore at 520nm using spectrophotometer. The content of proline increase in tomato as the level of NaCl increase. Using atomic absorption spectrophotometer ion uptake for Na+, K+, Ca+ and Mg2+ were determined.
