Improving salt tolerance in barley using salicylic acid as seed pre-treatment
2007
Razzaq, S.
Plants salt tolerance is a complex phenomena which includes the accumulation of ions in different plant parts. It is, therefore, important that strategies must be adaptabed so that some economic returns may be obtained by growing crop plants in low to moderately salt stressed areas. In this respect the use of salicylic acid may be of greater importance to enable the plants to tolerate, salinity. The data reported here suggested that SA applied in micro-quantities as pre-sowing seed treatment was beneficial in improving salinity tolerance in barley. The enhancement in salt tolerance was noted in terms of greater growth and photosynthetic capacity of leaves followed by increased K+ content and reduced Na+ of both shoot and root. Another important facet was the alleviation of oxidative damage as noted in terms of reduced production of H2O2 (a ROS) and MDA content and RMP. These findings suggested that application of SA was feasible for improving salinity tolerance in barley. Ho
