The effect of salinity stress on germination characteristics and changes of biochemically of sesame seeds

Abstract

Objective of this study was to evaluate the effect of salinity stress on germination characteristics and biochemical changes of sesame seeds. Salinity stress at osmotic potentials of 0 (as control), - 3, -6, - 9 and -12 bar were adjusted using NaCl before the start of the experiment. Our results showed that, the effect of salinity stress for all traits was significant. By increases of salinity stress, germination percentage, germination, normal seedling percentage, seedling length and dry weight were reduced the ascorbate peroxidase and catalase activity, also proline content were at minimum at control and increased with increase in salinity stress, expressed by the osmotic potential.
