Abstract

A pot experiment laid out in factorial arranged in completely randomized design with three replications was implemented to evaluate the effects of seed priming in ameliorating salinity stress in sesame (Sesamum indicam L.) during seedling development and the early vegetative growth. Factors included five priming treatments : control (non priming) , hydropriming, halopriming with NaCl, KCl , CaCl2 + 2H2O and five levels of salt stress : zero, 4, 8, 12, 16 dS/m. Results showed that the effects of seed priming and salt stress on emergence percentage , time taken to 50% emergence of seedling (E50) , root and shoot length , root to shoot length ratio , dry weight of root and shoot , dry weight of leaf , leaf number and area were significant (P
