Tobacco (Nicotiana tabacum L. cv KF109) seeds were artificially aged in a controlled environment of 45$^{circ}C$ and 80% relative humidity condition for different duration up to 14 days before priming in polyethylene glycol 6000 solution of equivalent osmotic potential of -0.8 MPa for 8 days at $25^{circ}C$. The seeds aged only and primed after aging were germinated at 15$^{circ}C$ and $25^{circ}C$ to observe the priming effects on the germination of aged seeds at different temperature. The germination percentage of the aged seeds was rapidly dropped starting from 8 days of aging and mean germination time (T$_{50}$) was greatly increased, particularly in germination at 15$^{circ}C$. The germination capacity was greatly restored in the primed seeds after aging, particularly in the seeds of longer aging and germinating at 15$^{circ}C$.>.
