Sesame which is usually planted in arid and
semi-arid regions is an annual oilseed crop
cultivated for centuries, particularly in the
developing countries of Asia and Africa, for its high
content of both excellent quality edible oil (42-54%)
and protein (22- 25%). High quality seed is
considered to be one of the most important factors
in crop production. One of the components of seed
quality is seed vigor (Hampton, 1995). Accelerated
aging of seed is a treatment uses to assess storage
quality, germination characteristics by simulation natural aging conditions for different crops
(Galeshchi et al., 2002; Moradi et al., 2009).
Accelerated ageing of sunflower seeds, which
consists of placing seeds at high temperature and
relative humidity, is associated with a progressive
decrease in seed germinability (Bailly et al., 1996).
Priming is a seed improving and invigoration
technique applied before planting and can increase
rate and percent of germination and emergence
especially under stress conditions like salinity,
drought and high temperature stresses (Sedghi et
