seed quality improving by priming to increase crops growth and yield

there are several methods to increase crops yield, including use of high quality seeds. seed priming is a simple and low-cost method to increase seed quality, if be done right, will lead to increasing plant performance and yield. seed priming treatment applied before planting to enhance germination parameters, seedling establishment and etc. primed seeds get some physiological and biochemical changes before sowing that these changes will express in produced seedling and also whole plants. benefits of priming including more and rapid germination, better seedling establishment, utilization of environmental factors, and resistance to adverse environmental conditions, better compete with weeds, earliness and increase quality and quantity of the products. despite these positive features, the biggest flaw is that primed seeds cannot be stored and should be planted immediately after priming. it is a reminder that important parameters such as osmotic potential of priming, priming period, the temperature of the priming solution, priming aeration, control of pathogens during priming and drying of seeds after priming are factors that affect efficacy of this technique.
