Effect of Seed Priming Treatment on the germination of Sesame

This experiment was conducted to find out optimum priming treatment conditions to the sesame seed as a preliminary study for enhancing sesame germination properties. Effective priming agents and concentrations for sesame seed were K3PO4, 200 mM and PEG6000, -1.0 MPa respectively. Optimum priming temperature and duration were 15℃, 4 days in view of germination speed and germination percentage. PEG6000 with -1.0 MPa was selected as an efficient priming treatment condition at 15℃, 4 days. This study suggested that priming treatment to sesame seed would be an effective technique enhancing sesame seed germination and shortening time to the T50 at the field condition, but the efficiency of priming treatments to the sesame seed would be strongly dependent on individual or integrated conditions of priming agent, concent-ration, temperature and duration etc.
