While Ardisia crenata Sims. recently has been used increasingly as an ornamental plant, It is endangered in natural forest. The optimum treatments of the various concentrations priming agents to improve seed viability and germination of A. crenata (ornamental plant) were also estimated. Germinability was significantly when the seeds of A. crenata was soaked in PEG solution at 15oC for 4 days, the optimum treatment for improving germination of A. crenata was observed when the tested seeds was soaked in −0.5 MPa of PEG solution in 92%. Overall results would be useful means for propagation and production of A. crenata.
