Miscanthus, a perennial rhizomatous C4 grass, is a potential biomass crop. Its propagation can be made by seed, rhizome and cultured tissue. Propagation by rhizomes or cultured tissues is expensive, while seed propagation is rather simple and cheaper. However, little effort has been made to investigate seed germination, particularly in relation with exogeneous chemicals including plant growth regulators to improve germination. This study was conducted to improve the seed germination of Miscanthus with GA3, NaClO, KNO3 and procloraz. iscanthus sacchariflorus and Miscanthus sinesis seeds were treated with the above chemicals at different concentrations. Decoated seeds were soaked in GA3, NaClO, KNO3, and procloraz solutions. Pretreated 20 Miscanthus seeds were then sown in each petri dish covered with a single layer of Watman filter paper and maintained in the incubation chamber at 33℃/25℃ (day/night). Seed germination were measured every 8 hours. As a result, the best germination was obtained at 250 mg/L GA3, 0.3% NaClO, 1 mM KNO3 and 1 mL/L procloraz solutions.
