A seed germination protocol for Miscanthus sinensis Andersson is not available. Our objectives were to evaluate requirements for germination. Eight seed lots (four varieties and two production years) were germinated at four regimes of two alternating temperatures: 15/25, 15/30, 20/30, and 16/22 degrees C for 16 and 8 h, respectively; with or without light; and with gibberellic acid (GA(3)), KNO3, prechill (5 degrees C), or water (control) treatments (32 treatment combinations). Fresh seeds (from 2011) germinated best at the combination of 20/30 degrees C, whereas seeds from 2010 were not affected by temperature. This difference may suggest the presence of dormancy, as seed germination was enhanced by prechill and GA(3). Light was not a significant factor. These results provide a basis for developing a standard germination protocol.
