In order to improve seed germination rate of Miscanthus sinensis Andersson, this study was conducted on seed weight or time of gathering. Seeds were divided into Heavy, Medium, or Light; dried at 5 ℃ or 25 ℃ in dark condition; watered at 25 ℃ in light condition for 12 hours. As a result, final germination rate was more than 70％ in both Heavy and Medium; was 20％ in Light. Seeds gathered from November to January were subjected to the same treatment. Final germination rate of seeds gathered in November was less than 10％; that in December after the treatment was more than 60％; that in January was more than 50％ regardless of the treatment. Percentage of seeds in Light was 95％ in November, but only about 30％ in December and January. Therefore, a better time of gathering seeds was after December, and removal of lighter seeds might improve germination rate.
