Abstract

<abstract abstract-type="main" id="grs12051-abs-0001"> <title>Abstract</title> <p>Species within the genus <italic>Miscanthus</italic> show potential as sustainable bioenergy crops given their low nutrient requirements and high biomass yields. One such species, <italic>Miscanthus sinensis</italic>, has a wide natural distribution and wide phenotypic variation, including its seed germination characteristics. Such characteristics need to be considered, particularly in ensuring plant establishment in regions with harsh winters. Germination rates were measured for 33 <italic>M. sinensis</italic> accessions from different latitudinal regions in Japan. Generally, seeds of accessions from regions of higher latitude germinate earlier than those from more southerly regions under both warm (30°C/20°C day/night) and cool temperature (15°C/10°C day/night) treatments. However, accessions that had lighter seeds germinated late regardless of origin. This survey serves as a basis for identifying <italic>M. sinensis</italic> accessions that are able to germinate early under low‐temperature conditions.</p> </abstract>
