![]() ![]() The Taguchi method was first used in manufacturing 12, and is now a widely adopted method for efficient experimental design 13. Thus, a broad understanding of the physical and hormonal interactions on Miscanthus seed germination and early growth is important to improve both seed-based multiplication and to identify novel treatments to increase crop establishment on marginal land. Marginal land suffers from a range of possible issues including water and salinity stress that will further exacerbate the problems of seed propagation 11. sinensis can be used for studying germination due to the availability of seed 4, 6, 10. Successful seed-based establishment is difficult 6, particularly because it is proposed that Miscanthus can be planted on marginal land to avoid competing with food crops 7, 8, 9. sacchariflorus or a interspecies hybrid, Miscanthus seeds are harvested from panicles 5. An alternative seed-based propagation would be preferred to increase the scale of production of the crop that is needed to deliver sufficient global impact 3, 4. The crop is currently of a single hybrid ( M × giganteus Greef et Deu (Aksel Olson) 2) and is mostly propagated through inefficient and expensive clonal propagation from rhizomes. Miscanthus is a genus of Poaceae that is being developed for biomass for biorenewable energy and bioproducts, as it is able to produce over 10 t DM ha −1 in a temperate climate 1. The experiment showed how environmental stress impacted germination and how treatments such as gibberellic acid could be used to mitigate stress. This determined an example of a set of optimum conditions for Miscanthus germination and demonstrated how this could change based on fixing one condition. An efficient Taguchi experimental design was used to assess the five factors in combination with the effects of light and seed priming. #Awty quicklinks plusIn this investigation of Miscanthus germination, four hormones plus water stress were investigated and the range over which these factors affect germination was determined. Seed germination is affected by physical and chemical factors that impact germination differently depending on level of exposure. Improved understanding of the limits and biology of germination in Miscanthus species is needed. ![]() Miscanthus is often grown on marginal land adding to the challenge of successfully establishing the crop. Seed-based propagation of new hybrids is being developed, but Miscanthus is difficult to establish from seed especially in the field. Most Miscanthus crop is M × giganteus which is rhizome propagated and therefore difficult to multiply at large scale. The Miscanthus genus of perennial grasses is grown for bioenergy and biorenewable feedstocks. ![]()
