Resumo(s)
Miscanthus x giganteus is a perennial grass, originated from hybridization between M. sinensis
and M. sacchariflorus, identified as a suitable species for commercial production of bioenergy.
Formal information on propagation under Mediterranean condition is, nevertheless, scarce. This
study aimed to evaluate the influence of rhizome cold storage (4O C) and size on Miscanthus
sprouting. Dormant rhizomes were obtained from an experimental plot at Tapada da Ajuda,
Lisbon. Following cold storage, rhizomes were taken to the nursery to run the experiment. The
experiment was conducted in a randomized block design with five replications, where factors
were duration of cold storage (60 and 30 days, and a non-stored control), and length (greater
than or lower than 10 cm) and diameter (higher or lower than 1 cm) of rhizome fragments.
Results were assessed eight weeks after planting, allowing the conclusion that for optimized
plant production under the environmental conditions of the experiment, rhizome fragments
should have a diameter not less than 1 cm, length not less than 10 cm and the method of
breaking dormancy must be cold storage for a period not exceeding four weeks at a
temperature of 4OC.
