Germination ability of the rhizomes of giant reed
(Arundo donax L.). Study on the size limits of the propagation
material. Giant reed (Arundo donax L.) is a perennial rhizomatous
grass currently pointed out as an alternative crop for
the bioenergy production. Arundo is propagated by vegetative
cuttings or by rhizomes. This latter is the solution allows higher
margins of reliability for the successful cultivation in a short time.
The establishment of a plantation represents one of main voice of
the cultivation costs and influences the future productivity of the
crop. Therefore, CRA-ING has conducted a study in order to gain
useful information about the germination ability of the rhizomes
of different sizes and to evaluate the adaptability of the crop to
the soil and climatic conditions of Central Italy The research
carried out at Monterotondo has shown that the giant reed can
be propagated by rhizomes smaller than 10 cm. Furthermore,
the data evidenced as these ones are able to bridge the gap of
development initially present from the larger ones. In perspective
such results would demonstrate that a further space exist for the
lowering of transplant cost.
