Methods to Create Various Voucher Specimens
The extensive voucher collection of INVAM
accessions is one of the most important assets of the collection. It
provides the physical documentation to define these accessions by
conventional taxonomic criteria and to monitor stability or changes in
morphological properties over time or when propagated in different
hosts, soils, or culture protocols.
The taxonomic benefit is considerable, since about 20% of the current
stocks cannot be assigned Latin binomials, and many others have
uncertain synonymy with described species.
