Accessions

Ex situ MAP collections
• Botanical gardens
Collections of both wild and cultivated MAP species are maintained in botanical gardens.
Six of the numerous botanical gardens in Poland maintain large MAP collections and offer
the seeds of those plants according to the Index Seminum. These are mainly the seeds of
plants cultivated in those gardens (1765 accessions from 110 families). However some
botanical gardens (e.g. Botanical Garden of Medicinal Plants, University of Medicine,
Wrocław) also possess seeds of wild medicinal plants collected from natural sites
(208 accessions) (Table 2).
• Warsaw Agricultural University
The Department of Vegetable and Medicinal Plants, Warsaw Agricultural University also
maintains ex situ collections of some MAP species (Table 3). The collected accessions differ
both in quantitative and qualitative traits, e.g. content and composition of biologically active
compounds (Osińska 2000; Węglarz et al. 2002) (Tables 3 and 4).
