Abstract
The level of polymorphism, genetic variability and relatedness of Convallaria majalis-populations (species native in Poland, under partial legal protection) obtained from three Polish regions and from commercial producers (Polish and Dutch) were studied. In addition the differences between the cultivated plants and those occurring in natural stands were analyzed. Each region was represented by at least 20 populations among which half were collected in natural stands and half from cultivation sites (botanical gardens, private gardens and cemeteries), and compared with samples obtained directly from commercial producers. Seven primer pairs used for AFLP profiling amplified 466 scoreable DNA fragments that were used for multidimensional scaling and clustering. The above analyses make it possible to clearly distinguish among individuals and revealed groups of populations according to their geographic origin. Samples from populations collected in natural stands and cultivated in the same region did not differ from each other significantly. These results suggested that cultivated plants were probably obtained directly from the natural stand and the influence of plant cultures on natural populations was rather small.
