“…Allium ursinum reproduces both generatively and vegetatively by producing daughter bulbs. Although the species tends to reproduce clonally, sexual reproduction is assumed to outrank vegetative reproduction when compared to other herb layer plants (Tutin, 1957;Ernst, 1979;Bierzychudek, 1982;Grime et al, 1988;Oborny et al, 2011). This explains its great intrapopulation genetic differentiation revealed during this study.…”

“…Allium ursinum is a habitat specialist, having a rather narrow range of ecological tolerance (Grime et al, 1988;Kevey, 1977;Oborny et al, 2011). It is strongly confined to deciduous woodlands, mixed beech-fir and beech-spruce forests in Europe (Tutin, 1957;Karpavièiene, 2006;Kovács, 2007), and especially to beech forests (with Fagus sylvatica) in Poland (Rola, 2012).…”

The study investigates the genetic differentiation among two subspecies of Allium ursinum L., namely A. ursinum subsp. ursinum and subsp. ucrainicum as well as their putative hybrid that is represented by individuals with intermediate morphology. Inter-Simple Sequence Repeats (ISSR) were applied to determine the status of intermediate morphotypes in terms of their genetic pattern and to assess the level of genetic variability within and between various populations of A. ursinum. The study comprises 144 specimens from nine populations along the east-west transect in Poland, which includes localities of both subspecies and their putative hybrid. Among the examined populations, 48 bands were amplified, of which 45 were found to be polymorphic. The principal coordinate analysis (PCoA), the neighbour-net analysis and Mantel test showed a strong correlation between genetic variability and geographic distance. Analysis of molecular variance (AMOVA) revealed that a greater proportion of total genetic variation resided within populations rather than among them. The Structure Bayesian clustering analysis revealed the presence of three distinct genetic groups within studied populations, where 'eastern' genotypes correspond to A. ursinum subsp. ucrainicum, and 'western' to subsp. ursinum; whereas the third genetic group has the largest share in the individuals occurring at the border of the distribution ranges of both subspecies. The emergence of the third genetic group is probably an effect of hybridization events occurring within the secondary contact zone. Typical morphologically intermediate populations occur only in a relatively narrow geographical zone, but the hybrid zone revealed by molecular markers is actually much wider than it is suggested by the morphological pattern of individuals. The current distribution pattern of both subspecies of A. ursinum and their hybrid zone is related to the two main directions of postglacial migration of Fagus sylvatica to the area of Poland. The hybrid zone arose as an effect of the secondary contact of two divergent lineages of A. ursinum.K Ke ey y w wo or rd ds s: : Distribution pattern, genetic variability, hybrid zone, intermediate morphotype, ISSR.

“…Although it does not grow at high altitudes (beyond 1.900 m) and in the far North (beyond ca. 64°N), it can be found in natural stands from the Mediterranean region to Scandinavia (Oborny et al, 2011). It is also native to Asia Minor, the Caucasus, and Siberia (Madaus, 1938;Djurdjevic et al, 2004;Oborny et al, 2011;Rola, 2012).…”

“…ucrainicum has smooth pedicels without papillae (Farkas et al, 2012;Rola, 2012). The former is distributed in western and central Europe, whereas the latter in the eastern and south-eastern part of the continent (Oborny et al, 2011;Rola, 2012). The distribution areas of the two subspecies can overlap what results in the existence of transitional forms.…”

One of the rarer problems that occur in growing medicinal and spice plants is ensuring the quality of the propagating material. Germination of seeds of one of these plants, Allium ursinum L., is slow. To improve that, stratification is used. In the experiment, which was carried out in Lithuania in 2016, evaluation of fourand five-week long stratification and the use of alkaline ionized (pH 8.6) water for germination affect for Allium ursinum L. seeds were evaluated. It was found that the above-mentioned intervals for stratification did not affect the beginning of seed germination. Furthermore, one of the possible reasons for slower germination was found, and it was the incidence of seed diseases caused by fungi and bacteria. Allium ursinum L. seeds were affected the most by Penicillium ssp. micromycetes. The longer the period of stratification, the more alkaline ionized water decreased the effect of Mucor ssp. micromycetes.

“…On a phylogenetic tree, these species are in neighboring clades (Hanelt, 1996;Friesen, Fritsch, 2006). A. ursinum also prefers forest habitats, but it requires rather high light conditions, starting to grow before canopy closure, and its distribution is thought to be limited mostly by water availability, as it can grow successfully in open habitats if precipitation is high and evenly distributed or in the vicinity of rivers and streams (Oborny et al, 2011). Thus we can suppose that historically both understorey Allium species were shade-tolerant, but after the loss of functionality of its ndh genes A. paradoxum became a shade-loving species and lost the ability to grow in open habitats.…”
