“…The aim of the research described in this paper was to assess the extent of the allelopathic effect of Scots pine on the test plant. The plant selected for tests was white mustard (Sinapsis alba L.), proposed previously by others authors as a receiver species (or acceptor, or test plant) (Csiszár 2009;Csiszár et al 2013, Tunaitienë et al 2017. The current research compared the impact of leachates obtained from different Scots pine clones on the test plant.…”

Identification of Pinus sylvestris clones with highest and lowest allelopathic potential

Allelopathy is a kind of interaction between plants in which the inhibitory effect on growth and germination can play an important role during the struggle for existence in interspecific competition. The species (or clone of one species) with a higher allelopathic potential might win the competition and place themselves in a better biosocial position for growth. Also, the clones with a lower allopathic potential might be useful in agroforestry, e.g. as trees useful for shading the crops. The allelopathic potential of Scots pine (Pinus sylvestris L.), the tree species with a wide range of distribution in Europe and of great economic importance, was estimated in this study. To this end, needles from trees growing in a clonal seed orchard were collected and used as a material to obtain water leachates. The leachates were diluted to 25 and 50% and used in allelopathy tests. The differences between potentials of leachates from Scots pine clones to inhibit germination and growth of the test plant (Sinapis alba L. cv. Borowska) were assessed. The clones 1702 and 1703 were characterized as highly allelopathic, with the potential confirmed in two independent allelopathic tests. The clones 355 and 2209 were characterized as clones with a moderate allopathic potential. The possibility of selecting clones with the known allelopathic potential for the successful use in forestry was discussed.

“…Thirdly, our study demonstrated that habitat differentiation is reflected in the variation and genetic structure of A. aristatum populations occurring at the non-native range limit. These results refer to the oftendiscussed problem of interactions between an alien species and habitats it colonizes beyond its natural range limit (among others, Dietz and Edwards 2006;Riis et al 2010;Erfmeier et al 2011;Pahl et al 2013;Tunaitien_ e et al 2017). Previous studies of plants occurring in habitats differing in use intensity indicate three possible patterns of population genetic diversity:…”

“…(1) plants in disturbed habitats have higher genotypic and genetic diversity than in stable habitats (Koppitz et al 2000;Xie et al 2001;Lambertini et al 2008); (2) there are no significant differences between the genotypic and genetic diversity of populations occurring in habitats with different disturbance regimes (Solé et al 2004); and (3) populations in stable habitats are more differentiated than populations in disturbed habitats (Trtikova et al 2011;Tunaitien_ e et al 2017).…”

Anthoxanthum aristatum Boiss. is native to southern and western Europe and North Africa. In Central Europe this species is recognized as invasive. Its ability to colonize various habitats may result from a high level of polymorphic isozyme loci and high morphological variability. The aim of this study was to recognize the degree of genetic diversity of the studied invasive species at its non-native range limit using molecular markers. The examined plant material consisted of 70 samples collected from 7 populations originating from various habitats: arable fields, recently abandoned field and sandy grassland. Ninety-six the Directed Amplification of Minisatellite-region DNA loci and 82 Sequence-Related Amplified Polymorphism loci were detected. The genetic diversity at the species level was high. The majority of genetic variation was present within populations (68% and 66%), while the remaining molecular variation was distributed among populations within and among habitat types. Specimens originating from sandy grassland populations were grouped together in one cluster that was genetically distinct from the arable field and fallow populations. The high genetic diversity populations at the A. aristatum non-native range limit in Central Europe and their marked diversity in arable field and sandy grassland habitats suggest that this species may systematically cross both geographical and ecological barriers.

“…Generally , intermediate levels of disturbance improve the genetic diversity of clone plants, providing greater recruitment of new genes into the population (McMahon et al., 2017). However, Tunaitien et al. (2017) found that population diversity parameters of Erigeron annuus did not significantly differ between stable habitats and disturbed regions.…”

“…The influence of disturbance on genetic structure results from the imposed environmental and demographic changes, which are closely related to the species responses to habitat suitability, leading to accelerate its evolutional process (Banks et al., 2013). Therefore, some presumed that genetic differentiation could be associated with founder effects or different selection pressures under disturbed habitats (Tunaitien et al., 2017). The population structure of Ranunculus ficaria under heterogenic habitats provides a good example of the impact of selection pressure.…”

Effect of Human Disturbance on Genetic Structure of Rare and Endangered Paphiopedilum micranthum Implied the Habitat Status

Seven populations of Paphiopedilum micranthum from Southeast China were used to assess the influence of human disturbance on genetic structure through analysis with sequence-related amplified polymorphism technology. The results indicated that there was high genetic diversity at species level ( p = 81.25%; I = 0.3709) and a significantly higher differentiation level compared to that those of other outcrossing orchid species, and that moderately disturbed populations sustained higher genetic diversity indexes than the natural populations. This study revealed that human disturbance and population size did not significantly affect the populations’ genetic diversity but aggravated their differentiation. This may suggest that the habitat had a much greater influence on genetic variation.
