“…Differences in the strength of allelopathic interactions between different species and plant cultivars have also been demonstrated in other studies [24]. According to Kovar et al [24], these differences may be due to the diverse abilities of plants to synthesize allelopathic substances. The largest negative impact on the share of sown grass cultivars was recorded at the following sites (from greater to lesser negative impact): F. ovina 'Espro' , F. rubra ' Areta' , F. arundinacea ' Asterix' , and F. ovina 'Pintor' .…”

The aim of the study was to assess the impact of cut vegetative shoots of chosen lawn grass cultivars of Festuca being left on the lawn sward surface on the species composition, sodding and appearance, and over-wintering of the lawn. The influence of decomposing biomass was studied in a field experiment between 2008 and 2014. Each cultivar was sown as a monoculture on microplots with an area of 1 m2. The control consisted of sites from which the cut sward had been removed immediately after cutting.The results obtained may indicate an allelopathic effect of the cut sward of the cultivars left on the lawn surfaces. The following had the most negative effects on the species composition of the lawn sward (from greater to lesser negative impact): F. ovina ‘Espro’, F. rubra ‘Areta’, F. arundinacea ‘Asterix’, and F. ovina ‘Pintor’. With the exception of ‘Espro’, these cultivars also limited the presence of dicotyledonous plants in the lawn sward. The cover of dicotyledonous plants and other unsown grasses was also recorded on the sites with F. rubra ‘Olivia’ and ‘Nimba’. The greatest negative influence on the sodding of the lawn swards was demonstrated by the latter F. rubra cultivar, whereas F. ovina ‘Espro’ had the greatest negative influence on the appearance. However, no differences were found in assessments of over-wintering of the cultivars at the study sites. However, taking into account the scale of these impacts on the characteristics evaluated, the cultivars of Festuca species tested can be recommended for extensive use, where a cut sward can be left on the surface of the lawn. Some caution in this respect is recommended when it comes to F. ovina ‘Espro’ and F. rubra ‘Areta’ and ‘Nimba’.

From the first half of the XX century, the maritime Antarctic was a region with high regional warming rates. At the beginning of the XXI century, regional warming strongly slowed down, but during the next twenty years the near-surface temperatures and mean annual precipitation at the Antarctic Peninsula will most probably increase. Higher temperatures and precipitation make the conditions in the maritime Antarctic more favourable for plants, including invasive species. Moreover, the increasing number of Antarctic tourists unintentionally transport thousands of seeds to the Antarctic on their clothes and equipment. In such circumstances, it is important to evaluate possible defensive mechanisms of native plant species, including their allelopathic potential. The objective of this study was to evaluate the allelopathic potential and cytostatic activity of Sanionia georgicouncinata. This species is widespread in the maritime Antarctic and is one of the most abundant moss species on the Argentine Islands (Wilhelm Archipelago). Seeds of cucumber Cucumis sativus, radish Raphanus raphanistrum subsp. sativus, wheat Triticum vulgare, and amaranth Amaranthus paniculatus were used as bioassay species. Fresh green biomass of S. georgicouncinata was used to prepare aqueous extracts with 1 : 10, 1 : 50, and 1 : 100 plant to water ratios. The average root length of wheat sprouts and cucumber sprouts in distilled water did not differ significantly from those in plant extracts. The root length of radish sprouts in 1 : 50 plant extract was significantly shorter than in distilled water. Meanwhile, in 1 : 50 and 1 : 100 water extracts, roots of amaranth plants were significantly longer than in water. The number of lateral roots of cucumber sprouts in water and studied aqueous extracts varied from 1 to 6 with medians from 3 to 4. The medians of control (distilled water) and sample groups (aqueous extracts) did not differ significantly, but only 38.1 ± 6.1% of cucumber sprouts developed lateral roots in the 1 : 10 aqueous extract of S. georgicouncinata, and even less – 28.3 ± 7.5% in the 1 : 50 aqueous extract. The results of this study show that the allelopathic potential of S. georgicouncinata is low. However, a significant cytostatic activity of the studied extracts shows that this species may still affect other plants and animals. Further research is needed to evaluate the impact of the studied extracts on root growth and germination of the invasive plants, particularly Poa annua.
