“…Higher concentrations of Salvia extract generally result in greater inhibitory potential (Bisio et. al., 2010, Erez and Fidan, 2015, Ravlić et al, 2016 which is in accordance with results of our study. Ravlić et al (2016) reported reduction in germination of hoary cress (Lepidium draba L.) up to 100% with common sage (Salvia officinalis L.) extracts from dry biomass compared to 25.7% with extracts from fresh biomass.…”

“…Similarly, Bouajaj et al (2013) reported negative effect of common sage (S. officinalis) essential oil on root length of lettuce. Inhibition of shoot length was also reported in other studies, as well as reductions in chlorophyll content in treatments with extracts from different Salvia species (Bisio et al, 2010, Ravlić et al, 2016. Salvia extracts are rich in phenolic compounds and flavonoids (Erez and Fidan, 2015;Grzegorczyk-Karolak and Kiss, 2018), while major components of Salvia essential oils and hydrosols include β-thujone, α-thujone, camphor and 1,8-cineole (Bouajaj et al, 2013, Matković et al, 2018, Politi et al, 2022.…”

Medicinal and aromatic plants with allelopathic effect are a potential source of natural herbicides. The experiment was conducted in order to assess herbicidal potential of meadow sage (Salvia pratensis L.) on germination and growth of weed species velvetleaf (Abutilon theophrasti Med.) and common corn-cockle (Agrostemma githago L.). Water extracts from S. pratensis dry biomass in different concentrations were evaluated under controlled laboratory conditions in Petri dish bioassay. Herbicidal effect of S. pratensis extracts depended on the extract concentration and weed species. In general, higher concentrations of water extract showed greater negative effect on germination and growth parameters of weed seedlings. A. githago had greater sensitivity to S. pratensis extracts with reductions in germination and seedlings growth up to 100% in treatments with 7.5% and 10% extract concentrations. A. theophrasti germination was not affected by water extracts, however, substantial reductions of root and shoot length as well as fresh weight of seedlings were recorded. S. pratensis proved as promising plant species for further studies.

“…Differences in inhibitory effects of the extracts made from fresh or dry weed biomass of C. epithymum on seed germination of the test plants can be attributed to diffusion of soluble allelochemicals during extraction of fresh and dry weed biomass (Dhima et al, 2009;Konstantinović et al, 2014;Ravlić et al, 2016). (2016) inferring that allelochemicals are released during extraction from fresh weed biomass, which does not occur during extraction from dry weed biomass.…”

Allelopathic effects of cold water extracts of Cuscuta epithymum L. on seed germination and initial development of Medicago sativa L. varieties were investigated under laboratory conditions at the Institute of Forage Crops, Pleven, during 2016-2017. It was found that the water extracts from dry biomass of C. epithymum had a considerably stronger inhibitory effect on the studied M. sativa varieties (IR 32.7-100.0 %), as compared to the extracts of fresh biomass (IR 0.2-40.5%). Depending on the kind of C. epithymum extract (fresh or dry parasitic weed biomass), IRs for seed germination of the tested M. sativa varieties could be conventionally classified into five groups: 1) seed germination stimulation,-1.4%-extracts from fresh biomass affecting the variety "Multifoliolate"; 2) seed germination inhibition of 0.1-10%-extracts prepared from fresh biomass affecting the varieties "Prista 3", "Pleven 6", "Prista 5" and "Obnova"; 3) seed germination inhibition of 11-20%-extracts from fresh biomass affecting the varieties "Roly" and "Victoria"; 4) seed germination inhibition of 30-45%-extracts from dry biomass affecting the variety "Multifoliolate"; 5) seed germination inhibition of 46-60%-extracts from dry biomass affecting the varieties "Prista 5", "Prista 3", "Victoria", "Roly", "Dara", "Pleven 6" and "Obnova". The varieties "Victoria", "Prista 5" and "Multifoliolate" of M. sativa possess some allelopathic tolerance because their germination indexes (GI) range from 80.5 to 88.7 % for the extracts prepared from fresh weed biomass of C. epithymum, and from 47.1 to 48.6% for the extracts from dry weed biomass, compared to control treatment. These varieties can be used as components in future breeding programmes.

“…Rice [5] defined allelopathy as any direct or indirect effect, positive or negative, on the development of an acceptor plant, or microorganisms, as a consequence of the release of secondary metabolites to the environment by a donor organism. In seeds, it has been documented that exudates generated during germination can inhibit the seed germination of other species [6][7][8][9][10]. For example, some seeds possess non-protein amino acids that function as inhibitors of basic metabolism [11,12], interfering with auxin transport, protein synthesis, polypeptide elongation [13] and root development [14].…”

Background Density in inter and intraspecific plant-plant interactions affects the action modes of allelopathy (autotoxicity, negative and positive allelopathy). Some seeds exude compounds that inhibit the germination of others. Ipomoea murucoides and I. pauciflora are sympatric tree species that form patches at the local scale where one or the other dominates, possibly due to allelopathy in the seeds. The objective of this study was to determine the possible density-dependence of the allelopathic effect among seeds of these species through the measure of seed germination and seedling emergence. Methods In both species, allelopathy was measured as: a) germination in mixed sowing of both species at different proportions, b) germination in single-species trials at different densities after adding seed extracts of both species, and c) seedling emergence in seed mixtures of both species sown at different proportions beneath canopies of the two Ipomoea species. Results Seed germination of I. murucoides was increased by the presence of I. pauciflora and diminished at higher densities of its own seeds; however, seed germination of I. pauciflora was not affected by the presence of I. murucoides seeds. The addition of extracts (either from conspecifics or congeneric) diminished the germination of both species and at higher seed densities the germination was lower. Seedling emergence did not depend on the species under which the seeds were sown nor on the density of the seeds. Conclusions The germination experiments evidenced positive allelopathy and/or autotoxicity, while there was no evidence of allelopathic effects in seedling emergence. The allelopathic activity is reported in the seeds of these species for the first time.
