“…Opposed to present study, Šćepanović et al (2007) kept plant material for 96 hours. Again, the difference from Šćepanović et al (2007) and Pacanoski et al (2014) was also recorded for different parts of donor species (individual parts/whole plant). In studies where the same testspecies were used, the differences in the effect could be attributed to the different cultivars of the test-species.…”

At the global level, the invasion of alien organisms is considered the second largest threat to biodiversity. The assumption is that the high allelopathic potential is one of the features that helps invasive plant species to spread to new areas. Allelopathic potential of 8 invasive plant species (donor species) and their impact on test-species was determined in the study. Donor species were velvetleaf (Abutilon theophrasti Med.), ragweed (Ambrosia elatior L.), jimsonweed (Datura stramonium L.), common cocklebur (Xanthium strumarium L.), tree of heaven (Ailanthus altissima (Mill.) Swingle), indigo bush (Amorpha fruticosa L.), Japanese knotweed (Reynoutria japonica Houtt.) and giant goldenrod (Solidago gigantea Aiton). Three cultivated plant species from 3 different plant families were used as test-species. Test-species were: oat (Avena sativa L.), oilseed rape (Brassica napus subsp. oleifera) and sunflower (Helianthus annuus L.). Water extracts made of whole plants of donor species were applied to the seeds of the test-species. High allelopathic potential was proven for all species included in experiment. Allelopathic effects were exclusively negative. Impact on germination for all species was much lower in relation to the impact on the radicle and shoot length of the test-species. Perennial donor species had a stronger allelopathic potential than annual donor species. Tree of heaven was the species with the strongest allelopathic potential. Its extracts inhibited germination, radicle and shoot length of oilseed rape by 19%, 94.88% and 98.91% respectively. Keywords SažetakNa globalnoj razini, invazije alohtonih organizama predstavljaju drugu najveću prijetnju bioraznolikosti. Pretpostavka je da je visok alelopatski potencijal jedna od značajki koja pomaže invazivnim biljnim vrstama u širenju na nova područja. U radu je određen alelopatski potencijal 8 invazivnih biljnih vrsta (donor vrsta) i njihov učinak na test-vrste. Donor vrste su bile europski mračnjak (Abutilon theophrasti Med.), pelinolisni limundžik (Ambrosia elatior L.), bijeli kužnjak (Datura stramonium L.), dikica (Xanthium strumarium L.), pajasen (Ailanthus altissima (Mill.) Swingle), amorfa (Amorpha fruticosa L.), japanski dvornik (Reynoutria japonica Houtt.), velika zlatnica (Solidago gigantea Aiton). Kao test-biljke korištene su 3 kultivirane biljne vrste iz 3 različite biljne porodice: zob (Avena sativa L.), uljana repica (Brassica napus L.) i suncokret (Helianthus annuus L.). Vodeni ekstrakti napravljeni od cijelih biljaka donor vrsta aplicirani su na sjeme test-vrsta. Dokazan je visok alelopatski potencijal za sve vrste uključene u istraživanje. Alelopatski učinci bili su isključivo negativni. Učinak na klijavost svih vrsta mnogo je manji u odnosu na učinak na duljinu korjenčića i klica test-vrsta. Kod višegodišnjih donor vrsta zabilježen je jači alelopatski potencijal nego kod jednogodišnjih donor vrsta. Pajasen (Ailanthus altissima (Mill.) je vrsta s najjačim alelopatskim potencijalom. Njegovi ekstrakti inhibirali su klijanje, duljinu...

The aim of this study was to determine the influence of different pH values of water solution (pH 4.5, 5.5, 6.5, 7.5 and 8.5) and temperatures (10, 15 and 20 ºC) on fibre flax seed germination and seedlings morphological characteristic (seedling root and stem length and total seedling length). The study was conducted in the controlled conditions by rolled filter paper in 4 replicates for 7 days. The average germination rate of flax seed was 84%. The highest germination rate was found at 20 ºC (88%) which was very significant (P<0.01) as compared to germination rate at 10 ºC where it was decreased by 9%. The highest share of normal seedlings was determined at pH 5.5 (70%) and the lowest at pH 8.5 (59%).There was no statistically significant influence of different pH on morphological characteristic of fibre flax seedlings (seedling root and stem length and total seedling length). The statistically significant difference (P<0.01) was determined in the length of the seedlings depending on the temperature, whereby after 7 days the largest seedlings were developed at 20 ºC (14.4 cm) and the shortest at 10 ºC (2.1 cm). In general, the lowest pH value (4.5) as well as the highest pH value (8.5) in this study resulted in a lower share of normal and healthy seedlings (63% and 59% respectively) and compared with seedlings of other pH values they developed a smaller root and stem.

“…Domuz pıtrağı yapraklarının geniş olması, 15-100 cm boylanabilmeleri ve çimlendikten sonra hızlı bir gelişim gösterebilme yeteneklerinden dolayı ayçiçeği ile rekabet gücü çok yüksektir.

Determination of the yield reductions and economic threshold caused by common cocklebur (Xanthium strumarium L.) in sunflower production fields in AnkaraHigh nutritive content, using in various industrial sectors and adaptation of various regions of sunflower (Helianthus annuus L.) have allowed of cultivation and consumption at high scale. One of the important problems of sunflower prevalently cultivated in Marmara and Central Anatolia Regions is weeds. Among the weeds, common cocklebur (Xanthium strumarium L.) is very important because it has a competitive character, and there is only one herbicide registered to control this weed. The field study was carried out to determine the economic threshold of common cocklebur in sunflower from 2013 to 2015 in Ankara. According to the three-year study values, the highest sunflower plant length (138.33 cm), head diameter (14.4 cm) and 1000-seed weight (85.03 g) were obtained from the control parcels while the lowest plant length (104.17 cm), head diameter (10.41 cm) and 1000-seed weight (62.81 g) were taken from the parcels consisted of 16 common cocklebur plants.The economic thresholds were calculated using the current sunflower price and the herbicide, imazamox (
