Opis:
One of the factors limiting crop growth is weeds. The weeds lead to a reduced performance of the crops. Chemical control methods are considered appropriate for controlling weeds. Therefore, in the fight to control weeds in triticale, the performance of the dual-purpose herbicide sulfosulfuron(Apirus®), mesosulfuron + idosulfuron(Atlantis®), metsulfuron methyl+sulfosulfuron(Total®) with surfactant and isoproton + diflufenican(Panther®) from the sulfonylurea group, and narrow leaf herbicides clodinafobpropargyl( Topik®), pinoxaden(New Axial®), diclofop-methyl(Iloxan®), pinoxaden + clodinafob-propagyl (Traxos ®), fenoxaprop-pethyl + mefen-pyper-d-ethyl(PumaSuper®), tralkoksidim(Grasb®) with 1 liter oil, flam-prop-m-isopropyl(Suffix BW®), and control treatment without herbicides were evaluated. The test was carried out in a randomized complete block design with four replications. Spraying was carried out using a back sprayer. For evaluation of ocular damage, the European Weed Research Council (EWRC) standard method was used. According to the performed studies, the narrow leaves of wild oat and barnyard grass were the dominant weeds. Results showed that all herbicide, except the herbicide tralkoksidim, were effective in weed control. The triticale yield was maintained with the use of these herbicides and none of herbicide had an adverse effect on the crop. In the first weeks of herbicide use, the triticale leaves appeared pale but this problem resolved over time. It seems that the herbicides discussed in this paper can be used on the triticale plant.

Opis:
The aim of the work was to estimate the specific role that Central European botanic gardens play in the dispersal of alien plants, which results from the wide variety of plants cultivated in the gardens and regular international exchange of plant material between these institutions. We compared the results of recent field studies (in eight Polish botanic gardens) and a review of older literature data and herbarium collections (from Central European botanic gardens). We found that in Poland the proportion of botanic garden escapes was lower (3%) than would be expected from the "tens rule". Botanic gardens have played a considerable role in the development of the synanthropic flora of Central Europe in the last 200 years. We determined a group of species introduced through a network of botanic gardens and propose 5 theoretical patterns to describe the mode and pathways of the early stages of introduction of these species.

Opis:
Riparian zones in two rivers in southern Poland were studied in terms of species composition and soil parameters in patches dominated by three knotweed taxa (Fallopia japonica, F. sachalinensis and the hybrid F. ×bohemica). The main purpose was to detect any differences in species diversity, environmental conditions and in the impact of the three Fallopia spp. on resident species. Fieldwork was conducted in spring and summer in 30 invaded plots (in total 90 subplots). It was demonstrated that vegetation dominated by particular knotweed taxa differed in response to soil pH and ammonium, nitrate, and magnesium content. Fallopia spp. (living plants and necromass) had a stronger negative impact on the cover and species diversity of the resident species in summer in comparison with spring. Vegetation patches differed significantly in species composition in relation to the knotweed taxa present. These differences may be the consequence of the differentiated biotopic requirements of Fallopia taxa and the coexisting plants, or to the different impact of the knotweed taxa on the resident species.

Opis:
The article presents the results of complex laboratory investigations on the biological and biomechanical ways of control of Melanoides tuberculata (Müller 1774) and Tarebia granifera (Lamarck, 1822) molluscs in simulated conditions close to the conditions of the cooling pond of the Zaporizhia Nuclear Power Plant. It was determined that molluscs have naturalized in the Zaporizhia Nuclear Power Plant cooling pond, quickly increased their number and created a threat to hydraulic structures. Taking into account biological features of Thiaridae mollusks and technical and ecological features of Zaporizhia NPP, we carried out a series of experiments using biological control measures (the use of predatory species of hydrobionts) and mechanical means for controlling mollusks. Representatives of different taxons of the Animalia Kingdom were selected as predatory species of hydrobionts, which potentially can consume gastropods: Mollusca, Crustaceans and Fish. It has been found experimentally that the use of marbled crayfish Procambarus virginalis (Lyko, 2017), pumpkinseed Lepomis gibbosus (Linnaeus, 1758) and Botia lohachata Chaudhuri, 1912 has not given positive results in the development of measures to control the number of molluscs. Positive results were obtained in a series of experiments with predatory mollusc assassin snail Clea helena (von dem Busch, 1847), but it was noted that in the presence of more accessible feeds, assassin snail Clea helena (von dem Busch, 1847) consumes smaller quantities of Thiaridae mollusks. The most successful results we obtained in experiments with traps for molluscs. We have developed experimental constructions of traps with lower and upper inlets that act as mollusk accumulator and can be installed in the coastal zone of the reservoir and Zaporizhia NPP cooling system channels for reducing the number of reproductive individuals of Melanoides tuberculata (Müller 1774) and Tarebia granifera (Lamarck, 1822). The most effective were the traps with the lower inlet to which the mollusks could get faster. In order to attract mollusks to traps, we have conducted studies on the use of feed baits for molluscs. Most effectively, molluscs fell into traps that contained lime feed, feedstock sunflower oil and anise oil. The most effective among mollusks was the bait with the addition of anise oil. During the exposure, traps with anise bait traps accumulated 14.1% of molluscs. The conducted researches can serve as the basis for the development of biomelioration measures aimed at reducing the negative impact of accidental introduction of new species of molluscs into technical reservoirs of strategic importance.

Opis:
The paper presents the results of several years investigations (2003-2007) on two invaders: the Himalayans Impatiens glandulifera and Asiatic Reynoutria japonica. The Sudety Mountains and their national parks are under strong pressure of both species, threatening the local vegetation. The four-year investigations have been carried out in field, glasshouse and in laboratory. Invasive species have their peculiar life histories which help them to occupy new areas. Those are above all the specific generative reproduction strategies (Impatiens) or vegetative reproduction strategies (Reynoutria). Both strategies secure the reproductive success and to capture more and more highly situated areas of the mountains. Very significant characteristics connected with the expansion of invaders is the excessively over and above the average production of seeds (Impatiens) and a huge annual increment aboveground biomass (Reynoutria). The investigated invasive species are probably not equipped with influence of allelopatic type as of greater importance is their competitive strength. The invaders can eliminate a part of the early spring flora belonging to the geophyte group and impoverish the regional biological diversity. Both the invasive plants enter also into some moist mountain forest communities.
