Opis:: Sprouts consumption is increasing worldwide due to their nutritional and health benefits. However, they can be sources of foodborne bacterial diseases, including sprout-related outbreaks caused primarily by Shiga toxin-producing Escherichia coli and Salmonella spp. The aim of this study was to determine the efficacy of a dried sea buckthorn fruit extract in sanitization of contaminated radish seeds. The efficacy of 15-min seed treatment and 3-h soaking in the extract solution was evaluated in comparison to the treatment with 20,000 mg/L calcium hypochlorite, recommended by the U.S. Food and Drug Administration. The effect of the sea buckthorn fruit extract on radish seed germination capacity and the profile of phenolic compounds in the extract were also determined. Decontamination effect of the extract after a 15-min seed treatment ranged from 72.1% against Staphylococcus aureus to 93.0% against Listeria monocytogenes and was higher than that of active chlorine against E. coli, S. aureus and Salmonella enterica. Soaking seeds for 3 h in the extract increased the decontamination efficiency only against S. aureus (81.9%). Compared to water, after 4 days of sprouting, no significant differences were found in radish seed germination capacity and the length of roots and hypocotyls of sprouts. The sea buckthorn fruit extract had a high content of phenolic compounds, namely isorhamnetin 3-rhamnosylglucoside (12.99 mg/L), isorhamnetin 3-rutinoside (8.25 mg/L), protocatechuic acid (5.43 mg/L), isorhamnetin 3-glucoside (3.41 mg/L), and gallic acid (3.36 mg/L). The extract can be used as a substance limiting bacterial contamination of radish seeds and, as a result, sprouts, as well as a valuable source of phenolic compounds.

Opis:: By creating highly productive phytobiomes, selection of new types of biostimulants on the basis of organic substances and microorganism has a decisive role. It could be done by taking into account natural and climatic peculiarities of the region. The article described the importance of sugar sorghum and substantiates the introduction of an adaptive variety to increase the productivity of fodder sorghum and the best option of using growth biostimulants. The results of evaluating the effectiveness of growth biostimulants under laboratory conditions on the main nutritional valuable traits were presented. The treatment of optimal parameters of sugar sorghum seeds with biostimulants in the Research laboratory "Industrial biotechnology" of M. Auezov South Kazakhstan University was determined. It was shown that the "Azotofertil" biostimulator has a high efficiency in pre-sowing seed treatment. For comparative evaluation of potentialities of new biostimulant, MERS biostimulant adapted to climatic conditions was chosen. According to research results, both biostimulants showed high efficiency for seed pre-sowing treatment. The best concentration for treatment of planting material was established. Energy of germination, swelling and the number of germination of seeds of sugar sorghum variety Kazakhstan-16 were determined. In evaluating the activity of biostimulants for efficiency, the dynamics of their friendly germination was traced. At 4% concentration and temperature above 14 °C, the advantage of "Azotofertil" biostimulator based on Azotobacter chroococcum strain was proven. Seeds of sugar sorghum variety Kazakhstan-16 showed the best results with 96 ± 3% germination.

Opis:: Germinating seeds constitute a natural source of substances that can be used to supplement food and increase its functionality. In this work, red mizuna (Brassica rapa L. var. nipposinica) in the form of sprouts was used as research materials. The main goal of this study was to investigate the effect of germination time on the phytochemical profile of health-promoting compounds in red mizuna sprouts. The metabolomic profile of water-methanol mizuna sprout extracts was analyzed by UPLCESI-MS/MS. In this work qualitative analysis of four mizuna sprout extracts collected after 4, 6, 8 and 11 days after sowing was carried out. Moreover, the phytochemical characterization of red mizuna seeds before the sprouting process was undertaken. Thirty-nine compounds were interpreted and the fact of the variability of the qualitative profile over time was confirmed. This is the first report to provide information on the differences in the phytochemical profile between sprouts of red mizuna subjected to the influence of germination time, in order to determine the harvesting and consumption maturity of the tested plant material.

Opis:: Composting is commonly used for waste management and the evaluation of its quality is important for successful application. Seed germination test is commonly adopted due to its capacity to examine the toxicity level of compost. The seed test is usually evaluated on the final product and the results can vary with the different methods and the type of seed utilized. In this study, the evolution of seed germination tests during the composting process of municipal waste (MSW) mixed with poultry manure (PM) of two species tomato and sugar beet was examined. The impact of compost water extracts on seed germination and plant primary root growth for each sampling was reported. The chemical parametrs were evaluated on the final product. Results show that mixture C1 with a higher amount of municipal waste gave less compost yield than mixture C2. After 35 days of composting, the compost was phytotoxic for tomato and sugar beet seeds. The seeds of the two cultures reacted differently to the same compost. The compost could stimulate sugar beet germination at days 110, 140, 180, 212 and 252. Seed germination of sugar beet was increased and delayed by one day by the compost stabilized and mature as compared with the control.

Opis:: Among a number of climate-related factors, moisture has the greatest impact on crop productivity. In recent years, certain changes have been observed under conditions of the Forest-Steppe of Ukraine with regard to precipitation – from low to in some cases – abnormally high, which requires the study of their impact on the yield and safety of cereal grain for its forecasted production. The article examined the effect of a high level of soil moisture (256.2–272.5 mm) and a low level (47.4–52.3 mm) during the growing season (germination→earing) of spring barley grain on the accumulation of heavy metals in it and its productivity under the conditions of gray forest soils of the Right Bank Forest Steppe of Ukraine. Spring barley varieties Helios and Caesar were selected for the research. A decrease in the accumulation coefficient at a high level of soil moisture (256.6–272.5 mm) in spring barley grain Pb from 8.3% to 11.3%, Cd – from 35.0% to 35.5%, Zn was established – by 15% and Cu – from 11.2% to 16.6% compared to the low level of soil moisture (47.1 mm – 53.3 mm). At the same time, it was found that with a high level of soil moisture, there is a decrease in the yield of Helios and Caesar spring barley by 18.0% and 14.1%, respectively.

Opis:: Podstawowymi parametrami wartości siewnej są: zdolność kiełkowania. czystość, zawartość nasion obcych oraz zdrowotność nasion. Wartość każdego z tych paramentów zależy od czynników środowiskowych i technologicznych. W Polsce znaczna część nasion wykorzystywany do siewu w uprawach zbożowych pochodzi z samorozmnożenia, a jego wartość siewna często odbiega od wymagań stawianych kwalifikowanemu materiałowi siewnemu. Natomiast jakość zastosowanego materiału siewnego ma wpływ na kształtowanie się plonów.
The basic parameters of the sowing value: purity, foreign seeds content, germination capacity and seed health. The value of each of these parameters depends on environmental and technological factors. In Poland, a significant part of seeds used for sowing in cereal crops comes from self-propagation, and its sowing value often differs from the requirements for certified seed. While the quality of the sowing material used has an impact on the yields.

Opis:: The aim of the research was to determine the factors defining the growth and development of Lolium perenne and Trifolium repens upon petroleum contamination. The top layer of clay soil contaminated with petroleum products resulting from an oil pipeline failure was collected for the tests. The control was the same type of uncontaminated soil with the addition of, under laboratory conditions, tissue paper. The research was conducted in two stages. The first concerned the germination process and seedlings parameters (Petri dishes). The germination energy (GE) and the germination capacity (GC) of seeds were determined. The seedling’s development was also evaluated based on ‘WinRhizo PRO 2009’ software. Then, in the second stage, pot tests were carried out, where the growth and development of species in the first year after sowing were temporarily measured. The parameters studied were the number, height, green and dry masses of the plants. A Gompertz regression model describing seed species germination and number species as time dependent dynamic was applied. The data were analysed statistically using variance analysis (ANOVA) and the PCA (principal component analysis) method. The results of our study indicated that admixture of petroleum into the soil does not seriously affect the development dynamics of Lolium perenne seedlings. The diesel oil contamination mostly affects the germination of the Trifolium repens by a statistically significant increase of the maximum value of germination and increasing the maximum growth rate.

Opis:: The date seeds (DS) biochar produced at 550°C was found to be appropriate for remediation of metal-contaminated water. This was evident in the data, which showed that applying the biochar to Raphanus sp. and Arabidopsis sp. reduced metal stress and toxicity. The LC50 of all tested metals solutions on seed germination was increased significantly (P<0.05) in Raphanus sp. by 10.4, 2.3, 5, 1.8, and 3 folds, respectively, for Cu, Zn, Cd, Pb, and metals combination, and by 5, 3.4, 6, 5.5, and 2.5 folds in Arabidopsis sp. For seedling growth, the DS biochar enhanced the LC50 significantly (P<0.05) of the same metals in Raphanus sp. by 9.6, 9.2, 13.8, 12.1, and 1.6 folds, and in Arabidopsis sp. by 7, 3, 2.3, 2.9, and 2.7 folds, respectively. The LC of all metals was increased by 1.5 to 8 times and 1.5 to 12 times, respectively, for the seed germination and seedling growth of Raphanus sp. and Arabidopsis sp. Both plants were able to grow shoots at higher metal concentrations when the DS biochar was employed, as compared to the case when no DS biochar was utilized. In terms of shoot length, similar results were achieved, with the DS biochar application significantly enhancing shoot length (P<0.05), as compared to the case when no biochar was applied. Despite the fact that Arabidopsis sp. was more sensitive to metals than Raphanus sp., both plants raised their RGR and TI and reduced their phytotoxicity values in all metals following the DS biochar application, and sprouted at higher metal concentrations than before. These findings introduce a successful eco-friendly adsorbent for metal removal from aquatic environments, paving the way for more investigations.

Opis:: The production of compost from biodegradable municipal waste is important not only for reducing the amount of landfilled waste. The compost produced with the right technology can replenish the missing organic matter in the soil and improve its properties. This paper deals with the evaluation of the phytotoxicity of composts from garden and kitchen biodegradable wastes. Their effect on plant germination and overall plant condition under laboratory conditions was investigated. The samples of compost from the industrial composting plant of the city of Nitra and compost from the electric composter GG02 were used for this test. The tested composts were mixed with the reference substrate in different concentrations and applied to two plant species – Lettuce (Lactuca sativa) and Barley (Hordeum vulgare). After 21 days, the number of germinated plants (i.e. germination rate), the length of the aerial part of the plants, the weight of fresh biomass and also its weight after drying were evaluated. The highest lettuce germination rate was obtained with 25% of the compost from the industrial composting plant. Barley achieved the best germination rate at up to 50% concentration of this compost. However, the highest biomass weight was obtained for the barley in the reference sample, i.e. without the addition of compost. In contrast, the application of compost from the industrial composting plant on lettuce, regardless of its concentration, had a clear stimulating effect, in all the parameters studied. The compost from the electric composter at concentrations of 25 and 50% had an inhibitory effect on all tested parameters of both plants.

Opis:: Regions with warm climate are poor in organic matter or have a deficit of soil. The purpose of the work was to select the optimal mix from biodegradable wastes such as cardboard (Cb), natural textiles (Tx) newspaper (Np), colored newspaper (Cp), and office paper (Op) for creating artificial soil by combining these materials with compost and sand. To select the optimum mix, 15 samples were taken (3 from each type of waste in the following proportions: 25%, 50% and 75% ). The optimum mix was analyzed for grass germination rate and root development. Tests were performed in the laboratory with conditions similar to those of regions with warm climate and soil deficiency in a specially designed testing spot (bioterm). The effects of particular mixes on plant germination rate and growth were measured. Out of all mixes, the textile compositions Tx50 and Tx25 supported best the plant propagation. During the whole experimental process, the grass showed various growth tendencies. The best results for grass height were observed for mixes with textiles and colored newspaper. Based on this data and subsequent laboratory research, the best substrate composition was selected. For the whole period of the tests, germination rate in the pot with the mix was higher than the germination rate in the control sample with compost. Considering the experimental conditions of this research, the tested substrates can be used to aid in plant propagation, especially in regions with warm climate and soil deficiencies, and for restoration of damaged land areas.

Opis:: Background. Soybean is a legume of substantial economic importance. The quality and quantity of soybean yield are influenced by various factors include pH soil. Many species of plants have strictly specified physiological requirements concerning the soil pH mainly in early phases of plant development, i.e. seed germination. Traditional methods used in germination data analysis include geramination energy and germination capacity. An alternative may be use tuse of growth models to describe germination process. Mathematical models give considerable information resulting in parameter estimates with relevant biological interpretations. Material and methods. Soybean seeds (cv. Abelina, Merlin and SG Anser) collected from cultivated plants grown in experimental fields in 2017 and 2018 were analysed. Field experiment was conducted in Łączka, eastern Poland (52°15′ N; 21°95′ E). After harvest, samples of seeds were collected and analysed in the laboratory, seed germination parameters were determined at different pH values of the water solution (pH = 5.0, 5.5, 6.0, 6.5, 7.0). The numbers of germinated seeds were recorded during the period of 14 days. Logistic function was used to analyse cumulative germination curves over time. The function parameters: value of the horizontal asymptote coefficients and rate of increase in germination rate, were calculated. Results. Generally, the seed germination was the better in 2017 than 2018. The numbers of seeds germinating in 2017 had the highest theoretical asymptotic value (parameter a) and low values of coefficients k (germination rate parameter) and b (shape parameter). Differences were found also between seeds germinated at different pH levels. The pH values of 6 and 6.5 provided were associated with the most rapid germination of all the test cultivars. Based on the logistic function, the highest number of germinated seeds was recorded between day 4 and 6 (germination rate ranging from 18 to 21% per 24 hours). Conclusion. Testing of germination of cultivars at different pH levels of the medium might be of help while identifying and selecting genotypes for particular locations.
Soja (Glycine max (L.) Merr.) jest jedną z najważniejszych roślin strączkowych na świecie. Na jakość i wielkość plonu soi mają wpływ różne czynniki, w tym kiełkowanie i pH gleby. Czas i sz ybkość kiełkowania to ważne parametry opisujące dynamikę tego procesu. W pracy przeanalizowano kiełkowanie nasion soi (odmiany: Abelina, Merlin i SG Anser) zebranych z roślin uprawianych na polach doświadczalnych w 2017 i 2018 roku. Na podstawie wyników doświadczenia laboratoryjnego oceniono dynamikę kiełkowania nasion w zależności od pH podłoża. Obliczono szybkość i tempo kiełkowania nasion oraz teoretyczną (asymptotyczną) wartość funkcji, wykorzystując w tym celu model logistyczny. Stwierdzono, że szybkość i tempo kiełkowania nasion pochodzących z doświadczenia z 2017 i 2018 roku były odmienne. Generalnie nasiona zebrane w 2017 roku charakteryzowały się większą szybkością i większym tempem kiełkowania niż nasiona zebrane w 2018 roku. Ponadto charakteryzowały się najwyższą teoretyczną wartością asymptotyczną (parametr a) oraz niskimi wartościami współczynników k i b. Odczyn podłoża o pH = 6 i pH = 6,5 warunkował najszybsze kiełkowanie nasion u wszystkich odmian.

Opis:: The fundamental aim of this study was to investigate the growth responses of selected Jordanian cultivated barley (Hordeum vulgare L.) genotypes to the salinity stress. Twenty-six landraces and two recent cultivars were subjected to four levels of salinity (0, 50, 100 and 200 mM NaCl). The salt stress was found to influence the majority of germination ability such as germination % which ranged from about 80% to 100% (One-way ANOVA; p ≤ 0.05). Moreover, germination was statistically affected in correspondence to exposure time to salinity and in relation to genotypic composition of studied barley (two-row vs. six-row accessions) (Two-Way ANOVA; p ≤ 0.05). Early seedling growth traits were also found to decline with increasing salinity stress. Moreover, according to the growth parameters genotypes, M’ 1595, M’ 1593, Ir 1558, Ir 1631, Ir 1639, Mf 1545, and Mf 1548 were found to have better performance than others. On the other hand, the genotypes M’ 1593, M’ 1594, M’ 1595, Ir 1558, Ra 1552, Ra 1611, Mf 1616, Mf 1617, and Ma 1592 were most affected genotypes by salinity. The results of this study lead to the conclusion that the response to the salinity stress is complex, yet the comprehensive results found in this study provide a foundation for deeper exploration of diversity as well as the gene–trait relationships and their utilization in future barley improvement.

Opis:: Background. Nanoparticles have been applied worldwide, posing substantial effects on the environment and its living organisms. Plants as sessile organisms are always exposed to considerable fluctuations of nanoparticles concentrations. Here, the effects of different concentrations of bulk and nanosized $Al_2O_3$ on seed germination and seedling growth of Cynara scolymus were investigated in a randomized completely design with four replications. Material and methods. The experimental treatments included four concentrations of bulk $Al_2O_3$ (10, 50, 100 and 500 ppm), four concentrations of nanosized $Al_2O_3$ (10, 50, 100 and 500 ppm), and control without any $Al_2O_3$. Results. The results indicated that among the Cynara scolymus germination indices, only mean germination time and weighted germination index was not affected by treatments. In addition, plumule length, radicle length, seedling fresh and dry weight were affected by bulk and nanosized $Al_2O_3$concentrations, significantly. Radicle length at 50 ppm concentration of nanosized $Al_2O_3$ was higher than those of the untreated control and bulk $Al_2O_3$Al 2O3 at 10, 100 and 500 ppm concentrations. It is concluded that treatment with bulk $Al_2O_3$ treatments have more inhibitory effects on germination indices of Cynara scolymus in comparison to nanosized $Al_2O_3$. Conclusion. Overall, we found through our study that bulk and nano sized $Al_2O_3$ in high concentrations have a negative impact on the seed germination and seedling growth of Cynara scolymus. We saw an overall significant reduction in plumule length, seedling dry biomass, and vigor index of Cynara scolymus seedlings after being exposed to different concentrations of bulk and nano sized $Al_2O_3$, but no significant change in the mean germination time, weighted germination index and radicle length of the seedlings. The two common possibilities are either the bulk and nano sized $Al_2O_3$ will adhere to the roots impeding any uptake of water and nutrients, or that the nanoparticles are up taken and translocated within the plant therefore causing toxicity internally.
Nanocząstki są stosowane na całym świecie, wywierając znaczny wpływ na środowisko i żywe organizmy. Rośliny jako organizmy ukorzenione są zawsze narażone na znaczne wahania stężeń nanocząstek. Zbadano wpływ różnych stężeń $Al_2O_3$ w masie i nanocząsteczkach na kiełkowanie nasion i wzrost siewek Cynara scolymus w całkowicie losowym projekcie z czterema powtórzeniami. Zabiegi doświadczalne obejmowały cztery stężenia $Al_2O_3$ w masie (10, 50, 100 i 500 ppm), cztery stężenia $Al_2O_3$ w postaci nanocząstek (10, 50, 100 i 500 ppm) oraz kontrolę (bez $Al_2O_3$). Wyniki wskazują, że spośród wskaźników kiełkowania Cynara scolymus zabiegi nie miały wpływu na średni czas kiełkowania i ważony wskaźnik kiełkowania. Na długość pędu embrionalnego, długość korzonków, świeżą i suchą masę siewek istotnie wpływały stężenia $Al_2O_3$ w masie i nanoskali. Długość rodnika przy stężeniu 50 ppm $Al_2O_3$ w postaci nanocząstek była wyższa w porównaniu z kontrolą i masowym $Al_2O_3$ przy stężeniach 10, 100 i 500 ppm. Stwierdzono, że traktowanie dużą ilością $Al_2O_3$ ma bardziej hamujący wpływ na wskaźniki kiełkowania Cynara scolymus niż stosowanie $Al_2O_3$ w postaci nanocząstek. W badaniach określono, że Al2O 3 w dużych ilościach i w wysokich stężeniach nanocząsteczek ma negatywny wpływ na kiełkowanie nasion i wzrost siewek Cynara scolymus. Zaobserwowano znaczne zmniejszenie długości pędu embrionalnego, suchej masy sadzonek i wskaźnika wigoru siewek Cynara scolymus po ekspozycji na różne stężenia $Al_2O_3$ w rozmiarze masowym i nano, ale bez znaczących zmian w średnim czasie kiełkowania, ważonym wskaźniku kiełkowania i długości korzonków siewek. Wynika to albo z przywierania $Al_2O_3$ do korzeni w rozmiarze masowym i nanometrowym, utrudniając wchłanianie wody i składników odżywczych, albo nanocząsteczki są pobierane i przemieszczane w obrębie rośliny, powodując w ten sposób toksyczność wewnętrzną.

Opis:: The study explored propagation techniques of Entada rheedii Spreng., a threatened medicinal climber species with extremely hard seed coat. Propagation trials included both pre-sowing treatments of seeds for germination and clonal propagation by stem cutting. Pre-sowing treatments included (a) soaking of both cut (notched) and uncut (intact) seeds in water for 0 h, 24 h, 48 h, and 72 h and (b) immersion of intact seeds in 5% acetone solution for 5 min, 10 min, and 20 min before sowing in germination media in polybags. On the other hand, stem cutting involved treating the summer or autumn cuttings with 0%, 0.4%, and 0.8% IBA solution before rooting in non-mist propagator. Notched seeds soaked in water for 48 h showed the fastest seed germination with the highest germination percentages (73.3) and better seedling growth in terms of plant height, collar diameter, leaf number and total dry mass followed by notched seeds soaked in water for 72 h. The slowest germination and the lowest germination percentage (3.3), as well as the poorest growth performance was for intact seeds without any treatment. The highest rooting percent- age with maximum number of roots (36.6) was obtained from the summer cuttings treated with 0.4% IBA solution followed by autumn cuttings with 0.8% IBA and the lowest (43.3% and 8.3 roots) was for summer cuttings in control. The factors also dictated the survival and growth performance of rooted cuttings in the nursery conditions. The outcomes of these trials i.e., notched seeds soaking in water for 48 h will help to enhance the propagation of this valuable medicinal plant species.
