Opis:
In the year 1997 distinct injures on winter wheat cv. Kobra were stated strongly resembling symptoms of infection caused by Fusarium. On prematurely ripening plants a partial or total yellowing of ears was observed, and lower parts of internodes showed brown discoloration. It was stated after careful examination that culms and ears were infested with numerous mites, Tyrophagus longior (Gerv.), not by species of Fusarium. The mites probably contributed to decrease in grain yield. Kernels were small and underdeveloped which influenced the decrease of quality of seeding material.
Na początku lipca 1997 roku otrzymaliśmy próbkę roślin pszenicy z podejrzeniem o choroby grzybowe, powodowane przez rodzaj Fusariurn. Po dokładnym przebadaniu stwierdzono brak grzybów z rodzaju Fusariurn, natomiast stwierdzono roztocze z rodzaju Tyrophagus, które wystąpiły w znacznej liczbie, porażając pędy, pochwy liściowe oraz kłosy. Najczęściej spotykano Tyrophagus longior (Gerv.), który przegryzał źdźbło w części nadkolankowej, gdyż miał tam zapewnioną wilgotność i temperaturę. Z kłosów silnie porażonych zebrano mniejszy plon. Ziarniaki były drobniejsze, co miało znaczny wpływ na jakość materiału siewnego, a w dalszej kolejności obniży plon w roku następnym.

Opis:
On the basis of sweep netting samples and young plant and spike samples, the species composition and the incidence of thrips (Thysanoptera) on rye and winter wheat in different regions of Poland have been determined. A list of 49 Thysanoptera species found on these cereal crops and an overview of 11 species referred to "cereal thrips" have been given. The undertaken studies have showed that Haplothrips aculeatus Fab. was dominant on both rye and winter wheat crops.
W latach 1981, 1983-1991 przeprowadzono badania nad występowaniem przylżeńców (Thysanoptera) na uprawach żyta i pszenicy ozimej w różnych rejonach Polski. Na podstawie 280 prób z żyta oraz 310 prób z pszenicy ozimej, zebranych w 36 powiatach należących do 15 województw, ustalono skład gatunkowy wciornastków znalezionych na tych zbożach. W sumie zgromadzono 40 161 osobników dorosłych i larw Thysanoptera należących do 49 gatunków. Wśród nich wyodrębniono grupę „wciornastków zbożowych” obejmującą 11 gatunków: Anaphothrips obscurus (Müller), Aptinothrips rufus (Haliday), Aptinothrips stylifer Trybom, Chirothrips manicatus Haliday, Frankliniella tenuicornis (Uzel), Haplothrips aculeatus (Fabricius), Haplothrips tritici Kurdjumov, Limothrips cerealium Haliday, Limothrips denticornis (Haliday), Stenothrips graminum Uzel i Thrips angusticeps Uzel. Stanowiły one ponad 95% wszystkich zgromadzonych osobników Thysanoptera. Na życie dominowały na terenie Polski dwa gatunki, a mianowicie: Haplothrips aculeatus Fab. (65,2% wszystkich znalezionych na tym zbożu „wciornastków zbożowych”) oraz Limothrips denticornis Hal., stanowiący 27,6% wszystkich osobników. Z pozostałych gatunków „wciornastków zbożowych” liczniej na życie występował Chirothrips manicatus Hal. (2,8% osobników). Na pszenicy ozimej najliczniejszym gatunkiem był Haplothrips aculeatus Fab., który stanowił 48% wszystkich „wciornastków zbożowych”. Na terenie południowo-wschodniej Polski dominował Haplothrips tritici Kurdj., a procentowy udział H. aculeatus spadł do 29%. Wśród innych gatunków zbożowych znalezionych na pszenicy najliczniej wystąpiły: Limothrips denticornis (11,4%) i Frankliniella tenuicornis (5,4%). Pozostałe gatunki „wciornastków zbożowych” wystąpiły na życie i pszenicy ozimej nielicznie, że można je potraktować jako element przypadkowy na tych uprawach.

The paper presents results of a plot experiment with 20 varieties of winter wheat artificially infested with Tilletia caries (DC.) Tul. Significant differences in susceptibility of varieties to the pathogen were found. Percentage of diseased ears ranged from 0.75 to 20.00, the least infected were varieties Begra, Elena, Juma and Gama. Percentage of grain yield decrease, as compared to non-infected control, was the highest for varieties Maltanka, Kobra, Wilga, Zorza and Kamila. In most cases grain yield decrease of varieties was related to the percentage of diseased ears found on experimental plots with these varieties.
W pracy przedstawiono wyniki doświadczenia ścisłego, w którym przedmiotem badań było 20 odmian pszenicy ozimej sztucznie zakażonych teliosporami Tilletia caries. Stwierdzono występowanie różnic w podatności odmian na patogena. Procent porażonych kłosów w poszczególnych odmianach wahał się od 0,75% do 20,0%. Do najsłabiej porażonych należały odmiany: Berga, Elena, Juma i Gama. Obniżka plonu w porównaniu do nie zakażonej kontroli była największa w przypadku odmian: Maltanka, Kobra, Wilga, Zorza i Kamila. Dla większości odmian wielkość strat w plonie ziarna zależała od liczby porażonych kłosów.

Opis:
Growth regulators, or retardants, play a significant rolein the crop protection system, minimizing the risk of lodging. Thephenomenon of lodging contributes to qualitative losses and deteriorationof grain quality. In this paper, the effect of retardanttype, its rate and date of application, on selected quality featuresof winter wheat grain was evaluated.The study was carried out at the IUNG Experimental Stationin Osiny with winter wheat cultivar 'Roma', grown after rootcrops. The experiment was conducted on the soil of the good ryecomplex. The three-year study was conducted using the methodof randomized split-plot with a control treatment, in four replications.The formulas of retardants (Cycocel 460 SL - chlormequatand Terpal C 460 SL - chlormequat + ethephon), application date(full tillering and first and second node stage) and application rate(maximum and minimum recommended by the Institute of PlantProtection) were the test factors.The reaction of wheat to the examined factors depended onthe type, rate and timing of retardant application. Statisticallysignificant differences in grain glassiness, gluten quality and theactivity of amylolytic enzymes, were found vs. the values of thecontrol sample. The application of retardants had no statisticallysignificant effect on grain bulk density, ash content and total proteinand gluten content.

In the years 1995-1997, studies were carried out on the occurrence of aphids and ladybirds on winter wheat in the south-eastern Poland. Depending on the atmospheric conditions the first aphids on wheat plantations were found from decade II of May. The peak of their mass occurrence was recorded in decads II and III of June. The first overwintering beetles ladybirds began their flight over the plantations from decade III of April till decade II of May. The peak of a mass occurrence of these beetles was noted in decades II and III of May. In all the localities and years of the studies the peak of a mass occurrence of beetles of ladybirds always preceded the mass occurrence of aphids on winter wheat.

Opis:
The research on the influence of pollution emitted by the WBM-30 bituminous mass factories on the winter wheat-crop was carried out in 1981. The factory was situated in the agricultural area far from the farm buildings in the village of Trzebownisko. The experimental area was divided into four zones (three zones of pollution and one control zone). The wheat ear samples were collected during full grain ripeness per 100 ears from different plantations in three repetitions in each zone. They showed that all examined features, such as, e.g. the average ear length and 1000 grain mass were substantially different between the 1st pollution zone and control zone.
Wytwórnie mas bitumicznych zlokalizowane są na obszarach rolniczych z dala od zabudowań wiejskich. Ich wydajność masy bitumicznej wynosi od 30 do 100 ton w ciągu jednej godziny. Badania nad wpływem emitowanych zanieczyszczeń na plonowanie pszenicy ozimej przeprowadzono w 1981 roku. Zakład o wydajności około 30 ton zlokalizowany był w pobliżu miejscowości Trzebownisko. Teren badań podzielono na 4 obiekty, 3 obiekty w strefie zanieczyszczonej oraz obiekt kontrolny. Próby kłosów pszenicy ozimej pobierano po 100 kłosów w trzech powtórzeniach w każdym obiekcie doświadczalnym, w czasie pełnej dojrzałości ziarna. Otrzymane wyniki badań w zakresie plonowania tego zboża, opracowano statystycznie. Wszystkie badane cechy różniły się istotnie pomiędzy obiektem kontrolnym a I strefą zanieczyszczeń.

Opis:
.Measurements of single-kernel mass and volume made on healthy (control) and scab-damaged samples of grain of three winter wheat varieties never resulted in lower values of mean single-kernel density for scab-damaged grain. This finding, contrary to common opinion, can be explained as being a result of the comparable magnitude of relative decrease (due to infestation) of two features (mass and volume) that define single-kernel density. The discrepancy between results presented in this paper (kernel volume was determined with an air pycnometer) and the results in some other reports (liquid pycnometers used) can result from the different methods applied for kernel volume measurements: when a liquid medium is used the surface tension effect tends to overestimate the volume, especially for scabby kernels that are known to be shrivelled ie possessing voids and pores at the surface that the liquid cannot penetrate. As a consequence kernel density of scabby kernels can be significantly underestimated.

Opis:
Plants were regenerated from immature embryo cultures of 35 winter wheat genotypes. General responses of regenerated plants were investigated and a total of 7142 R₂ spike lines from 1593 R₁ plants were assessed in the field for somaclonal variants in 1985/86, 1986/87 and 1987/88. Selected variants were studied for their possible genetic inheritance. From regenerated plantlets, 81% survived and 63% produced fertile plants. Forms with reduced plant height, length of spike and other morphological abnormalities were found in this progeny. Populations of R₁ plants were highly variable due mainly to the physiological disturbances resulting from the in vitro process. Overall somaclonal variation frequencies were 14.2% per plant basis and 5.3% per R₂ spike basis. The variants were similar in the three different R₂ generations with predominant variants being negative in plant height, maturity, awns, spike type and plant type. Both uniform R₂ variant families and spike lines were found in addition to the segregating variants which constituted the majority. On average, in a variant family or line, 18% and 14% of their component lines and plants were variants, respectively. Inheritability was demonstrated for the uniform variant families and spike lines as well as segregated variants. Of those 134 selections, about 70% were classified as inheritable. Both recessive and dominant gene mutations at one, two or three loci were evident in some variants as suggested by the segregating data.

Soil thermal properties can influence several soil processes important for crop productivity. This study was conducted to evaluate the influence of cover crops on selected soil physical and thermal properties. The field site was set up using a randomized complete block design with two levels of cover crops (cover crops versus no cover crops). The soil thermal properties measured included thermal conductivity, volumetric heat capacity, and thermal diffusivity. The physical properties of the soil studied included bulk density, volumetric water content, total pore spaces, water-filled pore spaces, air-filled pore spaces, gas diffusion coefficient, and soil pore tortuosity factor. Soil organic carbon was also measured. The results showed that soil organic carbon was 26% higher under cover crops management compared to no cover crops management. Thermal conductivity and thermal diffusivity were positively correlated with soil bulk density and these properties (soil thermal conductivity and soil thermal diffusivity) were higher under no cover crops management compared with cover crops management probably due to the proximity between soil particles. The volumetric heat capacity was positively correlated with soil organic carbon, with soil organic carbon being higher under cover crops management compared with no cover crops management. Results from the current study show that cover crops can improve soil physical and thermal properties which may benefit crop productivity as corroborated via laboratory measurements.

Opis:
A new trend in plant protection consists in the integration of biological and chemical control treatments. Unfortunately, the biological control agents for winter wheat are still in short supply. Bacteria of the genus Sphingomonas have a unique ability to produce prolyl endopeptidases. Those enzymes are capable of hydrolyzing the peptide PQPQLPYPQPQLP. During the growing season, the bacteria may be used to protect winter wheat against infections caused by fungi of the genera Fusarium. The objective of this study was to evaluate the effectiveness of bacterial isolates in protecting field- -grown winter wheat plants against spike infections and to assess the effect of bacteria on the chemical composition and microbiological purity of winter wheat grain. The effects of bacteria of the genus Sphingomonas as biological control agents against Fusarium head blight (FHB) of winter wheat were evaluated in a three-year field experiment. For comparative purposes, the fungicides propiconazole at the elongation stage (BBCH 31) and fluoxastrobin + prothiconazole at the heading stage (BBCH 55) were applied. In 2010 and 2011, the application of cell suspensions of bacteria alleviated the symptoms of disease by 27.3% and 75.8%, respectively in comparison with control. Wheat grain yield was higher in plots subjected to the biological and chemical treatment (by an average of 9.5 and 13.6%, respectively). For the first time, we observed that biological control modified the chemical characteristics of wheat grain. In control grain, the content of gluten proteins was 7.9% higher than in grain treated with the biocontrol agent. In wheat grain treated with the biocontrol agent, the highest decrease was observed in the concentrations of alpha/beta-gliadins (10.59%), but grain quality was most affected by an estimated 8% decrease in the content of HMW glutenins. Biological treatment inhibited the growth pathogens of F. culmorum, F. poae, F. sporotrichiodes and F. avenaceum. A cell suspension of bacteria did not inhibit the growth of yeasts and epiphytic bacteria of the genus Azotobacter on grains.

Opis:
Fusarium mycotoxins are secondary metabolites, bio-synthesized by filamentous fungi of the genus Fusarium, which, due to their diverse toxicity and difficulty in their removal from food and animal feeds, are the subject of research by scientists around the world. The most important mycotoxins found in wheat are: deoxynivalenol (DON), zearalenone (ZEN), and the T-2 and HT-2 toxins. Bearing consumer safety in mind, the levels of these substances in grain, food and animal feeds are regulated by law. In order to meet the health safety requirements imposed on grain, it is important to minimise the risk of fungal infection at individ-ual production stages. Weather conditions are the most important factor influencing the development of fungi and the accumula-tion of mycotoxins in grain. High temperature, combined with rainfall, are factors favouring the spread of fungal spores. Apart from weather conditions, individual elements of the production technology, such as appropriate variety selection, soil cultivation method, preceding crop, use of fungicides, and fertilization may reduce the quantity of mycotoxins in grain. In the conditions of the emerging climatic changes, favouring the development of fun-gal diseases, creating wheat varieties resistant to fungal diseases is a considerable challenge. Acquiring more in-depth knowledge on the relationship between the phenotypic features of a wheat variety and mycotoxin content would be helpful. This work is of review character and aims to indicate the basic factors influenc-ing the production of fusarium mycotoxins in winter wheat grain. The focus was placed on factors independent of human activity (weather conditions) and on individual elements of cultivation technology.

Opis:
New solutions in plant protection applications are still highly desirable. Aiming at higher efficiency, environmental safety and profitability of production which, in addition to reducing the costs of the application of plant protection products, limits the destruction of soil structure combined use of agrochemicals seems to be one of the most important method in modern agriculture. In 2016 and 2017, the Plant Protection Institute – National Research Institute in Poznań, Poland, conducted field experiments on the possibility of combining two popular herbicides used to control monocotyledonous weeds: pinoxaden and fenoxaprop-P-ethyl, with a two-component plant growth and development regulator (mepiquat chloride and prohexadione calcium) on KWS Ozon winter wheat. The tested substances were applied at the BBCH 24 stage of winter wheat – herbicide only, and at the BBCH 31 stage – a mix of herbicides with a plant growth and development regulator. Regardless of the method of application of pinoxaden (herbicide only or mixed), high effectiveness of Apera spica-venti control was obtained in both years of the study. The mix of pinoxaden with mepiquat chloride and prohexadione calcium reduced the wheat crop height to a similar extent as separate application of the substances. The combined application of fenoxaprop-P-ethyl with mepiquat chloride improved the effectiveness of wheat crop height control. The method of application of the substances had no significant effect on winter wheat yield. Grain yields harvested from plots treated with the above substances were significantly higher than control only in the case of high weed infestation of winter wheat. The technological value of wheat grain depended on the year of study, while the method of application did not have a significant impact on the evaluated parameters.

Opis:
On wheat seeds harvested in Upper Silesia (south-western Poland) a large number of species of Fusarium were recorded. Fusarium avenaceum and F. culmorum were most commonly isolated. Flooding of fields for 1-7 days caused the increase of pathogenic Fusarium spp. in seed samples, especially F. culmorum. The infection of seeds caused a rapid decrease of their viability, and negatively affected health status of emerging seedlings in field conditions, in spite of performed chemical treatment.
W artykule przedstawiono wyniki analizy mikologicznej ziarna pszenicy ozimej z terenów objętych powodzią na Górnym Śląsku (południowo-zachodnia Polska). Zalanie upraw pszenicy wodą przez okres 1-7 dni spowodowało wzrost udziału w mikoflorze ogólnej ziarna patogenicznych gatunków Fusarium, głównie F. culmorum. Procentowy udział gatunku F. avenaceum w grupie patogenicznych gatunków z tego rodzaju był wyższy na ziarnie z terenów niezalanych wodą. Stwierdzono negatywny wpływ wysokiego zasiedlenia ziarna przez gatunki Fusarium na jego zdrowotność, co wyrażało się znacznym obniżeniem siły kiełkowania w czasie jego przechowywania oraz obniżeniem zdrowotności siewek.

Opis:
Eyespot can reduce yields, even up to 50%. There are four genetically characterized resistances in wheat varieties, controlled by: (1) the Pch1 gene, transferred from Aegilops ventricosa; (2) the Pch2 gene, originating from wheat variety Capelle Desprez; (3) the Pch3 gene, originating from Dasypyrum villosum; and (4) the Q.Pch.jic-5A gene, a quantitative trait locus (QTL) located on chromosome 5A of Capelle Desprez. However, those loci have drawbacks, such as linkage of Pch1 with deleterious traits and limited effectiveness of Pch2 against the disease. Here we present an initial study which aims to characterize wheat pre-registration breeding lines carrying 12 eyespot resistance genes, consider their resistance expression in inoculation tests and the influence of resistance genotypes on the yield. We selected four groups of breeding lines, carrying: (1) the Pch1 gene alone: one line; (2) the Pch2 gene alone: four lines; (3) the Q.Pch.jic-5A gene alone: one line; and (4) Pch1 + Q.Pch.jic-5A: three lines. For the first time, the effect of the combination of Pch1 and Q.Pch.jic-5A genes was compared with resistance conferred by Pch1 or Q.Pch.jic-5A alone. We found significant differences between infection scores evaluated in resistant lines carrying Pch1 and Q.Pch.jic-5A alone, while no differences in terms of the level of resistance expression were detected between Pch1 alone and Pch1 + Q.Pch.jic-5A, and between wheat lines carrying Pch1 and Pch2 alone. Moreover, we demonstrated that the Pch1 gene, together with an Ae. ventricosa segment, caused statistically significant yield losses, both as a single eyespot resistance source or in a combination with Q.Pch.jic-5A. Yield scores showed that wheat lines with Q.Pch.jic-5A had the highest yields, similar to the yielding potential of Pch2-bearing lines and control varieties.

Opis:
Ears of winter wheat cultivars (Bogatka and Legenda) grown under conventional and ecological (organic) farming systems, were sampled at different developmental stages and examined for their colonization by filamentous fungi, including Fusarium spp. Ears samples were shaken in sterile water containing 0.01% of Tween 80 and appropriate 10-fold dilutions of the initial suspension were inoculated onto agar medium containing antibiotics to inhibit bacterial contaminants. After 6-7 days of incubation at 28o C fungal colonies were counted and after further 4 days fragments of colonies were transferred onto other media for identification. On ears at flowering no Fusarium species were found in 2008 with dry and hot July, but in 2009 with more frequent rainfalls in July Fusarium poae, F. tricinctum and F. avenaceum were detected on winter wheat ears at the flowering stage. At the hard kernel stage the following species were isolated from winter wheat ears: F. poae and F. sporotrichioides in 2008 (17 and 18 isolates respectively) and F. avenacum, F. crookwellense, F. poae, F. sporotrichioides and F. tricinctum in 2009 (2, 18, 39, 2 and 17 isolates respectively, and 9 unidentified Fusarium). In 2008 more Fusarium spp. were found on winter wheat ears grown under the conventional system than under the ecological (organic) system. In the ecological system wheat stands are thinner but taller (due to the lack of any mineral fertilizers and plant growth regulators) and in consequence winter wheat ears in this system may keep moisture shorter than those in the conventional system. It seems that this difference may be the most important factor influencing colonization of winter wheat ears by Fusarium spp. and other fungi under the compared farming systems.
