Opis:: Nutrient deficiency (ND) stands as a prominent environmental factor that significantly impacts global plant growth and productivity. While numerous methods have been employed for detecting nutrient deficiencies in plants, many of them are invasive, time-consuming, and costly. In contrast, chlorophyll fluorescence (ChlF) signals have emerged as a non-destructive tool for the identification of specific nutrient deficiencies, such as nitrogen (N), phosphorus (P), and potassium (K), across various plant species. In this pioneering study, ChlF measurements were employed for the first time to detect a combination of nutrient deficiencies, including deficiencies in nitrogen and phosphorus (-NP), nitrogen and potassium (-NK), potassium and phosphorus (-KP), and a complete NPK deficiency (-NPK). The experiment was conducted using wheat (Triticum aestivum) and maize (Zea mays) plants, which were grown under controlled laboratory conditions. An optimal hydroponic system was established to facilitate eight experimental conditions, namely: control, -N, -P, -K, -NP, -NK, -KP, and -NPK. Measurements were systematically collected at two-day intervals over a span of 24 days. Our findings demonstrate that chlorophyll fluorescence signals can enable the differentiation of various nutrient deficiencies even prior to the onset of observable symptoms. Furthermore, the examination of chlorophyll fluorescence parameters enables us not only to identify a singular macronutrient deficiency but also to detect multiple macronutrient deficiencies concurrently in a plant.

Opis:: In 2013–2016 the possibility of combined application of herbicides with retardants in winter wheat was investigated in Institute of Soil Science and Plant Cultivation in Wrocław. Two retardants (1. chloromequate chloride, 2. trinexapac-ethyl) were used in tank mixture with fluroxypyr and florasulam + amino- pyralide. The mixtures were applied on two dates: 1. at the end of tillering, 2. at the stage of 1–2 nodes (florasulam + amino- pyralide) or at the stage of flag leaf (fluroxypyr). Efficacy of weed control was affected only by date of treatment. Irrespective of which herbicide-retardant combination was used, the weed sup- pression was the lowest on plots treated with the mixtures at a later growth stage. It was reflected in the size of grain yield re- ceived from these plots, that was comparable to untreated control. Application of the mixture of fluroxypyr with trinexapac-ethyl in winter wheat tillering and flag leaf growth stages contributed to seed uniformity decrease.

Opis:: Researchers from the Siedlce University of Natural Sciences and Humanities carried out an investigation in 2017-2019, on a family farm located in Krzymosze (52°03′27″N, 22°33′74″E) near Siedlce, Poland, aiming at determining the effect of biofertilisers and nitrogen fertiliser regime on the protein content as well as macroelements in the grain of spring wheat produced in a sustainable agriculture system. The following two factors were examined: (I) biological preparations: control where no biological preparations were applied, Azotobacter vinelandii, L- proline, Azotobacter vinelandii + L-α proline; (II) mineral nitrogen regime: unamended control, 60 kg N ha-1, 90 kg N ha-1, 120 kg N ha-1. Spring wheat grain was sampled to determine the total protein content and macroelements (P, K, Ca and Mg). The results demonstrated that the biological nitrogen preparations Azotobacter vinelandii + L- proline applied simultaneously with 90 kg N ha-1 contributed to the production of spring wheat grain with the highest concentration of protein and phosphorus, potassium, calcium and magnesium, all being very important in human nutrition. The use of the biological preparation Azotobacter vinelandii and L- proline biostimulator with a fertilisation dose of mineral nitrogen of 90 kg N ha-1 ensures favorable chemical composition of spring wheat grain. Moreover, such form of fertilisation protects the soil environment, an issue of growing importance in modern agriculture. It should be recommended to apply bioproducts in combination with lower nitrogen mineral fertilisation doses in spring wheat cultivation.

Opis:: Using in vitro androgenesis serves as a unique opportunity to produce doubled haploid (DH) plants in many species. More benefits of this biological phenomenon have kept these methods in the focus of fundamental research and crop breeding for decades. In common wheat (Triticum aestivum L.), in vitro anther culture is one of the most frequently applied DH plant production methods. The efficiency of in vitro wheat anther culture is influenced by many factors, such as the genotype, growing conditions, collection time, pre-treatments, and compositions of media and culture conditions. According to some critical review, the genotype dependency, low efficiency and albinism are mentioned as limitations of application of the anther culture method. However, some research groups have made significant efforts to diminish the effects of these bottlenecks. Due to the improvements, a well-established in vitro anther culture method can be an efficient tool in modern wheat breeding programs.

Opis:: Accumulation of LaCl3 , a well-known Ca 2+ -channel blocker, can inhibit plant growth. However, the current understanding of its effects on gene expression is limited. In this paper, different concentrations of LaCl 3 (0, 0.5, 1.0, 1.5, 2.0 mM) were used to treat germinated wheat (Triticum aestivum L.) seeds for 24 h. The degree of root growth inhibition gradually increased with increasing LaCl 3 concentration. qRT-PCR analysis revealed that the expression of several key genes related to the cell cycle process, such as pcna, mcm2, rdr and cyclin B, were significantly down-regulated. Further analysis of genomic DNA instability using Random Amplified Polymorphic DNA (RAPD) and methylation levels by Coupled Restriction Enzyme Digestion-Random Amplification (CRED-RA) analysis indicated a significant increase in genomic DNA polymorphisms and methylation levels. The results of this study verified that the reasons why LaCl3 treatment can inhibit the growth of wheat roots are as follows: interference in the normal progression of the cell cycle, induction of genomic DNA instability and increase in DNA methylation levels.

Opis:: Celem trzyletniego doświadczenia polowego była ocena reakcji pszenicy ozimej, odmiany RGT Kilimanjaro na zróżnicowane nawożenie dolistne. Doświadczenie założono w układzie losowanych bloków na polach Podkarpackiego Ośrodka Doradztwa Rolniczego w Boguchwale. Badanym czynnikiem były zróżnicowane warianty nawożenia dolistnego: (B) – dwukrotny oprysk YaraVita Zboże oraz (C) – dwukrotny oprysk YaraVita Zboże, jednokrotny YaraVita Kombiphos i jednokrotny YaraVita Thiotrac, które porównano do kontroli (A). Wykazano, że zmienne warunki pogodowe w latach badań wpłynęły modyfikująco na uzyskane plony. W 2017 r. zebrano ponad 9 t⸱ha-1 ziarna, natomiast w latach 2018 i 2019 odpowiednio o 2,0 i 0,92 t⸱ha-1 mniej. Po zastosowaniu nawożenia dolistnego w wariancie C i B uzyskano istotnie wyższe plony w porównaniu do kontroli, odpowiednio o 0,72 t⸱ha-1 i 0,44 t⸱ha-1. Czterokrotne nawożenie dolistne (wariant C) wpłynęło na istotny wzrost MTZ oraz indeksów zieloności liści (SPAD) i powierzchni liści (LAI) w porównaniu do kontroli. W przypadku przewodności szparkowej liści (Gs) dowiedziono, że zastosowane nawożenie w wariancie C skutkowało zmniejszeniem odczytów w odniesieniu do kontroli. Użyte nawozy dolistne w wariancie C wpłynęły także na istotny wzrost zawartości w ziarnie białka ogólnego a spadek włókna w odniesieniu do kontroli. W przypadku wariantu B uzyskane różnice były nieistotne. W uprawie pszenicy ozimej należy zatem zalecać intensywniejszy wariant nawożenia dolistnego.
The aim of the three-year field experiment was to evaluate the reaction of winter wheat, RGT Kilimanjaro cultivar to different foliar fertilization. The experiment was set up in a randomized blocks in the fields of the Podkarpackie Agricultural Advisory Center in Boguchwała. The tested factor consisted of various variants of foliar fertilization: B – two-time spraying of YaraVita Grain and C – two-time spraying of YaraVita Grain, one-time YaraVita Kombiphos and one-time YaraVita Thiotrac, which were compared to the control (A). It was shown that the variable weather conditions in the years of the research had a modifying effect on the yields obtained. In 2017, more than 9 t⸱ha-1 grain was harvested, while in 2018 and 2019, by 2.0 and 0.92 t⸱ha-1 less, respectively. After applying foliar fertilization in variants C and B, the yields were significantly higher compared to the control, by 0.72 t⸱ha-1 and 0.44 t⸱ha-1, respectively. Four-fold foliar fertilization (variant C) significantly increased WTG and indices of Soil Plant Analysis System (SPAD) and leaf area index (LAI) compared to the control. In the case of the stomatal conductivity of leaves (Gs), it was proved that the applied fertilization in variant C resulted in a decrease in readings in relation to the control. The foliar fertilizers used in variant C significantly increased the content of total protein in the grain and the decrease in fiber compared to the control. In the case of variant B, the obtained differences were insignificant. Therefore, in the cultivation of winter wheat, a more intensive variant of foliar fertilization should be recommended.

Opis:: Bread wheat is a major food crop on a global scale. Stripe rust, caused by Puccinia strii- formis f. sp. tritici, has become one of the largest biotic stresses and limitations for wheat production in the 21st century. Post 2000 races of the pathogen are more virulent and able to overcome the defense of previously resistant cultivars. Despite the availability of effective fungicides, genetic resistance is the most economical, effective, and environmen- tally friendly way to control the disease. There are two major types of resistance to stripe rust: all-stage seedling resistance (ASR) and adult-plant resistance (APR). Although both resistance types have negative and positive attributes, ASR generally is race-specific and frequently is defeated by new races, while APR has been shown to be race non-specific and durable over time. Finding genes with high levels of APR has been a major goal for wheat improvement over the past few decades. Recent advancements in molecular mapping and sequencing technologies provide a valuable framework for the discovery and validation of new sources of resistance. Here we report the discovery of a precise molecular marker for a highly durable type of APR – high-temperature adult-plant (HTAP) resistance locus in the wheat cultivar Louise. Using a Louise × Penawawa mapping population, coupled with data from survey sequences of the wheat genome, linkage mapping, and synteny analysis techniques, we developed an amplified polymorphic sequence (CAPS) marker LPHTAP2B on the short arm of wheat chromosome 2B, which cosegregates with the resistant pheno- type. LPHTAP2B accounted for 62 and 58% of phenotypic variance of disease severity and infection type data, respectively. Although cloning of the LPHTAP2B region is needed to further understand its role in durable resistance, this marker will greatly facilitate incorpo- ration of the HTAP gene into new wheat cultivars with durable resistance to stripe rust.

Opis:: Seed is the most crucial and prime input in agriculture, and the seed must be of high quality. Seed priming is one of the reliable and cost-effective strategies to enhance seed germination and seedling establishment in crops. This study was conducted to determine the effects of seed priming with Mg(NO3)2 (S1) and ZnSO4 (S2) in two wheat (Triticum aestivum L.) varieties (HUW-468 and HUW-510) on germination and seedling growth. Varied levels of Mg(NO3)2 and ZnSO4 from C0 to C11 were used for the present study and number of seed germinated, seedling establishment and biochemical parameters were recorded. From the study of germination %, mean germination time (MGT), mean germination rate (MGR), coefficient of velocity of germination (CVG), germination rate index (GRI) (% / day), germination index (GI), seedling vigor (SV), shoot, root and seedling length, α-amylase activity, soluble and insoluble sugar content and protein content, it was revealed that 7.5 mM of Mg(NO3)2 and 0.05 mM of ZnSO4 were the best treatments in improving seedling establishment, performance and biochemical status of wheat seed. Further, this analysis also reveals a strong correlation between the seedling establishment and the activity of -amylase and protein content.

Opis:: Łamliwość źdźbła to jedna z ważniejszych chorób pszenicy uprawnej (Triticum aestivum L.) powodowana przez dwa grzyby patogeniczne Oculimacula yallundae i Oculimacula acuformis. Istnieje kilka źródeł odporności na ten patogen, lecz jak dotąd tylko dwa geny Pch1 i Pch2 zostały przniesione do pszenicy uprawnej i warunkują odporność. Wybranie najkorzystniejszych markerów molekularnych dla określenia obecności genów odporności na łamliwość źdźbła u pszenicy może poprawić skuteczność i dokładność przy wyborze genotypów odpornych na tę chorobę. Celem pracy było określenie efektywności markerów molekularnych i markera izoenzymatycznego dla genów Pch1 i Pch2 oraz wytypowanie genotypów pszenicy ozimej o podwyższonej odporności w odniesieniu do porażenia roślin w testach inokulacyjnych przeprowadzonych w fazie siewki oraz rośliny dojrzałej. Materiał badawczy stanowiło 159 linii hodowlanych pszenicy ozimej oraz pięć odmian kontrolnych: Artist, Kilimanjaro, Kometa, Patras i Rendezvous. Do identyfikacji genów odporności wykorzystano pięć markerów, trzy do identyfikacji genu Pch1 (EpD1b, XustSSR2001-7DL, Xorw1) oraz dwa dla genu Pch2 (Xcfa2040, Xwmc525). Biorąc pod uwagę analizę molekularną genów, wyniki inokulacji siewek oraz wyniki porażenia źdźbeł dojrzałych roślin, stwierdzono brak objawów porażenia źdźbeł u linii/odmian pszenicy ozimej, u których zidentyfikowano oba geny Pch1 i Pch2. Stwierdzono u nich również najniższe porażenie siewek. Najwyższy procent porażonych źdźbeł odnotowano u genotypów, gdzie nie stwierdzono genów Pch1 i Pch2. U tych genotypów zaobserwowano również najwyższe porażenie w teście siewkowym. Wykazano, że obecność genów Pch1 i Pch2 lub ich brak nie wpływała istotnie na plon ziarna oraz na masę tysiąca ziarniaków (MTZ). U genotypów z genami Pch1 i Pch2 stwierdzono nieznacznie wyższe wartości dla obu parametrów technologicznych.
Eyespot is one of the most important diseases of wheat (Triticum aestivum L.), caused by two pathogenic fungi Oculimacula yallundae and Oculimacula acuformis. There are several sources of resistance to this pathogen, but so far only two genes Pch1 and Pch2 have been transferred to wheat and confer the resistance. The selection of the most favorable genetic markers for determining the presence of eyespot resistance genes may improve the efficiency and accuracy in the selection of wheat genotypes resistant for this disease. The aim of the work was to determine the effectiveness of molecular markers and protein marker for Pch1 and Pch2 genes and to select genotypes of winter wheat with increased resistance in relation to plant infection in inoculation tests carried out at the seedling and adult plant stage. Plant material consist of 159 breeding lines of winter wheat and five control varieties: Artist, Kilimanjaro, Kometa, Patras and Rendezvous. To identify resistant genes, five molecular markers were used. Three for Pch1 gene (EpD1b, XustSSR2001-7DL, Xorw1) and two for Pch2 gene (Xcfa2040, Xwmc525). Considering the molecular analysis of genes, results of seedlings inoculation and the results of plant stem infestation, it was found that there were no infection symptoms of stalks in the winter wheat lines and/or varieties, in which both Pch1 and Pch2 genes were identified. In these lines/varieties, the lowest infection of seedlings was also observed. The highest percentage of infected sheaths was identified in genotypes where Pch1 and Pch2 genes were not found. The highest seedling infection was also observed for these genotypes. It was shown that the presence of Pch1 and Pch2 genes or their absence did not significantly affect the grain yield and the thousands kernels weight (TKW). Genotypes with the Pch1 and Pch2 genes showed slightly higher values for both technological parameters.

Opis:: With the shortage of water resources in recent years, water has become an important factor that limits the photosynthetic capacity and grain quality of winter wheat in the North China Plain. The experiment was conducted in 2011-2014, and the design of the two-factor split-plot was adopted, with three irrigation levels (0, 90, and 180 mm) for the main plot and three planting patterns (single-single row, single-double row, doubledouble row) for the subplot. The chlorophyll content index, net photosynthetic rate, and dry matter weight of winter wheat at different growth stages were measured, and the quality parameters of the grain were also measured after the harvest. The result indicated that irrigation increased the chlorophyll content index, net photosynthetic rate, grain protein, coarse starch and whiteness, which were favourable for producing dry matter and for seed formation. The chlorophyll content index, net photosynthetic rate, dry matter weight and gluten index of double-double row were higher than those of single-single row. Therefore, the 90 mm irrigation combined with the double-double row planting pattern is a good agronomic practice for winter wheat production, and beneficial for the improvement of flour quality in the North China Plain.

Opis:: Although Syrian high-yielding wheat cultivars grown under Mediterranean conditions include acceptable levels of resistance to biotic constraints, little is known about their susceptibility to Fusarium head blight (FHB), a harmful disease of wheat cultivation worldwide. The capacity of 16 fungal isolates of four FHB species to confer the disease on spikes and spikelets of six widely grown old and modern Syrian durum and bread wheat cultivars with known in vitro quantitative resistance to FHB was evaluated. Quantitative traits were visually assessed using spray and point inoculations for determining disease development rates, disease incidence (DI) and disease severity (DS) under controlled conditions. Differences in pathogenicity and susceptibility among wheat cultivars were observed, emphasizing the need for breeders to include aggressive isolates or a mixture of isolates representative of the FHB diversity in their screenings for selection of disease resistant cultivars. Bread wheat cultivars showed lower levels of spike and spikelet damage than durum cultivars regardless of the date of cultivar release. Overall, the six wheat cultivars expressed acceptable resistance levels to initial fungal infection and fungal spread. Quantitative traits showed significant correlation with previous standardized area under disease progress curve (AUDPCstandard) data generated in vitro. Thus, the predictive ability of AUDPCstandard appears to be crucial in assessing pathogenicity and resistance in adult wheat plants under controlled conditions. While in the Mediterranean countries the risk of disease is progressively increasing, the preliminary data in this report adds to our knowledge about four FHB species pathogenicity on a Syrian scale, where the environment is quite similar to some Mediterranean wheat growing areas, and show that Syrian cultivars could be new resistant donors with favorable agronomical characteristics in FHB-wheat breeding programs.
