Laboratory germinability and germination energy of spelt grain depending on fertilization and storage

Spelt is a promising crop for processing, as valuable micronutrients are evenly distributed in its grain, while in modern wheat bread varieties they are concentrated in the hull, aleurone layer and germ. Its proteins contain more gliadins and fewer glutenins, making gluten weak, but better digestible in the human body. Purpose and objectives: to assess the germinability and germination energy of spelt depending on the types, doses and timing of nitrogen fertilization and storage period. Materials and methods. The study was conducted in the Laboratory of Evaluation of Grain and Grain Product Quality of the Chair of Grain Storage and Processing Technologies of Uman National University of Horticulture. We studied winter spelt variety Yevropa created by hybridization of Triticum aestivum L. with Triticum spelta L. Fertilizers were ammonium nitrate, ammonium sulfate, granular superphosphate, and potassium chloride. Results and discussion. The study found that before storage the germination energy of grain was 87–90% depending on fertilization. Nitrogen fertilizers significantly increased this indicator. When grain was stored for 30 and 90 days, the germination energy was the highest and amounted to 98–99%. Longer storage significantly decreased this parameter. It was the lowest after P60K60 application: 95%, 92% and 87% when grain was stored for 180, 270 and 360 days, respectively. Before and after 30- and 90-days storage of spelt grain, this parameter amounted to 99% and regardless of fertilizers. The lowest laboratory germinability was observed after 1-year storage of grain (81–84% depending on fertilizers). This indicator was the highest with P60 + N120, amounting to 84%, and the lowest without fertilizers or with N60S70 + N60. Conclusions. The germination energy of spelt grain was found to be the highest after 30- to 180-day storage (96-99%). This indicator was most affected by nitrogen fertilizers. After 360-day storage, the germination energy reduced to 87–91% depending on the type and timing of nitrogen fertilization. The laboratory germinability of spelt grain of 97–99% maintained from harvesting to storage day 180. When spelt grain was stored in sealed containers without temperature control, this indicator gradually decreased to 81–84% for 360 days of storage, depending on fertilizers

The article presents the study results of spelt wheat grain baking properties depending on fertilization and storage period. Europe (huskless) winter spelt wheat variety obtained by hybridization of Triticum aestivum L./Triticum spelta L. was studied. For fertilization, ammonium nitrate, ammonium sulfate, granular superphosphate, potassium chloride were used. Spelt wheat grain was stored for a year without air access at an unregulated temperature regime dry (moisture content during storage – 13.0–13.5 %) in airtight polyethylene sleeves in the conditions of usual storage. It was found that spelt wheat has a high response to the application of nitrogen fertilizers. The protein content increased from 18.6 to 22.8 % in P60K60 + N120 variant. The spelt wheat grain quality varied depending on the storage period. Thus, before storage, the gluten content was 41.1–50.4 % depending on the fertilizer variant. The lowest indicator was in the control variant and for P60K60 introduction – 41.1–41.2 %. In other fertilizer variants, the gluten content was at the level of 49.1–49.9 %. The largest was in P60K60 + N60S70 + N60 –50.4 % variant or 9 % compared to the control. Storage had a positive eﬀect on the gluten content in spelt wheat grain as its content increased signifcantly. It can be explained by the post-harvest grain ripening, in the process of which the protein-proteinase complex changes due to the oxidizing action, oxygen, in particular. Thus, after storage for 30 days, this indicator was 41.8–52.1 % depending on the experiment variant. It was the largest when N60S70 + N60 was applied – 52.1 %, and the smallest in the variant with no fertilizers and with phosphorus-potassium (P60K60) fertilizer – 41.8–42.3 %. These indicators exceeded the gluten content before storage by an average of 1.2 abs. %. The content of protein and gluten-forming fractions is the highest after storage for 90 days. These indicators almost did not change after 180–270 days of storage. After 360 days they decreased to the grain quality indicators before storage. The gluten deformation index increased to 105–108 units of GSI instrument or by 4–8 % depending on the fertilization compared to fresh grain. Gluten moisture content decreased after 30 days of grain storage, and then increased to 68.0–69.8 % after 360 days, depending on the experiment variant. The grain acidity also increased from 3.0 to 4.0–4.1 degrees. Key words: spelt wheat, fertilization, storage, protein, gluten, dynamics, moisture content, acidity.

Abstract The purpose of this study is to evaluate the condition of a collection of Bulgarian common wheat varieties under ex situ controlled storage after a ten-year period. The studied materials are characterized by high vitality, without negative changes that will lead to the loss of original germplasm. The established moisture in the seeds is high for the purpose of controlled storage. When it rises above 12,5%, a decrease in the values of germination energy is observed. Higher control of initial moisture and germination is required prior to entering the seeds for storage under ex situ conditions.

The use of high-quality seeds is essential to maintain high rates of production and productivity. The physiological quality of seeds obtained in the field is directly correlated to storage conditions and storage time. This study aimed to evaluate the physiological quality of soybean seeds in relation to different field environments (seed lots) and storage time. Commercial lots of seeds of the soybean cultivar M8349 IPRO were stored for three and six months. Seed moisture content was determined before and after accelerated aging, along with seed germination percentage and vigour evaluations performed before and after each storage period. The experiment was carried out as a completely randomised factorial design (10 × 3): with ten seed lots and three storage periods. The data were analysed by ANOVA, and the means of four independent replicates for each parameter evaluated were compared using the Scott-Knott test at 5% probability (P ≤ 0.05). Our results revealed that the low altitude regions where the seed samples were collected are suitable for soybean seed production with high physiological quality. Seed storage for six months does not cause a significant reduction in subsequent soybean seed field performance.

The effect of testing temperature and storage period on the polarization fatigue properties of poly (vinylidene fluoride-trifluoroethylene) (P(VDF–TrFE)) ultrathin film devices were investigated. The experimental results show that, even after stored in air for 150 days, the relative remanent polarization (Pr/Pr(0)) of P(VDF–TrFE) of ultrathin films can keep at a relatively high level of 0.80 at 25 °C and 0.70 at 60 °C. To account for this result, a hydrogen fluoride (HF) formation inhibition mechanism was proposed, which correlated the testing temperature and the storage period with the microstructure of P(VDF–TrFE) molecular chain. Moreover, a theoretical model was constructed to describe the polarization fatigue evolution of P(VDF–TrFE) samples.

Ultra High Temperature

Age gelation is a major quality defect in ultra-high-temperature (UHT) pasteurized milk during extended storage. Changes in plasmin (PL)-induced sedimentation were investigated during storage (23 °C and 37 °C, four weeks) of UHT skim milk treated with PL (2.5, 10, and 15 U/L). The increase in particle size and broadening of the particle size distribution of samples during storage were dependent on the PL concentration, storage period, and storage temperature. Sediment analysis indicated that elevated storage temperature accelerated protein sedimentation. The initial PL concentration was positively correlated with the amount of protein sediment in samples stored at 23 °C for four weeks (r = 0.615; p < 0.01), whereas this correlation was negative in samples stored at 37 °C for the same time (r = −0.358; p < 0.01) due to extensive proteolysis. SDS-PAGE revealed that whey proteins remained soluble over storage at 23 °C for four weeks, but they mostly disappeared from the soluble phase of PL-added samples after two weeks’ storage at 37 °C. Transmission electron micrographs of PL-containing UHT skim milk during storage at different temperatures supported the trend of sediment analysis well. Based on the Fourier transform infrared spectra of UHT skim milk stored at 23 °C for three weeks, PL-induced particle size enlargement was due to protein aggregation and the formation of intermolecular β-sheet structures, which contributed to casein destabilization, leading to sediment formation.

Tandem Duplications

Abstract During the development of disomic additions of rye (Secale cereale L.) chromosomes to wheat (Triticum aestivum L.), two reverse tandem duplications on wheat chromosomes 3D and 4A were isolated. By virtue of their meiotic pairing, the reverse tandem duplications initiated the chromatid type of the breakage-fusion-bridge (BFB) cycle. This BFB cycle continued through pollen mitoses and in the early endosperm divisions, but no clear evidence of its presence in embryo mitoses was found. The chromosome type of BFB cycle was initiated by fusion of two broken chromosome ends resulting in a dicentric or a ring chromosome. Chromosome type BFB cycles were detected in embryo mitoses and in root tips, but they did not persist until the next meiosis and were not transmitted to the progeny. Active BFB cycles induced breakage of other wheat chromosomes that resulted in additional reverse tandem duplications and dicentric and ring chromosomes. Four loci, on chromosome arms 2BS, 3DS, 4AL, and most likely on 7DL, were particularly susceptible to breakage. The BFB cycles produced high frequency of variegation for pigmentation of the aleurone layer of kernels and somatic chimeras for a morphological marker. With the exception of low mutation rate, the observed phenomena are consistent with the activity of a Ds-like element. However, it is not clear whether such an element, if indeed present, was of wheat or rye origin.

Nitrogen Fertilizers

Sustainability of rice production under flooding conditions has been challenged by water shortage and food demand. Applying higher nitrogen fertilization could be a practical solution to alleviate the deleterious effects of water stress on lowland rice (Oryza sativa L.) in semi-arid conditions. For this purpose, field experiments were conducted during the summer of 2017 and 2018 seasons. These trials were conducted as split-split based on randomized complete blocks design with soil moisture regimes at three levels (120, 100 and 80% of crop evapotranspiration (ETc), nitrogen fertilizers at two levels (N1—165 and N2—200 kg N ha−1) and three lowland Egyptian rice varieties [V1 (Giza178), V2 (Giza177) and V3 (Sakha104)] using three replications. For all varieties, growth (plant height, tillers No, effective tillers no), water status ((relative water content RWC, and membrane stability index, MSI), physiological responses (chlorophyll fluorescence, Relative chlorophyll content (SPAD), and yield were significantly increased with higher addition of nitrogen fertilizer under all water regimes. Variety V1 produced the highest grain yield compared to other varieties and the increases were 38% and 15% compared with V2 and V3, respectively. Increasing nitrogen up to 200 kg N ha−1 (N2) resulted in an increase in grain and straw yields by 12.7 and 18.2%, respectively, compared with N1. The highest irrigation water productivity (IWP) was recorded under I2 (0.89 kg m−3) compared to (0.83 kg m−3) and (0.82 kg m−3) for I1 and I3, respectively. Therefore, the new applied agro-management practice (deficit irrigation and higher nitrogen fertilizer) effectively saved irrigation water input by 50–60% when compared with the traditional cultivation method (flooding system). Hence, the new proposed innovative method for rice cultivation could be a promising strategy for enhancing the sustainability of rice production under water shortage conditions.

Bottom ash (BA) is an industrial solid waste formed by the burning of coal. The environmental problems and storage costs caused by this waste increase with every passing day. In this study, the use of BA as an additive (clay substitute) in fired brick production was investigated. The study consisted of two stages. In the first stage, cylinder blocks were produced from clay used in brick production. The second stage was the examination of the experimental substitution of clay with 10, 20, 30 and 40% BA. Samples were fired at 900, 1000, 1100 and 1150 °C to produce fired brick samples. The unit weight, compressive strength (before and after freeze–thawing) and water absorption were analyzed for the samples. The unit weight values decreased in the samples containing BA. The mechanical properties met the conditions prescribed in the relevant standards; i.e., all of the samples fired at 1100 and 1150 °C had a sufficient compressive strength over 20 MPa. The high potential of fired bricks for the construction industry was proved. BA can be used as a clay substitute, while the developed protocol can be used to effectively produce fired bricks.
