Summary: Foliar nitrogen application is an effective strategy for improving protein content and quality in wheat kernels. The specific effects of different forms of nitrogen are still unclear, but NO3 and urea have shown better results. Manipulating the source-sink relationship can optimize wheat protein accumulation and quality formation.

Summary: This review summarizes the forms, distribution, biosynthesis pathways, methods for determining antioxidant activity of phenolics in wheat grain, as well as the factors influencing the content of phenolic components in grains and the bioavailability of phenolics under different food processing methods. Future research directions include increasing wheat grain phenolic content through genetic engineering and improving bioavailability through proper food processing.

Summary: Late stage nitrogen applications can increase grain yield and N uptake in wheat, but their effectiveness in mitigating the decrease in grain protein content caused by elevated CO2 concentrations is unclear. Split N applications enhanced gluten protein content by altering N distribution, but did not alleviate the negative effect of elevated CO2 on grain protein content.

Summary: The spatial distribution of irrigation and nutrients in soil significantly affects crop growth and water productivity. Applying irrigation in deep soil layer can increase grain yield and water productivity under water deficit conditions, while locating nutrients in deep soil layer may decrease crop yield and water productivity.

Summary: This study aimed to address the unbalanced coordination of irrigation and fertilization for winter wheat in the eastern North China Plain. The results showed that drip irrigation and fertilization at the jointing, anthesis, and filling with a moisture replenishment depth of 10 cm significantly increased yield, water use efficiency, nitrogen use efficiency, and maintained high grain protein content and yield. This fertigation method is recommended for reducing irrigation water and nitrogen input in the eastern North China Plain.

Summary: The study found that increasing nitrogen application significantly increased the tillers per plant, while irrigation had a significant impact on spike density and grain number per spike, with uncertainty on the effect on thousand kernel weight. Nitrogen had a stronger influence on yield increase than irrigation, and deficit drip irrigation combined with 170 kg nitrogen per hectare was identified as the best management strategy.

Summary: Climate change reduces water availability in agricultural areas, while agrivoltaic systems help manage energy transition. This study analyzed the carbon isotopic composition in grains and grain yield of winter wheat in an agrivoltaic system, finding that although grain yield did not significantly differ compared to a reference site, the carbon isotopic composition showed significant differences, indicating drought mitigation effects.

Summary: The lower yield of second wheat grown after wheat may not only be attributed to fungal disease occurrence, but also to other factors. This study found that growing oilseed rape as a pre-crop can increase subsoil root length density of the subsequent wheat crop, and the aboveground biomass and yield of wheat are affected by the crop rotational position.

Summary: This study investigated the impact of extreme high-temperature stress on wheat grain yield and quality, focusing on grain protein concentration as a key factor. The research found that high-temperature stress significantly reduced total above-ground nitrogen and accelerated grain nitrogen accumulation, with more sensitivity at anthesis compared to grain filling. The study also enhanced a crop model to better simulate nitrogen dynamics and grain quality under high-temperature stress, reducing uncertainties in assessing climate change effects on wheat grain quality.

Summary: The quality of wheat grain, which is crucial for human nutrition, is often neglected when focusing on crop production in stressed environments. Climate change, with combined stresses such as elevated CO2 concentrations and extreme climatic events, affects the quality and composition of wheat grain. This study highlights the limited data and lack of global efforts in assessing climate risks on wheat grain quality. Climate-change events, including eCO(2), heat, drought, salinity stress, and their combinations, alter various aspects of wheat grain quality, such as weight, nutrient content, fiber content, protein composition, starch granules, and free amino acid composition. Different stress types and exposure conditions also influence grain quality components. Impairment of wheat productivity and degradation of grain quality can occur due to disrupted nutrient allocation and assimilation under rapid climate shifts.

Summary: This study investigated the qualitative characteristics of winter wheat treated with ozonated water. The results showed that ozonated water treatment effectively reduced mold fungi in the grains and flour, improving the mycological safety of the flour samples. However, it did not significantly affect the basic composition of the winter wheat grains.

Summary: This study assessed the variations in grain yield and protein content within two commercial durum wheat cultivars and found that high-yielding and high-protein lines could be obtained through selection. The experiments revealed significant variation within already improved commercial cultivars. Ultra-low plant density cultivation allowed for efficient selection and differentiation among individual plants.
