Improved Zn bioavailability by its enhanced colocalization and speciation with S in wheat grain tissues after N addition

Insights into the Functional Components in Wheat Grain: Spatial Pattern, Underlying Mechanism and Cultivation Regulation

“…According to Xue et al, the amount of Fe increased in wholemeal and wheat brans but dropped in refined flour [74], indicating that raising the concentration of Fe in flour via nitrogen application was difficult. In contrast, the addition of N fertilizer improved the concentrations and bioavailability of grain tissues, especially in the crease region and the endosperm [75]. Dong et al observed that foliar spraying with zinc fertilizer at 5, 15, and 25 days after anthesis may successfully enhance the Zn content in different layers of grain, with the rise being larger in the outer layer of grain.…”

Elemental Imaging of Fertilized ZnO NP Wheat Endosperms Using Laser Ablation–Inductively Coupled Plasma Optical Emission Spectrometry

“…Some methods, i.e., synchrotron-based XAS analysis, micro X-ray fluorescence, and X-ray absorption near-edge structure, have been used for elemental imaging analysis of wheat grain. − However, these methods mainly focus on the elemental qualitative or semiqualitative imaging analysis. The application of the above technologies to elemental quantitative distribution analysis in wheat grain is still limited.…”
