Metabolite profiling of wheat flag leaf and grains during grain filling phase as affected by sulfur fertilisation.

Increasing prices for wheat products and fertilisers call for an adjusted agricultural management to maintain yield and to improve product quality. With the increased use of sulfur-free fertilisers in modern cropping systems and the decrease of atmospheric sulfur emissions by industry, sulfur has become a major limiting factor for crop production. The presented data showed that by using GC-MS it was possible to quantitatively detect a set of 72 different metabolites including amino acids, organic acids, sugars, sugar phosphates, and sugar alcohols, phenolic compounds and nucleotides from wheat grains and flag leaves of a pot experiment.

Time-dependent distribution of sulphur, sulphate and glutathione in wheat tissues and grain as affected by three sulphur fertilization levels and late S fertilization.

Sulphur (S) fertilization has beneficial effects on yield and protein composition of mature wheat kernels. However, to understand the impact of S fertilization on storage protein composition, synthesis of S-containing compounds and their distribution during grain development has to be examined. A pot experiment with Triticum aestivum cultivar Türkis under three S fertilization levels (0 g, 0.

Quantitative protein composition and baking quality of winter wheat as affected by late sulfur fertilization.

Increasing prices for wheat products and fertilizers, as well as reduced sulfur (S) contributions from the atmosphere, call for an improvement of product quality and agricultural management. To detect the impact of a time-dependent S fertilization, the quantitative protein composition and the baking quality of two different wheat cultivars, Batis and Turkis, were evaluated. The glutathione concentration in grains serves as a reliable marker of the need for added S fertilizer.
