Relationships between some hordein components and quality properties in two Tunisian barley varieties as influenced by nitrogen fertilisation
Two Tunisian barley varieties, Martin and Rihane, differing by their degrees of adaptation to the environmental conditions and grain yield potential, were grown under different levels of nitrogen fertilisation.

Summary: | Two Tunisian barley varieties, Martin and Rihane, differing by their degrees of adaptation to the environmental conditions and grain yield potential, were grown under different levels of nitrogen fertilisation. The effect of N supply on the hordein components (expressed in mg per albumen) was determined by Nu-PAGE electrophoresis using the MOBS running buffer and densitometric analysis. Increasing N fertilisation increased the protein content by increasing the amount of C-hordeins. The sub-fraction BIII of high molecular weight B-hordeins appeared as the best criterion for distinguishing between the two barley varieties, and its quantification could be recommended for the understanding of the quality properties of the barley response to different environmental conditions, particularly N fertilisation. |
