Abstract
The alcohol-soluble amino acids of imbibed Rideau wheat (Triticum aestivum) grains exposed to 2 C was modified by sonication at 5 kHz for 4 wk. Although the free amino acid content of this fraction was unchanged, the percentage of glycine and aspartic acid was higher in the endosperm of nonsonicated controls. By contrast, the sonicated series always had comparatively more alanine in the embryo and less in the endosperm than comparable control grains. The amount of glycine and alanine was always substantially higher whereas asparagine content was lower in sonicated endosperm tissue as compared with untreated controls. Generally, the amino acid content of both the embryo and endosperm was higher in the control series.
