Lipid composition of barley in relation to grain size.

Abstract

With increasing grain size, higher proportions of neutral and phospholipids and a lower glycolipid proportion are found in the lipids extracted from six-rowed winter barleys, counting for at least part of the relationship between grain size and fatty acid composition. A positive correlation between grain size and proportion of non-starch lipid, observed only in the case of two-rowed barleys, explains the less pronounced variation of the fatty acid composition with varying grain sizes for this barley type.
