SOLUBLE CARBOHYDRATES OF WHEAT STEMS AND LEAVES

Abstract

Chromatographic evidence indicated that glucose, fructose, and sucrose were present in wheat stems and leaves at stages of growth from early shot blade to maturity. A number of non-reducing oligosaccharides soluble in 80% ethanol were also present in both leaves and stems during this period. Simultaneously, at least one water-soluble oligosaccharide which is insoluble in 80% ethanol appeared in the stems. All oligosaccharides examined produced only glucose and fructose upon complete hydrolysis with invertase or acid.
