There have been very many methods suggested from time to time for the determination of reducing sugars, and considerable difficulty has been experienced in obtaining one which is sufficiently foolqxoof to give satisfactory results in the hands of all operators. In 1936 von Stieglitz and Home 11) reviewed several methods and recommended the electro* metric determmat~on of the end point with the ...

It is well known that some reducing substances, resembling true sugars in their behavior, occur almost invariably in plant extracts and may introduce great errors into the estimation of those sugars. Since the soluble sugars commonly present in plants (glucose, fructose, sucrose and maltose) are easily fermented by yeast, this phenomenon suggests itself as a convenient and practicable method fo...

The aim of this study was to analyze the effect of drought stress on the kinetics of leaf elongation in relationship to the variation of sugar concentrations and their net deposition rates along the elongation zone of leaf 4 of durum wheat plants. Plants were grown in soil in a naturally illuminated greenhouse, and water...
