Historical publication digitized 2013 by Internet Archives [for Agriculture and Agri-Food Canada]. Includes bibliographical references. "Carotin concentrations were determined spectrophotometrically, on experimentally milled flours from a series of spring wheat varieties grown on dry land and on irrigated land in 1929. Flours milled from dry land wheat were higher in carotin concentrations than flours milled from irrigated land wheat. An inherent varietal influence contributed to the carotin concentrations obtained in the dry land samples in comparison with the carotin concentrations obtained in the irrigated land samples ... Samples of the same variety may be expected to vary considerably in carotin concentration of the wheat and of the flour milled from the wheat. Higher values appear to be associated with lack of plumpness as determined by test weight per bushel measurements"--Summary, p. 32. gccst Wheat Canada. Department of Agriculture.
