Publisher's Synopsis
Excerpt from The Effect of Large Applications of Commercial Fertilizers on Carnations
Examination was made for starch in carnation leaves taken from the plant after a day of sunshine by boiling them for some time in alcohol, then in water, and testing leaf sections with an alcoholic solution of iodine; starch was found to be plentiful. Comparative determinations of the starch content* were made upon the residues from sugar extractions, using a diastase solution prepared by extraction of ground malt with mono sodium phosphate solution at ice - box temperature, but not dialyzed. Fifty cubic centimeters of water were added to the residue and the starch gelatinized by boiling for five minutes, with continuous stirring. After cooling to 5 cc. Of the diastase solution were added with a pipet and digestion allowed to proceed for an hour. The mixture was again heated to boiling and 5 cc. Of diastase again added and after an hour the mixture was filtered and washed thoroughly. The maltose in the filtrate was hydrolyzed to glucose by the modified Sachsse method and glucose deter mined with Fehling's solution, correction being made for maltose in the diastase solution. The values obtained for samples from sets of 2 - 10 - 15 and 2 - 17 - 15 are shown in Table XVII. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
