A method for the extraction of plant samples and the determination of total soluble carbohydrates

Abstract A method for the determination of carbohydrates in plant samples is described, in which the plants are frozen in dry ice as soon as they are cut and portions extracted with 80% alcohol in an Elco Homogenizer and the carbohydrate estimated by the anthrone reaction. A few results are given for the uptake of sucrose by plant roots from a culture solution.
