THE APPLICATION OF THE TOTAL AVAILABLE CARBOHYDRATE METHOD TO THE STUDY OF CARBOHYDRATE RESERVES OF SWITCH CANE (ARUNDINARA TECTA)

Abstract
A study of the analytical aspects of the method for the detn. of total available carbohydrates (H. Weinmann, Plant Physiol. 22: 279-290. 1947) and the applicability of the method to the study of the carbohydrate reserves in the A. tecta plant has been made. Results obtained by this method compared very favorably with those obtained by ordinary fractionation studies. The method is rapid and lends itself to routine use. The total available carbohydrate and total sugar content of stem, leaf and rhizome samples collected over a period of 1 yr. are given. The rhizomes served as the principal storage organs, however the perennial stems served in a similar capacity to a much lesser extent. The total available carbohydrates in the rhizomes varied from 9% in June to 26% in Oct.
