Use of Carbohydrate Reserves During Growth from Cuttings of Grape Vine

Abstract

Changes in the carbohydrate status of cuttings of vines (Vitis vinifera cv. Sultana) from which plants were developed in a glasshouse were studied by dry weight measurements and analysis for sugars, starch, and hemicellulose. Treatments consisted of one-node cuttings and two-node cuttings (differing initial quantities of carbohydrate reserves) and one-node cuttings with shade (carbohydrate stress).
