Identification and Distribution of Some Carbohydrates of the Muskmelon Plant

The concentration of fructose, glucose, sucrose, raffinose, and stachyose in the leaves, stem, and fruit of the muskmelon plant ( Cucumis melo L.) was determined using paper and gas chromatography. Stachyose was the predominant sugar in the leaves but was absent in the developing fruit. Most of the 14 C label in 14 CO 2 -treated leaves was associated with stachyose, while the 14 C label in the fruit was associated with fructose and glucose. The concentration of stachyose was highest in the leaves, intermediate in the stem, and lowest in the fruit.
