Abstract
Abstract Fruits of several cucumber (Cucumis sativus L.) cultivars were analyzed for sugar and dry matter content shortly after harvest and after a 3-day storage period (16°C). The storage period produced no consistent pattern of differences in reducing and total sugar and dry matter content Large fruits (3.81–5.08 cm diameter) had more sugar than small fruits (<2.70 cm diameter). Fructose, glucose and sucrose were shown to be present Storage had little quantitative effect on sugar concentration. Additional data from other seasons confirmed that nearly all of the sugar present was reducing sugar. Correlations between refractive index and reducing sugar were from .42 to .93 in one experiment and from .05 to .84 in another. The sugar concentration was higher in locule tissue than in the carpel wall tissue. The sugar concentration of the fruit was generally less than 3% and refractive index expressed as percent soluble solids does not appear to be an accurate indicator of sugar content.
