The objective of the present study was to show the relationship between total soluble solids (TSS) and dry matter content (DMC) at harvest and of shelf life of cucumber (Cucumis sativus L.) cultivars. Two groups of cultivars with different production cycles were studied during two agricultural seasons. Sample cucumbers were stored for 28 d in the dark, at 10 °C, and 85–95 % relative humidity. The DMC, TSS, and commercial quality were determined every seven days. The crop cycle, harvest month, type of cultivar, and storage time affected cucumber DMC and TSS. The TSS content showed a linear relationship with DMC, which was maintained from harvest to senescence. In addition, the values of these two parameters decreased progressively during storage. The DMC and TSS at the time of collection may influence the shelf life of cucumbers, the higher their contents at harvest, the longer the shelf life. Therefore, the TSS and DMC of cucumbers measured at harvest can be used as indicators of cucumber shelf life.

本研究的目的是展示总可溶性固形物 (TSS) 和收获时干物质含量 (DMC) 之间的关系以及黄瓜 ( Cucumis sativusL.) 栽培品种。在两个农业季节研究了具有不同生产周期的两组栽培品种。黄瓜样品在黑暗中、10°C 和 85-95% 的相对湿度下储存 28 天。DMC、TSS 和商业质量每 7 天测定一次。作物周期、收获月份、品种类型和储存时间影响黄瓜 DMC 和 TSS。TSS含量与DMC呈线性关系，从收获到衰老一直保持。此外，这两个参数的值在储存过程中逐渐降低。采集时的 DMC 和 TSS 可能会影响黄瓜的保质期，收获时含量越高，保质期越长。因此，收获时测量的黄瓜的 TSS 和 DMC 可以作为黄瓜保质期的指标。
