Fruit textures of Beit Alpha, greenhouse, Japanese, pickling, and slicer-type cucumbers.

摘要

Physical properties (flesh firmness, placental firmness, peel toughness, crispness index, ratio of placental firmness to flesh firmness (relative placental firmness)), and ratio of peel toughness to flesh firmness (relative peel toughness) were determined for 5 cucumber cultivars/types (cv. Beit Alpha, greenhouse, Japanese, pickling, slicer). Time-dependent changes in physical properties were also determined. Japanese cucumbers had firmer flesh and placenta, lower relative peel toughness, and the highest crispness. cv. Beit Alpha and greenhouse cucumbers had softer flesh, placenta and peel, and the lowest crispness. Pickling cucumbers had firmer (tougher) flesh, placenta and peel. Slicer cucumbers had softer flesh and placenta, and the toughest peel. Physical properties of sequentially harvested cucumbers varied widely, indicating that texture was strongly affected by cultivar (or type) and fruit size (i.e. timing of harvest).
