Abstract

There have been few investigations of the anatomical and morphological characteristics of cucumber peduncles. Judson (3) reported that there are 10 vascular bundles entering the pistillate cucumber flower and the resulting fruit. Leonard (4), Bingley et al (1), and Burnham and Peterson (2) observed varietal and seasonal differences in the force required to pull the pickling cucumber fruit from its stem. The variety ‘Wisconsin SMR-12’ was easy to pick while Ohio MR-17’ was among those requiring a relatively high picking force.

Abstract

An instrument for determining the force required to pull the peduncle from a cucumber fruit is described. Picking force was studied using the pickling cucumber cultivars Wisconsin SMR-15, Ohio MR-17, and Wisconsin SMR-12 in 3 positions in the picking force instrument on 3 harvest dates. Picking force was more highly correlated with fruit length than fruit weight or diameter. Regression coefficients of picking force on fruit length were homogeneous for cultivars, stem positions, and harvest dates. Significant differences in mean picking forces were detected for cultivars, position of the fruit in the picking force instrument, and harvest dates. The cultivar sequence of increasing picking force was ‘Wisconsin SMR-12’, ‘Wisconsin SMR-15’, and ‘Ohio MR-17’.
