Résumé

Fruit from eight plant introduction lines, 12 F1 hybrids of crosses between chilling-sensitive and chilling-resistant lines and two commercial cultivars of cucumber (Cucumis sativus L.) were stored for 7 days at 1 or 4 °C followed by 2 days at 24 °C and evaluated for chilling injury. Criteria used included visible pitting, decay, weight and electrolyte loss, chlorophyll fluorescence ratios and respiration rates. It is concluded that low temperatures do not affect all biochemical and physiological processes of cucumber to the same extent. Furthermore, there is a continuum of sensitivity of each process to low temperature, and whether a cultivar is deemed to be chilling-sensitive or chilling-resistant depends on which particular biochemical or physiological process is evaluated.
