Abstract
Mean daily stomatal resistance was higher (58%; to 384%), photosynthesis values lower (11% to 49%), and crop water stress index values higher (92% to 95%) in stressed cucumber (Cucumis sativus L.) plants than in irrigated control plants in three experiments performed in 1987 and four in 1988. Pillowy fruit disorder (PFD) was more frequent (110% to 150%) and more severe (59% to 81%) in freshly harvested fruits from stress plots when compared to controls. No after-storage differences in PFD were detectable between water stress treatments. Mean PFD ratings of processed fruit following postharvest storage at 26.5C and either 60% or 75% relative humidity were significantly higher than ratings of fruit stored at either 10.5 or 15.5C and 85% relative humidity. The progressive development of pillowy and the observed enhancement of PFD symptoms following storage at higher storage temperatures indicated that postharvest changes can occur in fruit mesocarp tissue and that the development of PFD can be altered, to some extent, during storage. Negative correlations (- 0.18 to - 0.78) between fruit quality and PFD ratings suggested that these changes can affect processed product quality. Pillowed tissue of processed fruit was significantly softer (33% to 39%) than nonpillowed tissue.
