Dormant ‘Viva’ rose bushes kept at 0° or 5°C were subjected to 0, 1, 10, 100, or 1000 ppm ethylene for 4 weeks, then planted in containers and forced in the greenhouse. At planting, ethylene damage was not apparent, except to the plants exposed to the combination of 5° and 1000 ppm ethylene. However, after 5 weeks of growth, there was progressively more cane mortality and less budbreak as ethylene concentrations were increased, with more damage for the 5° than the 0° treatments.
) have suggested that total sugar content and sugar in the basal, middle, and apical sections of fresh-cut bamboo shoots initially decreased and then changed variably thereafter in different sections of the shoots during storage at 4 °C for 16 d. Kozukue

Storage potential is generally evaluated by measuring fruit quality before and after storage. A cultivar with the smallest change in fruit quality between at harvest and after storage or a cultivar with acceptable levels of quality as evaluated by
cuttings of many species. Most of the published research has focused on methods for improving the storage longevity of cuttings by delaying postharvest leaf abscission and senescence. Investigations include the use of cold storage treatments ( Behrens, 1988
stored from 1 to 5 °C with 85% to 95% relative humidity (RH) ( Lutz, 1938 ; Silva et al., 1994 ; Takeda et al., 1983 ; Walker et al., 2001 ). The use of sulfur dioxide storage treatment on the quality of bunch grapes is cultivar-specific and with
