“…Waxes may have a more marked effect on inhibiting transport of gases than transport of water through the cuticle in citrus fruit (Ben-Yehoshua et al, 1985). The mode of action by which external or internal gases may alter the susceptibility of citrus fruit to develop peel damage remains unknown, though postharvest treatments modifying internal gas composition or the O 2 environmental levels may also modify non-chilling peel pitting susceptibility (Petracek et al, 1998;Ben-Yehoshua et al, 2001;Porat et al, 2004). Our results showing that treating the fruit with ethylene favours exudation of new waxes that may cover in part cracks and stomata and the fact that stomata coverage alters resistance to gas diffusion in citrus tissues (Calatayud et al, 2006) encourages new studies along these lines.…”

Elsevier Cajuste, JF.; Gonzalez-Candelas, L.; Veyrat, A.; García-Breijo, F.; Reig Armiñana, J.; Lafuente, MT. (2010) The effect of ethylene (2 L L −1 ) on total and soft epicuticular wax content and wax morphology has been investigated in mature 'Navelate' (Citrus sinensis, L. Osbeck) oranges held under non-stressful environmental conditions (22• C and constant high relative humidity (90-95% RH)). In addition, the objective of the study was to understand whether the ethylene-induced changes in epicuticular wax might participate in the beneficial effect of ethylene reducing non-chilling peel pitting, by modifying peel water, osmotic or turgor potential, or disease incidence caused by Penicillium digitatum (Pers.:Fr.) Sacc. Ethylene increased total and soft epicuticular wax content in 'Navelate' fruit and induced structural changes in surface wax that might be related to the formation of new waxes. Changes in epicuticular wax morphology, but not in its content, might be involved in the protective role of ethylene reducing non-chilling peel pitting, although the beneficial effect of the hormone is not related to water stress. Cell water and turgor potentials in freshly harvested fruit and fruit stored in air under non-stressful conditions suggest that water stress is not a limiting factor leading to the development of this physiological disorder. In addition, the results indicated that formation of new waxes in fruit treated with ethylene may partially cover stomata, cracks or areas lacking wax occurring in stored fruit and is likely to improve physical barriers to P. digitatum penetration.

“…Chinese cabbage should be stored at 98-100% relative humidity (Émond et al, 1995), which can be attained by technological strategies such as controlled or modified atmospheres; for example, 90-100% humidity has been obtained by use of perforated polyethylene bags (Émond et al, 1995;Porat et al, 2004;Yang et al, 1993). The gas composition inside the bags is another important issue (Brecht et al, 2003;Hodges and Toivonen 2008); the most important gas is the plant hormone ethylene.…”

Purpose:The aim of this study was to develop long-term storage technology for Chinese cabbage in order to extend the period of availability of freshly harvested products. The scope of the paper deals with the use of a cooler with a remote monitoring and control interface in conjunction with use of packaging film. Methods: A cooler with a real time monitoring system was designed as a low-temperature storage facility to control temperature and relative humidity (RH). The effects of storage in high-density polyethylene (HDPE) plastic boxes, 3% chitosan dipping solution, polypropylene film (PEF) with perforations, and mesh packaging bags on physiological responses were investigated. The optimal storage temperature and humidity for 120 days were below 0.5°C and 90%, respectively. Physiological and biochemical features of cabbage quality were also analyzed: weight loss, texture, and sugar salinity, chlorophyll, reducing sugar, and vitamin C contents. Results: The cooler with a remote monitoring and control interface could be operated by an HMI program. A 0.5°C temperature and 90% humidity could be remotely controlled within the cooler for 120 days. Postharvest freshness of Chinese cabbages could be maintained up to 120 days depending on the packaging method and operation of the remote monitoring system. In particular, wrapping the cabbages in PEF with perforations resulted in a less than a 5% deterioration in quality. This study provides evidence for efficient performance of plastic films in minimizing post-harvest deterioration and maintaining overall quality of cabbages stored under precise low-temperature conditions with remote monitoring and a control interface. Conclusions: Packaging with a modified plastic film and storage in a precisely controlled cooler with a remote monitoring and control interface could slow down the physiological factors that cause adverse quality changes and thereby increase the shelf life of Chinese cabbage.

“…Bagging of entire stems, inflorescences, or leaves with micro-perforated plastic film also helped stems maintain RFW for longer ( Figure 4C) and extended the vaselife of inflorescences (Table I). Bagging can improve the water status of cut Grevillea 'Crimson Yul-lo' stems by reducing water loss from inflorescence evapotranspiration and leaf transpiration, as found following the bagging of broccoli inflorescences (Brassica oleracea L., Toivonen, 1997), and apple (Watkins and Thompson, 1992) and citrus (Porat et al, 2004) fruit.…”

SUMMARYGrevillea cv. 'Crimson Yul-lo' has large bright red terminal inflorescences on leafy stems and has recognised commercial potential as a cut flower crop. A major limitation is its relatively short vase-life, often terminated by early wilting of the inflorescence despite apparently turgid leaves. An investigation of the water relations of cut Grevillea 'Crimson Yul-lo' stems revealed that the water potential of inflorescences on intact stems in vases was significantly higher (i.e., less negative) than that of leaves from day-0 to day-3 of vase-life. Thereafter, the water potential of inflorescences declined more rapidly than that of leaves, accompanied by visible wilting of the tepals and styles of individual florets. Removal of leaves from the stems reduced both water uptake and water loss, and delayed the onset of a negative water balance in the inflorescence. Bagging of entire stems, leaves only, or inflorescences only, with microperforated plastic film to reduce transpiration, reducing leaf number to reduce leaf area, or supplying abscisic acid to reduce leaf stomatal aperture, all aided relative fresh weight retention by stems and extended vase-life. Four or six leaves on a stem caused greater loss in inflorescence water content than zero or two leaves. Considered collectively, these findings show competition for water between the inflorescence and the leaves in cut Grevillea 'Crimson Yul-lo' stems contributes to the onset of inflorescence wilting and their short vaselife.3 revillea is a large genus within the family Proteaceae and it contains over 300 species (Joyce and Beal, 1999), many of which are grown world-wide (Costin and Costin, 1988;Joyce and Beal, 1999;Joyce, 2004). Many grevilleas, especially hybrids of subtropical and tropical species, are woody shrubs or small trees with attractive large, colourful inflorescences and soft, divided fern-like foliage that make them appealing as landscape plants. Their inflorescences also have commercial potential as cut flowers (Costin and Costin, 1988;Joyce, 2004), but a major limitation to their use as cut flowers is their relatively short vase-life of often less than 1 week (Faragher, 1989;Joyce et al., 1996;Joyce and Beal, 1999;Joyce, 2004). Cut stems of Grevillea 'Crimson Yul-lo' (Grevillea banksii × Grevillea 'Misty Pink') have large bright-red terminal inflorescences consisting of 90−120 florets at various developmental stages arranged along a single floral rachis ( Figure 1A, B), but the inflorescences have a vase-life of only three-four days in water.A number of factors influencing the longevity of cut Grevillea flowers have been studied.The vase-life of Grevillea 'Majestic' inflorescences harvested in Winter was generally longer than that of Summer-harvested inflorescences (Vuthapanich et al., 1993). The vase lives of Grevillea 'Sylvia' and Grevillea 'Honey Gem' were dependent upon the harvest maturity stage, with optimum maturity being characterized by opening of the lowest florets (Joyce and Beal, 1999). Addition of sucrose to vase solutions imp...
