AbstractCut rose stems were pretreated for 24 h with various compounds before being stored in Chrysal solution. Two experiments were conducted to study the effects of different concentrations of aluminum sulphate, ethanol and sucrose in preservative solutions and their combination on flower longevity and post-harvest physiological properties of rose (Rosa hybrida L.) cut flowers cultivars ‘Red Sky’ and ‘Blizzard’. The first experiment aimed to determine the optimum concentration of aluminum sulphate used as a biocide (0, 0.5, 1, 1.5 g·dm−3), ethanol used as a biocide and anti-ethylene factor (0, 4, 8, 12%) and sucrose used as a source of energy (0, 10, 20, 30 g·dm−3). In the second experiment, the most effective concentrations were cumulated in combinations of pretreatment solutions. Single use of chemicals: 0.5 g·dm−3 aluminum sulphate, 4% ethanol and 20 g·dm−3 sucrose extended the longevity of both cultivars by 17, 18 and 19%, respectively as compared to deionized water. In the second experiment, the preservative solution containing all three chemicals at optimal concentrations extended cut flower longevity by 30% compared to deionized water. ‘Blizzard’ has lost its commercial value by 6.6% of the time earlier than ‘Red Sky’. Generally, using a biocide, anti-ethylene and source of energy in a pretreatment solution can maintain the high quality of the cut rose flowers and their vase life.

Abstract Rose is an ornamental plant, which constitutes one of the leading cut flowers in the world. The vase life of cut Rosa hybrida L. flowers is truly short. We examined the effect of various temperatures and different time duration factors on postharvest longevity, and some other physic-biochemical characteristics and antioxidants activity. Fresh cut Rosa hybrida L. flowers were treated by water with various temperatures (23º, 42º, 47º, and 52°C) and different time duration (5, 10, 15, and 20 min). Maximum vase life (7.52 days) was related to cut flowers that were treated with 52°C for 15 min. Minimum vase life (4.46 days) was observed in cut flowers that were treated with 42°C for 5 min. Treatment of cut flowers by water with the temperature of 52°C for 15 min induced the highest water absorption, petal’s anthocyanin, and leaf’s chlorophyll. The lowest ethylene production was also obtained in cut flowers treated with 52°C for 15 min. The use of warm water (52°C) for 15 min clearly extended the vase life and most traits pertaining to the vase life of cut Rosa hybrida L. flowers.

In order to improve the post production quality of cut flowers of Rosa hybrida L. cv. Baroness, the effect of 8-hydroxyquinoline sulfate (8-HQS), silver thiosulfate (STS) and 1-methylcyclopropene ( I-MCP) were investigated. 8-HQS was used at 200 and 400 ppm with or without sucrose at 50 g LI. STS was used at 0.2, and 0.4 mM with or without sucrose at 50 g 1-I. l-MCP was used at 0.3, 0.5 and 0.7 g in-3 for 6h. The postproduction quality was improved as a result of using any chemical treatment comparing with untreated control. All the treatments of 8-HQS increased the vase life and minimized the percentage of weight loss of rose cut flowers compared to the control. The vase life was lorger when 8-HQS was combined with sucrose. The best treatment of 8-HQS was 400 ppm 8-HQS + 50 g 1-1 sucrose. STS treatment led to prolong the vase life and minimized the percentage of weight loss compared to the control. In addition, the effect was better when sucrose was added to STS. The treatment of STS at 0.4 mM + 50 g 1-1 sucrose was the best one. l -MCP treatment prolonged the vase life and lowered the percentage of weight loss at any level compared with untreated control. The best treatment in this concern was l -MCP at 0.5 g m-3 for 6h. The chlorophyll content (chl.a and chid)) of the leaves for the best treatment of each chemical was higher than the control. The treatment of STS at 0.4 mM + 50 g 1-1 sucrose gave the best results in this respect.

Abstract Phyto-hormones play a key role in regulating plant responses to stress. Cytokines are a type of phyto-hormones involved in the regulation of many important biological processes related to growth, development, and response to environmental variables. The exogenous application of cytokines increases the possibility of delaying senescence; however, this is a physiological process, and, under certain conditions, degradation processes may be triggered. The effect of 6-bencilaminopurine application and the endogenous hormonal changes involved in lilies floral stalks after their cutting were studied. In order to improve vase life and quality of Lilium longiflorum ‘Brindisi’ flower stalks, they were sprayed with 6-BAP, at a concentration of 300 ppm at pre-harvest, post-harvest, and pre- and post-harvest stages. After that, they were compared to non-sprayed control stalks. The application of 6-BAP caused endogenous hormonal changes in abscisic acid and cytokinin levels, and the most effective treatment was pre-harvest spraying. This treatment proved to be an appropriate method to improve the stalk tolerance to post-harvest stress as it delayed the appearance of senescence symptoms and reduced the speed of chlorophyll degradation with differences of up to 10% with respect to untreated stalks. In addition, the opening of flowers was delayed by up to 2 days, although there were no significant differences in total vase life.
