Effects of pretreatment, packaging materials and temperature during transportation on quality of cut rose (Rosa hybrida L.) ´Mary de Vor´ were studied. Stem ends of cut roses were pretreated with 3 mM Al₂(SO₄)₂ solution for 10 minutes followed by immersion in 3% sucrose solution for 4 hours, and in tap water for 2 hours. Then they were simulated for transportation with corrugated cardboard box (CCB) package with polyethycene film (PEF) lining with wet newspaper (WNP) and CCB without lining at 5 and 25℃ for 24 hours. These flowers, compared to the fresh cut rose control, had shortened vaselife, decreased flower opening, and increased bent neck. For transportation temperature, 5℃ was much better than 25℃. The WNP + PEF + CCB showed a small variation between 5℃ and 25℃, but the CCB alone showed a large variation in quality between 5℃ and 25℃ for 5℃ kept the freshness until middle of experiment while 25℃ lost most of the freshness from the early days of experiments. Pretreatment with aluminum sulfate and sucrose solution was effective both in cut roses transported and the control, and among transported cut roses, it was more effective at 25℃ than at 5℃. Therefore, cut ´Mary de Vor´ rose was the best when transported at 5℃ in the package of WNP + PEF + CCB after pretreatment with 3 mM Al₂(SO₄)₃ and 3% sucrose solution.
