 หัวเรื่อง:การเก็บรักษาดอกกุหลาบโดยวิธีแห้ง 2. ผลของการแช่โคนก้านดอกในน้ำก่อนการเก็บรักษาที่มีต่ออายุการปักแจกัน ผู้เขียน: ดร.สายชล เกตุษา, ศาสตราจารย์เกียรติคุณ ,  Sanan Dadaung สื่อสิ่งพิมพ์:pdf AbstractChristian Dior cut roses were held in distilled water for 1, 3 and 5 hours and not held in distilled water before keeping dry in sealed polyethylene bags at 3+ 1o C (80%RH). Cut roses were removed from cold room and polyethylene bags every 3 days before holding them in tap water at ambient temperature to determine their vase life, water uptake, the change in fresh weight, bent neck and blueing. The results showed that cut roses held in distilled water before keeping dry in cold room had shorter vase life than those without water pretreatment. The longer the cut rose held in water, the shorter the vase life. Water pretreatment had no effect on blueing. The effect of water pretreatment on vase life was discussed in relation to their water uptake and fresh weight changes. |
หัวเรื่อง:การเก็บรักษาดอกกุหลาบโดยวิธีแห้ง 1. ผลของอุณหภูมิต่ำและวิธีการห่อและบรรจุที่มีต่อคุณภาพ อายุการเก็บรักษา และอายุการปักแจกัน ผู้เขียน:ดร.สายชล เกตุษา, ศาสตราจารย์เกียรติคุณ, Sanan Dadaung สื่อสิ่งพิมพ์:pdf AbstractEffects of low temperature and packing method on quality and vase life of Christian Dior cut roses were studied. Cut roses were packed with the following methods : wrapping with newspaper and both ends opened, wrapping with newspaper and both ends opened before packing in corrugated box, placing in perforated polyethylene (PE) bag with sealing and packing in corrugated box, placing in perforated PE bag with sealing and placing in non-perforated PE bag with sealing, then kept dry at 3?1?C (80% RH) and 10?1?C (73% RH). Cut roses were removed from cold room every three days to evaluate their quality, storage life and vase life. The results showed that cut roses in non-perforated PE bag with sealing kept dry at 3?1?C had the best quality and longest storage life of 12 days. Cut roses stored under the above conditions had no signicant difference in vase life from that of freshly cut roses without storage. Cut roses kept dry at 10?1?C had the storage life less than three days and their vase life at room temperature was very short. |
