The present investigation was carried out during 2006 and 2007 seasons to study the effect of some preservative solution treatments, packaging materials and cold storage periods in keeping quality of Solidago canadensis. The obtained results indicated that, spraying flowers with 5 ppm BA +1ml/L Voporgard then placed in 2% sucrose+200 ppm 8-HQS solution, significantly increased the vase life, maximum increase of fresh weight %, decreased bacterial counts on vase solution, increased chlorophyll

While spraying with 5 ppm BA +1ml/L Voporgard then placed in 200 ppm 8-HQS solution recorded the highest water uptake. Packaging with Kraft paper and storage at 3 °C for I week increased vase life, maximum increase of fresh weight %, and recorded the highest water uptake. The treatment of interaction between packaging with Tissue paper and storage at 3 °C for I week recorded the longest vase life, the highest value of maximum increase of fresh weight % and highest amount of water uptake. The treatment of interaction between packaging with Kraft paper and storage at 3 °C for I week resulted decreased in bacterial counts on vase solution, increased chlorophyll content, carotenoid, total, reducing, non-reducing sugar and decrease proline.
