Abstract
This investigation was conducted to study the effect of wet and dry cold storage (at 4°C for 6 days) and spraying flowers before storage with essential oils of Peppermint and Clove at: zero(control),1 and 2ml/L on Ageratum Hostonianum "Blue Horizon" cut flowers aiming for keeping quality and longevity during two successive seasons of 2013 and 2014. The results indicated that, spraying flowers with oils ,either stored wet or without storage, increased vase life and water uptake when compared with dry stored flowers. Vase life was increased significantly when flowers stored wet compared with non-stored flowers. Additionally, flowers sprayed with Peppermint oil (2ml/L) before wet cold storage, increased in vase life, water uptake and maximum increase in fresh weight in the two seasons. During cold storage period, flowers stored wet and sprayed with 2ml/L Peppermint oil were maintained the highest values of total chlorophyll content and the lowest values of fresh weight loss during storage period as compared with the flowers stored dry. A significant decrease in total chlorophyll values induced with dry cold storage after 6th days in vase life period. According to these results, it could be recommended that spraying Ageratum hostonianum flowers with Peppermint or Clove essential oils at (1 or 2ml/L) before wet cold storage or without storage resulted in extending the vase life and keeping quality.
