Effects of Daffodil Flowers and Cobalt Chloride on Vase Life of Cut Rose

Abstract

The effects of postharvest application of cobalt chloride were investigated on vaselife of rose stood individually in vials and the other ones placing daffodil flowers in a vase with arose flower. Therefore, roses were treated with: CoCl2 (100, 200, 300 mg L-1, respectively) ordistilled water (control). The results showed that the decreased vase life of rose flowers, afterdaffodil was placed in their vase water, is due to daffodil mucilage, which blocks water up take,mainly as a result of increased bacterial growth. Cobalt chloride inhibited vascular blockage in thestem of rose and maintained a high water flow rate through stems, leading to significantly wateruptake by cut flowers.
